1 – IGLOO Device Family Overview

General Description

The IGLOO family of flash FPGAs, based on a 130-nm flash process, offers the lowest power FPGA, a

single-chip solution, small footprint packages, reprogrammability, and an abundance of advanced

features.

The Flash*Freeze technology used in IGLOO devices enables entering and exiting an ultra-low-

power mode that consumes as little as 5 µW while retaining SRAM and register data. Flash*Freeze

technology simplifies power management through I/O and clock management with rapid recovery

to operation mode.

The Low Power Active capability (static idle) allows for ultra-low-power consumption (from 12 µW)

while the IGLOO device is completely functional in the system. This allows the IGLOO device to

control system power management based on external inputs (e.g., scanning for keyboard stimulus)

while consuming minimal power.

Nonvolatile flash technology gives IGLOO devices the advantage of being a secure, low power,

single-chip solution that is live at power-up (LAPU). IGLOO is reprogrammable and offers time-to-

market benefits at an ASIC-level unit cost.

These features enable designers to create high-density systems using existing ASIC or FPGA design

flows and tools.

IGLOO devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well as

clock conditioning circuitry based on an integrated phase-locked loop (PLL). The AGL015 and

AGL030 devices have no PLL or RAM support. IGLOO devices have up to 1 million system gates,

supported with up to 144 kbits of true dual-port SRAM and up to 300 user I/Os.

M1 IGLOO devices support the high-performance, 32-bit Cortex-M1 processor developed by ARM

for implementation in FPGAs. Cortex-M1 is a soft processor that is fully implemented in the FPGA

fabric. It has a three-stage pipeline that offers a good balance between low-power consumption

and speed when implemented in an M1 IGLOO device. The processor runs the ARMv6-M instruction

set, has a configurable nested interrupt controller, and can be implemented with or without the

debug block. Cortex-M1 is available for free from Actel for use in M1 IGLOO FPGAs.

The ARM-enabled devices have Actel ordering numbers that begin with M1AGL and do not support

AES decryption.

Flash*Freeze Technology

The IGLOO device offers unique Flash*Freeze technology, allowing the device to enter and exit

ultra-low-power Flash*Freeze mode. IGLOO devices do not need additional components to turn off

I/Os or clocks while retaining the design information, SRAM content, and registers. Flash*Freeze

technology is combined with in-system programmability, which enables users to quickly and easily

upgrade and update their designs in the final stages of manufacturing or in the field. The ability of

IGLOO V2 devices to support a wide range of core voltage (1.2 V to 1.5 V) allows further reduction

in power consumption, thus achieving the lowest total system power.

When the IGLOO device enters Flash*Freeze mode, the device automatically shuts off the clocks

and inputs to the FPGA core; when the device exits Flash*Freeze mode, all activity resumes and

data is retained.

The availability of low-power modes, combined with reprogrammability, a single-chip and single-

voltage solution, and availability of small-footprint, high pin-count packages, make IGLOO devices

the best fit for portable electronics.

IGLOO Device Family Overview

1-2 v2.0

Flash Advantages

Low Power

Flash-based IGLOO devices exhibit power characteristics similar to those of an ASIC, making them

an ideal choice for power-sensitive applications. IGLOO devices have only a very limited power-on

current surge and no high-current transition period, both of which occur on many FPGAs.

IGLOO devices also have low dynamic power consumption to further maximize power savings;

power is even further reduced by the use of a 1.2 V core voltage.

Low dynamic power consumption, combined with low static power consumption and Flash*Freeze

technology, gives the IGLOO device the lowest total system power offered by any FPGA.

Security

The nonvolatile, flash-based IGLOO devices do not require a boot PROM, so there is no vulnerable

external bitstream that can be easily copied. IGLOO devices incorporate FlashLock, which provides a

unique combination of reprogrammability and design security without external overhead,

advantages that only an FPGA with nonvolatile flash programming can offer.

IGLOO devices utilize a 128-bit flash-based lock and a separate AES key to secure programmed

intellectual property and configuration data. In addition, all FlashROM data in IGLOO devices can

be encrypted prior to loading, using the industry-leading AES-128 (FIPS192) bit block cipher

encryption standard. AES was adopted by the National Institute of Standards and Technology

(NIST) in 2000 and replaces the 1977 DES standard. IGLOO devices have a built-in AES decryption

engine and a flash-based AES key that make them the most comprehensive programmable logic

device security solution available today. IGLOO devices with AES-based security allow for secure,

remote field updates over public networks such as the Internet, and ensure that valuable IP

remains out of the hands of system overbuilders, system cloners, and IP thieves. The contents of a

programmed IGLOO device cannot be read back, although secure design verification is possible.

