AS-i networks are intended for industrial automation. The main advantage of AS-i solutions is that actuators and sensors are connected using a two-wire unshielded cable that is easy to install. This cable transports both power and information/data. AS-i network communication is based on the master-slave principle. The network can be extended (to cable lengths greater than 100m) by using the ASI in the repeater mode configuration. AS-i is a standard for the automation industry based on IEC 62026-2 and EN 50295. The device is available in a 28-pin SSOP package. 3 2.2 mF Block Diagram 5V 24V 8 MHz 10 mF U IN CAP RCAP ASI+ ASI- A2SI U OUT U5R ELECTRONIC INDUCTOR U5RD POWER SUPPLY OSC1/2 OSCILLATOR CCAP POWERFAIL DETECTION 4 DOx RECEIVE 4 ASIP DIGITAL LOGIC DIx DSR ASIN PST TRANSMIT THERMAL PROTECTION GND2 0V 4 GND1 GND Px IRD AMP IRD LED FID Figure 1: Block Diagram Data Sheet, Rev. 2.4, March 04, 2002 1/31 ASI Advanced AS-Interface IC 4 Pin Description Table 1: Pin Description PIN # Name Type Description 1 ASIP INOUT To be connected to the AS-i-line ASI+ via reverse polarity protection diode 2 ASIN INOUT To be connected to the AS-i-line ASI- 3 0V SUPPLY 4 IRD IN Addressing channel input 5 FID IN Input peripheral fault indication 6 OSC2 INOUT Crystal oscillator (8 MHz x-tal) 7 OSC1 IN 8 DO3 OUT Output of data D3 9 DO2 OUT Output of data D2 10 DO1 OUT Output of data D1 11 DO0 OUT Output of data D0 12 GND SUPPLY 13 P3 I/O Input/output of parameter P3 14 P2 I/O Input/output of parameter P2 / receive strobe in "Master Mode" 15 P1 I/O Input/output of parameter P1 / power fail in "Master Mode" 16 P0 I/O Input/output of parameter P0 / data clock in "Master Mode" 17 DI0 IN Input of data D0 18 DI1 IN Input of data D1 19 DI2 IN Input of data D2 20 DI3 IN Input of data D3 21 PST OUT 22 DSR I/O 23 U5RD SUPPLY 24 LED OUT 25 CAP IN/OUT 26 U5R OUT Internal 5V supply that might be used to supply external circuits as well 27 UOUT OUT Supply of external circuitry (e.g. sensor, actuator, etc.), approx.

The de-coupling circuit (electronic coil) is connected between UIN and UOUT pins and guarantees a high impedance seen at UIN. An external capacitor and resistor are required to allow a lowpass filter with a very high time constant. This high time-constant value is necessary to maximize the input impedance. The de-coupling circuit limits the current that can be drawn from UOUT. The power supply will shut down the de-coupling circuit in case of an overload condition to prevent a total malfunction of the complete AS-i line. The regulated 5 volt supply voltage is connected to pin U5R. Two external capacitors are necessary to cope with fast internal and external load changes (spikes). Current drawn from pin U5R (up to 4 mA) has to be subtracted from the total load current. The power supply circuit dissipates the major amount of power. The total power dissipation shall not exceed the specified values of Figure 6. The ground reference voltage for both UOUT and U5R is defined by the 0V pin. This pin must be connected to ASI- (ref. Figure 1). 6.2 Receiver The receiver detects signals on the AS-i line and delivers the appropriate pulses to the digital logic. The DC value of the input signal is removed and the AC signal is band-pass filtered. The digital output signals are 2 extracted from the sin -shaped input pulses by a set of comparators. The maximum voltage of the first negative pulse determines the threshold level for all following pulses. The maximum value is digitally filtered to guarantee stable conditions (burst spikes have no effect). This approach combines a fast adaptation to changing signal amplitudes with a high detection safety. The receiver delivers positive (P-PULSE) and negative (N-PULSE) pulses to the IC's logic. The logic resets the comparators after receiving the REC-RESET signal. When the receiver is turned on, the transmitter is turned off to reduce power consumption. Data Sheet, Rev. 2.4, March 04, 2002 3/31 ASI Advanced AS-Interface IC 6.3 Transmitter The transmitter draws a modulated current between ASIP and ASIN pins to generate the communication signals. The shape of the current corresponds to the integral of a sin2-function. The transmitter uses a current DAC and a high current driver. In order to activate high current drive capability, a small current will be turned on automatically prior to each transmission (slave mode only). The current will be ramped up slowly to avoid false voltage pulses on the AS-I line. The amount of circuitry between ASI+ and ASI- pins is minimized to allow high impedance values. When the transmitter is turned on, the receiver is turned off to reduce power consumption. 6.4 Digital Logic The digital logic block performs analysis of the received signal, controls reaction of the IC, transmits slave response, switches I/O-ports, and controls the internal EEPROM. Its principal function is described in detail in section 7. 6.5 Protection Circuitry The device has several protection cells that prevent disruption and malfunction of the complete AS-i line. The thermal detection shuts down the power supply in case of over-heating condition (silicon temperature > 140C typically for more than 2 seconds) and when UOUT is shorted to GND for more than 2 seconds. The device can only be reactivated by a power-on reset. An over-heating condition can occur by overloading any output pin. Therefore, the circuit monitors the operating conditions of the power supply (effectively monitors UOUT) and measures the temperature of the silicon. 6.6 Infrared Diode Input The photo current input can be used as an alternative communication pin in slave mode. The IRD circuitry will be turned off when the communication has been switched to AS-i line. In Slave mode the logic sets IRD input to photo-detector mode and disables CMOS mode. In this photo-detector mode, signals of an external photo diode are amplified. In CMOS mode (master/repeater mode only), input signals have to be CMOS levels between 0V and VU5R. 6.7 Power-Fail Detection The power-fail detector consists of a comparator that generates a logic signal in case the power supply drops below 22VDC (Power-Fail) for a time of more than tLoff (0.8 0.1 ms). The power fail signal will be presented at pin P1 in master mode only. Power-fail detection monitors the value of the ASIP voltage. It will activate a logic signal if power fails for more than 1ms. The device is then buffered by the external capacitor at UOUT and the internal circuitry will be reset when U5R supply voltage fails Data Sheet, Rev. 2.4, March 04, 2002 4/31 ASI Advanced AS-Interface IC OSC1/2 OSCILLATOR DATA-IN CLK P-PULSE N-PULSE RESET GND2 GND1 0V GND DO(3:0) INPUT STAGE DI(3:0) I/O STAGE DSR OUTPUT STAGE PST OUTPUT STAGE INPUT STAGE IRD LED FID INPUT STAGE OUT PARAM CMOS AC INPUT Current STAGE INPUT PARAM IRD In IN OVER-HEAT FAULT SEND-SBY LED THERMAL PROTECTION STRB OUT TRANSMIT PARAM SEND-D Logic ASIN OUTPUT STAGE DATA-STRB DIGITAL LOGIC REC-RESET AC RECEIVE ASIP IN POWER-FAIL U OUT POWERFAIL DETECTION POWER SUPPLY RESET ELECTRONIC INDUCTOR U5RD DATA-OUT U5R POWER-ON CAP A2SI UOUT SHUT-DOWN UIN P(3:0) OUTPUT STAGE Figure 3 : Functional Block Diagram Data Sheet, Rev. 2.4, March 04, 2002 5/31 ASI Advanced AS-Interface IC 7 Description of Digital Logic The digital logic is structured in four (4) parts (see Figure 4): 1) 2) 3) 4) the UART, which analyses the incoming signal from the AS-i line and ensures correct timing of output signals; the STATE MACHINE, which controls the reaction of the IC; the PORTS, which contain registers and digital I/O's; 2 and finally the EPROM, which contains the non-volatile data of the A SI circuit.