Security, built into the FPGA fabric, is an inherent component of the IGLOO family. The flash cells

are located beneath seven metal layers, and many device design and layout techniques have been

used to make invasive attacks extremely difficult. The IGLOO family, with FlashLock and AES

security, is unique in being highly resistant to both invasive and noninvasive attacks. Your valuable

IP is protected and secure, making remote ISP possible. An IGLOO device provides the most

impenetrable security for programmable logic designs.

Single Chip

Flash-based FPGAs store their configuration information in on-chip flash cells. Once programmed,

the configuration data is an inherent part of the FPGA structure, and no external configuration

data needs to be loaded at system power-up (unlike SRAM-based FPGAs). Therefore, flash-based

IGLOO FPGAs do not require system configuration components such as EEPROMs or

microcontrollers to load device configuration data. This reduces bill-of-materials costs and PCB

area, and increases security and system reliability.

Live at Power-Up

The Actel flash-based IGLOO devices support Level 0 of the LAPU classification standard. This

feature helps in system component initialization, execution of critical tasks before the processor

wakes up, setup and configuration of memory blocks, clock generation, and bus activity

management. The LAPU feature of flash-based IGLOO devices greatly simplifies total system design

and reduces total system cost, often eliminating the need for CPLDs and clock generation PLLs. In

addition, glitches and brownouts in system power will not corrupt the IGLOO device's flash

configuration, and unlike SRAM-based FPGAs, the device will not have to be reloaded when system

power is restored. This enables the reduction or complete removal of the configuration PROM,

expensive voltage monitor, brownout detection, and clock generator devices from the PCB design.

Flash-based IGLOO devices simplify total system design and reduce cost and design risk while

increasing system reliability and improving system initialization time.

IGLOO flash FPGAs allow the user to quickly enter and exit Flash*Freeze mode. This is done almost

instantly (within 1 µs) and the device retains configuration and data in registers and RAM. Unlike

SRAM-based FPGAs the device does not need to reload configuration and design state from

IGLOO Low-Power Flash FPGAs

v2.0 1-3

external memory components; instead it retains all necessary information to resume operation

immediately.

Reduced Cost of Ownership

Advantages to the designer extend beyond low unit cost, performance, and ease of use. Unlike

SRAM-based FPGAs, Flash-based IGLOO devices allow all functionality to be live at power-up; no

external boot PROM is required. On-board security mechanisms prevent access to all the

programming information and enable secure remote updates of the FPGA logic. Designers can

perform secure remote in-system reprogramming to support future design iterations and field

upgrades with confidence that valuable intellectual property cannot be compromised or copied.

Secure ISP can be performed using the industry-standard AES algorithm. The IGLOO family device

architecture mitigates the need for ASIC migration at higher user volumes. This makes the IGLOO

family a cost-effective ASIC replacement solution, especially for applications in the consumer,

networking/communications, computing, and avionics markets.

Firm-Error Immunity

Firm errors occur most commonly when high-energy neutrons, generated in the upper atmosphere,

strike a configuration cell of an SRAM FPGA. The energy of the collision can change the state of the

configuration cell and thus change the logic, routing, or I/O behavior in an unpredictable way.

These errors are impossible to prevent in SRAM FPGAs. The consequence of this type of error can be

a complete system failure. Firm errors do not exist in the configuration memory of IGLOO flash-

based FPGAs. Once it is programmed, the flash cell configuration element of IGLOO FPGAs cannot

be altered by high-energy neutrons and is therefore immune to them. Recoverable (or soft) errors

occur in the user data SRAM of all FPGA devices. These can easily be mitigated by using error

detection and correction (EDAC) circuitry built into the FPGA fabric.

Advanced Flash Technology

The IGLOO family offers many benefits, including nonvolatility and reprogrammability, through an

advanced flash-based, 130-nm LVCMOS process with seven layers of metal. Standard CMOS design

techniques are used to implement logic and control functions. The combination of fine granularity,

enhanced flexible routing resources, and abundant flash switches allows for very high logic

utilization without compromising device routability or performance. Logic functions within the

device are interconnected through a four-level routing hierarchy.