The input signal is Manchestercoded and active low. A falling edge of the IRD signal, which is conducted to ADD-IN, starts the receiving process and triggers the Activity-Checker. Receive-Muxer selects pin IRD as input for the receive data The IRD signal is connected with Send-Muxer to SEND-D via ADD-IN. The IRD signal is latched every 500 ns as long as there is activity on the input pin. If there is a high level on the IRD input longer then 7.0 s, ActivityChecker will recognize this as no activity and Receive-Muxer is returning to idle state. The information on pin IRD is transported to pin SEND-D with a delay of 2.0 s up to 2.5 s. The sender is always in non-standby mode. The SEND-SBY signal is constant low and there is no generation of ADD-CLK.

A pulse on the AS-i line starts the receiver and triggers the Activity-Checker through N-PULSE or P-PULSE. The Receive-Muxer selects AS-i-line pins as input for the receive data. The NPULSE and P-PULSE signals are latched every 250 ns as long as there is activity on the input pins. If there is a pulse distance on the AS-i-line inputs longer then 7.0 s, the receiver will recognize this as no activity and the Receive-Muxer is going to the idle state. The Pulse-Encoder is used to convert the active high pulse-coded signal to a active low Manchester-II-coded (MAN) signal. It will also check the pulse stream for timing and pulse errors (e.g. alternation error). In Master/Repeater mode the Pulse-Encoder additionally resynchronizes an error-free MAN telegram into a proper 3 s time base. This is to eliminate the pulse jitter of the transformed AS-i telegram. The synchronized MAN signal is sent to ADD-OUT through the Send-Muxer. ADD-OUT is connected to LED-OUT on a higher hierarchy level. All in all, information on the AS-i-line pins is transported to pin LED-OUT with a delay of 2.5 s up to 3.0 s. In Master/Repeater mode the sender is never in standby mode, hence SEND-SBY signal is always low. A generation of ADD-CLK is provided to simplify external processing of Manchester-coded data. The rising edge of the ADD-CLK signal is in the middle of the second half of the Manchester data assuring that correct binary data can be clocked into a shift register. The ADD-CLK starts with a rising edge 2.0 s after the falling edge of the start bit at ADD-OUT with a period of 6.0 s and a ratio of 1:1. The last rising edge of the ADD-CLK signal occurs 2.0 s after the falling edge of the end bit at ADD-OUT. If the received signal in the Master Mode is a valid slave answer with start bit, four (4) data bits, parity, and end bit and if a pause is following with a length greater than 6.0 s, the UART generates the active high REC-STRB signal with a pulse width of 500 ns. The REC-STRB signal is connected to the P2 Parameter Output in this mode. It appears 10.0 to 10.5 s after the rising edge of the end bit on AS-i-line. 7.1.1.3 Ports Functional assignments of some IC ports depend on the operational mode of the IC. Thus, these ports perform multiple functions that are related to a particular mode of the IC. In Master Mode, following signals and ports are connected: PIN Slave Function Master Repeater P0 Parameter output port bit 0 REC-CLK REC-CLK P1 Parameter output port bit 1 POWERFAIL - P2 Parameter output port bit 2 REC-STRB - LED LED Fault indicator output/addressing channel output MAN-OUT MAN-OUT IRD Addressing channel input MAN-IN MAN-IN Data Sheet, Rev. 2.4, March 04, 2002 8/31 ASI Advanced AS-Interface IC 7.1.2 Slave Mode After IC-reset, Receive-Muxer is watching the two input channels (AS-i-line and IRD pin) depending on a multiplex select signal MPX. MPX has a frequency of about 1.0 kHz. If MPX is low, the Receive-Muxer selects the AS-i-line and vice versa if it is high, it selects the IRD pin as data input. The channel, from which a valid master call is received first, will be locked until the next IC-reset occurs. 