IGLOO family FPGAs utilize design and process techniques to minimize power consumption in all

modes of operation.

Advanced Architecture

The proprietary IGLOO architecture provides granularity comparable to standard-cell ASICs. The

IGLOO device consists of five distinct and programmable architectural features (Figure 1-1 on

page 1-4 and Figure 1-2 on page 1-4):

• Flash*Freeze technology

• FPGA VersaTiles

• Dedicated FlashROM

• Dedicated SRAM/FIFO memory†

• Extensive CCCs and PLLs†

• Advanced I/O structure

The FPGA core consists of a sea of VersaTiles. Each VersaTile can be configured as a three-input

logic function, a D-flip-flop (with or without enable), or a latch by programming the appropriate

flash switch interconnections. The versatility of the IGLOO core tile as either a three-input lookup

table (LUT) equivalent or a D-flip-flop/latch with enable allows for efficient use of the FPGA fabric.

The VersaTile capability is unique to the Actel ProASIC® family of third-generation-architecture

flash FPGAs. VersaTiles are connected with any of the four levels of routing hierarchy. Flash

switches are distributed throughout the device to provide nonvolatile, reconfigurable interconnect

programming. Maximum core utilization is possible for virtually any design.

† The AGL015 and AGL030 do not support PLL or SRAM.

Flash*Freeze Technology

The IGLOO device has an ultra-low power static mode, called Flash*Freeze mode, which retains all

SRAM and register information and can still quickly return to normal operation. Flash*Freeze

technology enables the user to quickly (within 1 µs) enter and exit Flash*Freeze mode by activating

the Flash*Freeze pin while all power supplies are kept at their original values. In addition, I/Os and

global I/Os can still be driven and can be toggling without impact on power consumption, clocks

can still be driven or can be toggling without impact on power consumption, and the device retains

all core registers, SRAM information, and states. I/O states are tristated during Flash*Freeze mode

or can be set to a certain state using weak pull-up or pull-down I/O attribute configuration. No

power is consumed by the I/O banks, clocks, JTAG pins, or PLL, and the device consumes as little as

5 µW in this mode.

Flash*Freeze technology allows the user to switch to active mode on demand, thus simplifying the

power management of the device.

The Flash*Freeze pin (active low) can be routed internally to the core to allow the user's logic to

decide when it is safe to transition to this mode. It is also possible to use the Flash*Freeze pin as a

regular I/O if Flash*Freeze mode usage is not planned, which is advantageous because of the

inherent low power static (as low as 12 µW) and dynamic capabilities of the IGLOO device. Refer to

Figure 1-3 for an illustration of entering/exiting Flash*Freeze mode.

VersaTiles

The IGLOO core consists of VersaTiles, which have been enhanced beyond the ProASICPLUS® core

tiles. The IGLOO VersaTile supports the following:

• All 3-input logic functions—LUT-3 equivalent

• Latch with clear or set

• D-flip-flop with clear or set

• Enable D-flip-flop with clear or set

Refer to Figure 1-4 for VersaTile configurations.

IGLOO Device Family Overview

1-6 v2.0

User Nonvolatile FlashROM

Actel IGLOO devices have 1 kbit of on-chip, user-accessible, nonvolatile FlashROM. The FlashROM

can be used in diverse system applications:

• Internet protocol addressing (wireless or fixed)

• System calibration settings

• Device serialization and/or inventory control

• Subscription-based business models (for example, set-top boxes)

• Secure key storage for secure communications algorithms

• Asset management/tracking

• Date stamping

• Version management

The FlashROM is written using the standard IGLOO IEEE 1532 JTAG programming interface. The

core can be individually programmed (erased and written), and on-chip AES decryption can be used

selectively to securely load data over public networks (except in the AGL015 and AGL030 devices),

as in security keys stored in the FlashROM for a user design.

The FlashROM can be programmed via the JTAG programming interface, and its contents can be

read back either through the JTAG programming interface or via direct FPGA core addressing. Note

that the FlashROM can only be programmed from the JTAG interface and cannot be programmed

from the internal logic array.

The FlashROM is programmed as 8 banks of 128 bits; however, reading is performed on a byte-by-

byte basis using a synchronous interface. A 7-bit address from the FPGA core defines which of the 8

banks and which of the 16 bytes within that bank are being read. The three most significant bits

(MSBs) of the FlashROM address determine the bank, and the four least significant bits (LSBs) of

the FlashROM address define the byte.

The Actel IGLOO development software solutions, Libero® Integrated Design Environment (IDE)

and Designer, have extensive support for the FlashROM. One such feature is auto-generation of

sequential programming files for applications requiring a unique serial number in each part.

Another feature allows the inclusion of static data for system version control. Data for the

FlashROM can be generated quickly and easily using Actel Libero IDE and Designer software tools.

Comprehensive programming file support is also included to allow for easy programming of large

numbers of parts with differing FlashROM contents.

IGLOO devices (except the AGL015 and AGL030 devices) have embedded SRAM blocks along their

north and south sides. Each variable-aspect-ratio SRAM block is 4,608 bits in size. Available memory

configurations are 256×18, 512×9, 1k×4, 2k×2, and 4k×1 bits. The individual blocks have

independent read and write ports that can be configured with different bit widths on each port.

For example, data can be sent through a 4-bit port and read as a single bitstream. The embedded

SRAM blocks can be initialized via the device JTAG port (ROM emulation mode) using the UJTAG

macro (except in the AGL015 and AGL030 devices).

In addition, every SRAM block has an embedded FIFO control unit. The control unit allows the

SRAM block to be configured as a synchronous FIFO without using additional core VersaTiles. The

FIFO width and depth are programmable. The FIFO also features programmable Almost Empty

(AEMPTY) and Almost Full (AFULL) flags in addition to the normal Empty and Full flags. The

embedded FIFO control unit contains the counters necessary for generation of the read and write

address pointers. The embedded SRAM/FIFO blocks can be cascaded to create larger configurations.

PLL and CCC

IGLOO devices provide designers with very flexible clock conditioning circuit (CCC) capabilities.

Each member of the IGLOO family contains six CCCs. One CCC (center west side) has a PLL. The

AGL015 and AGL030 do not have a PLL.

The six CCC blocks are located at the four corners and the centers of the east and west sides. One

CCC (center west side) has a PLL.

IGLOO Low-Power Flash FPGAs

v2.0 1-7

All six CCC blocks are usable; the four corner CCCs and the east CCC allow simple clock delay

operations as well as clock spine access.

The inputs of the six CCC blocks are accessible from the FPGA core or from one of several inputs

located near the CCC that have dedicated connections to the CCC block.

The CCC block has these key features:

• Wide input frequency range (fIN_CCC) = 1.5 MHz up to 250 MHz

• Output frequency range (fOUT_CCC) = 0.75 MHz up to 250 MHz

• 2 programmable delay types for clock skew minimization

• Clock frequency synthesis (for PLL only)

Additional CCC specifications:

• Internal phase shift = 0°, 90°, 180°, and 270°. Output phase shift depends on the output

divider configuration (for PLL only).

• Output duty cycle = 50% ± 1.5% or better (for PLL only)

• Low output jitter: worst case < 2.5% × clock period peak-to-peak period jitter when single

global network used (for PLL only)

• Maximum acquisition time is 300 µs (for PLL only)

• Exceptional tolerance to input period jitter—allowable input jitter is up to 1.5 ns (for PLL

only)

• Four precise phases; maximum misalignment between adjacent phases of 40 ps × 250 MHz /

fOUT_CCC (for PLL only)

Global Clocking

IGLOO devices have extensive support for multiple clocking domains. In addition to the CCC and

PLL support described above, there is a comprehensive global clock distribution network.

Each VersaTile input and output port has access to nine VersaNets: six chip (main) and three

quadrant global networks. The VersaNets can be driven by the CCC or directly accessed from the

core via multiplexers (MUXes). The VersaNets can be used to distribute low-skew clock signals or for

rapid distribution of high-fanout nets.

I/Os with Advanced I/O Standards

The IGLOO family of FPGAs features a flexible I/O structure, supporting a range of voltages (1.2 V,

1.5 V, 1.8 V, 2.5 V, 3.0 V wide range, and 3.3 V). IGLOO FPGAs support many different I/O

standards—single-ended and differential.

The I/Os are organized into banks, with two or four banks per device. The configuration of these

banks determines the I/O standards supported (Table 1-1).

IGLOO Device Family Overview

1-8 v2.0

Each I/O module contains several input, output, and enable registers. These registers allow the

implementation of the following:

• Single-Data-Rate applications

• Double-Data-Rate applications—DDR LVDS, B-LVDS, and M-LVDS I/Os for point-to-point

communications

IGLOO banks for the AGL250 device and above support LVPECL, LVDS, B-LVDS, and M-LVDS. B-LVDS

and M-LVDS can support up to 20 loads.

Hot-swap (also called hot-plug, or hot-insertion) is the operation of hot-insertion or hot-removal of

a card in a powered-up system.

Cold-sparing (also called cold-swap) refers to the ability of a device to leave system data

undisturbed when the system is powered up, while the component itself is powered down, or

when power supplies are floating.

Wide Range I/O Support

Actel IGLOO devices support JEDEC-defined wide range I/O operation. IGLOO devices support both

the JESD8-B specification, covering 3 V and 3.3 V supplies, for an effective operating range of 2.7 V

to 3.6 V, and JESD8-12 with its 1.2 V nominal, supporting an effective operating range of 1.14 V to

1.575 V.

Wider I/O range means designers can eliminate power supplies or power conditioning components

from the board or move to less costly components with greater tolerances. Wide range eases I/O

bank management and provides enhanced protection from system voltage spikes, while providing

the flexibility to easily run custom voltage applications.

I/O Power-Up and Supply Voltage Thresholds for Power-On Reset

(Commercial and Industrial)

Sophisticated power-up management circuitry is designed into every IGLOO device. These circuits

ensure easy transition from the powered-off state to the powered-up state of the device. The many

different supplies can power up in any sequence with minimized current spikes or surges. In

addition, the I/O will be in a known state through the power-up sequence. The basic principle is

shown in Figure 2-1 on page 2-4 and Figure 2-2 on page 2-5.

There are five regions to consider during power-up.

IGLOO I/Os are activated only if ALL of the following three conditions are met:

1. VCC and VCCI are above the minimum specified trip points (Figure 2-1 on page 2-4 and

Figure 2-2 on page 2-5).

2. VCCI > VCC – 0.75 V (typical)

3. Chip is in the operating mode.

VCCI Trip Point:

Ramping up (V5 devices): 0.6 V < trip_point_up < 1.2 V

Ramping down (V5 Devices): 0.5 V < trip_point_down < 1.1 V

Ramping up (V2 devices): 0.75 V < trip_point_up < 1.05 V

Ramping down (V2 devices): 0.65 V < trip_point_down < 0.95 V

VCC Trip Point:

Ramping up (V5 devices): 0.6 V < trip_point_up < 1.1 V

Ramping down (V5 devices): 0.5 V < trip_point_down < 1.0 V

Ramping up (V2 devices): 0.65 V < trip_point_up < 1.05 V

Ramping down (V2 devices): 0.55 V < trip_point_down < 0.95 V

VCC and VCCI ramp-up trip points are about 100 mV higher than ramp-down trip points. This

specifically built-in hysteresis prevents undesirable power-up oscillations and current surges. Note

the following:

• During programming, I/Os become tristated and weakly pulled up to VCCI.

• JTAG supply, PLL power supplies, and charge pump VPUMP supply have no influence on I/O

behavior.

PLL Behavior at Brownout Condition

Actel recommends using monotonic power supplies or voltage regulators to ensure proper power-

up behavior. Power ramp-up should be monotonic at least until VCC and VCCPLX exceed brownout

activation levels (see Figure 2-1 and Figure 2-2 on page 2-5 for more details).

When PLL power supply voltage and/or VCC levels drop below the VCC brownout levels (0.75 V ±

0.25 V for V5 devices, and 0.75 V ± 0.2 V for V2 devices), the PLL output lock signal goes low and/or

the output clock is lost. Refer to the Brownout Voltage section in the Power-Up/-Down Behavior of

Low-Power Flash Devices chapter of the ProASIC®3 and ProASIC3E handbooks for information on

clock and lock recovery.

Internal Power-Up Activation Sequence

1. Core

2. Input buffers

3. Output buffers, after 200 ns delay from input buffer activation

To make sure the transition from input buffers to output buffers is clean, ensure that there is no

path longer than 100 ns from input buffer to output buffer in your design.

Thermal Characteristics

Introduction

The temperature variable in the Actel Designer software refers to the junction temperature, not

the ambient temperature. This is an important distinction because dynamic and static power

consumption cause the chip junction to be higher than the ambient temperature.

EQ 2-1 can be used to calculate junction temperature.

TJ = Junction Temperature = ΔT + TA

EQ 2-1

where:

TA = Ambient Temperature

ΔT = Temperature gradient between junction (silicon) and ambient ΔT = θja * P

θja = Junction-to-ambient of the package. θja numbers are located in Table 2-5 on page 2-6.

P = Power dissipation

Package Thermal Characteristics

The device junction-to-case thermal resistivity is θjc and the junction-to-ambient air thermal

resistivity is θja. The thermal characteristics for θja are shown for two air flow rates. The absolute

maximum junction temperature is 110°C. EQ 2-2 shows a sample calculation of the absolute

maximum power dissipation allowed for the AGL1000-FG484 package at commercial temperature

and in still air.

EQ 2-2

Disclaimer:

The simulation for determining the junction-to-air thermal resistance is based on JEDEC standards

(JESD51) and assumptions made in building the model. Junction-to-case is based on SEMI G38-88.

JESD51 is only used for comparing one package to another package, provided the two tests uses

the same condition. They have little relevance in actual application and therefore should be used

with a degree of caution.

Temperature and Voltage Derating Factors

Calculating Power Dissipation

Quiescent Supply Current

Quiescent supply current (IDD) calculation depends on multiple factors, including operating

voltages (VCC, VCCI, and VJTAG), operating temperature, system clock frequency, and power modes

usage. Actel recommends using the PowerCalculator and SmartPower software estimation tools to

evaluate the projected static and active power based on the user design, power mode usage,

operating voltage, and temperature.

Power Calculation Methodology

This section describes a simplified method to estimate power consumption of an application. For

more accurate and detailed power estimations, use the SmartPower tool in Actel Libero IDE

software.

The power calculation methodology described below uses the following variables:

• The number of PLLs as well as the number and the frequency of each output clock

generated

• The number of combinatorial and sequential cells used in the design

•The internal clock frequencies

Guidelines

Toggle Rate Definition

A toggle rate defines the frequency of a net or logic element relative to a clock. It is a percentage.

If the toggle rate of a net is 100%, this means that this net switches at half the clock frequency.

Below are some examples:

• The average toggle rate of a shift register is 100% because all flip-flop outputs toggle at

half of the clock frequency.

• The average toggle rate of an 8-bit counter is 25%:

– Bit 0 (LSB) = 100%

– Bit 1 = 50%

– Bit 2 = 25%

–…

– Bit 7 (MSB) = 0.78125%

– Average toggle rate = (100% + 50% + 25% + 12.5% + . . . + 0.78125%) / 8

Enable Rate Definition

Output enable rate is the average percentage of time during which tristate outputs are enabled.

When nontristate output buffers are used, the enable rate should be 100%.

The length of time an I/O can withstand IOSH/IOSL events depends on the junction temperature. The

reliability data below is based on a 3.3 V, 12 mA I/O setting, which is the worst case for this type of

analysis.

For example, at 110°C, the short current condition would have to be sustained for more than three

months to cause a reliability concern. The I/O design does not contain any short circuit protection,

but such protection would only be needed in extremely prolonged stress conditions.

No requirement 10 ns * 10 years (100°C)

*The maximum input rise/fall time is related to the noise induced into the input buffer trace. If the

noise is low, then the rise time and fall time of input buffers can be increased beyond the

maximum value. The longer the rise/fall times, the more susceptible the input signal is to the

board noise. Actel recommends signal integrity evaluation/characterization of the system to

ensure that there is no excessive noise coupling into input signals.

IGLOO DC and Switching Characteristics

2-80 v2.0

Differential I/O Characteristics

Physical Implementation

Configuration of the I/O modules as a differential pair is handled by Actel Designer software when

the user instantiates a differential I/O macro in the design.

Differential I/Os can also be used in conjunction with the embedded Input Register (InReg), Output

support for bidirectional I/Os or tristates with the LVPECL standards.

LVDS

Low-Voltage Differential Signaling (ANSI/TIA/EIA-644) is a high-speed, differential I/O standard. It

requires that one data bit be carried through two signal lines, so two pins are needed. It also

requires external resistor termination.

The full implementation of the LVDS transmitter and receiver is shown in an example in

Figure 2-13. The building blocks of the LVDS transmitter-receiver are one transmitter macro, one

receiver macro, three board resistors at the transmitter end, and one resistor at the receiver end.

The values for the three driver resistors are different from those used in the LVPECL

implementation because the output standard specifications are different.

Along with LVDS I/O, IGLOO also supports Bus LVDS structure and Multipoint LVDS (M-LVDS)

configuration (up to 40 nodes).