7.1.2.1 IRD Input Mode (Photo Diode Input) The photo diode current on the IRD input is Manchester-coded and low active (ref. 8.2.2 Addressing Channel Input IRD). A low level of the IRD signal starts the receiver and triggers the Activity-Checker. The Control-Unit is enabling the Receive-Register and the received information is clocked every 6 s into the Receive-Register. If there is a high level on the IRD input longer then 7.0 s, the Control-Unit will recognize this as no activity and the Receive-Register will be disabled. If the received information is a correct master call with Start-Bit, eleven Data-Bits, Parity-Bit, End-Bit, and following pause of either greater than 6.0 s (Synchronous Mode) or 18.0 s (Asynchronous Mode), the UART generates the internal active high REC-STRB signal with a pulse width of 500 ns. If the received telegram contained an error, the Control-Unit will not generate the REC-STRB signal but go to its asynchronous state waiting for a pause at the IRD input. After a pause was detected, the UART is ready to receive the next telegram from the IRD input. If a REC-STRB signal is generated, it occurs 9.5 s up to 10.0 s (Synchronous Mode) or 21.0 s up to 21.5 s (Asynchronous Mode), respectively, after the rising edge of the End-Bit on the IRD pin signal. If the slave was in asynchronous state, it now transforms to synchronous state. The Rec-Muxer is locked to the IRD input until the next IC-reset. After the generation of a REC-STRB signal the Control-Unit is waiting for about 6.0 s for the SEND-STRB to be generated by the Main-State-Machine. If the Control-Unit receives the active high SEND-STRB signal, it starts the transmission of the Send-Register data. Therefore, the Send-Register data will be converted to an active low Manchester II-coded (MAN) signal which is sent to the LED-OUT pin via ADD-OUT. The first falling edge of the MAN signal occurs 11.75 s (Synchronous Mode) or 12.25 s (Asynchronous Mode) after the rising edge of the REC-STRB signal. Hence, the delay from the rising edge of the End-Bit of the master call (IRD input) to the first falling edge of the slave response (LED output) is 21.25 to 21.75 s (Synchronous Mode) or 33.25 to 33.75 s (Asynchronous Mode). After the pause was detected, the UART is ready to receive the next telegram from the IRD input. In case the Control-Unit will not receive a SEND-STRB signal within the given time frame (for instance, if this slave was not addressed), it will check for activity on the IRD input. Otherwise, it will just wait for the end of the response time (60 s). In both cases the Control-Unit stays synchronous. Once a slave pause was detected, the UART is ready to receive the next telegram from the IRD input 7.1.2.2 AS-i Input Mode A signal on the AS-i-line generates two pulse-coded signals (N-PULSE, P-PULSE) at the receiver output with a minimum pulse width of 750 to 875 ns. A pulse on the AS-i line starts the receiver and triggers the ActivityChecker through N-PULSE or P-PULSE. The Pulse-Encoder is used to convert the active high pulse coded signal to an active low Manchester-II-coded (MAN) signal. It will also check the pulse stream for timing and pulse errors (e.g. alternation error). The ControlUnit enables the Receive-Register so that the received information can be clocked in every 6 s. If there is a pulse distance on the AS-i-line input longer than 7.0 s, the Control-Unit recognizes this as no activity and disables the Receive-Register. If the received information is a correct master call with Start-Bit, eleven (11) Data-Bits, Parity-Bit, End-Bit, and following pause of either greater than 6.0 s (Synchronous Mode) or 18.0 s (Asynchronous Mode), the UART generates the internal active high REC-STRB signal. If the received telegram contained an error, the ControlUnit will not generate the REC-STRB signal but go to its asynchronous state waiting for a pause at the AS-i line input. After a pause was detected the UART is ready to receive the next telegram from the AS-i line input. Data Sheet, Rev. 2.4, March 04, 2002 9/31 ASI Advanced AS-Interface IC If a REC-STRB signal is generated, it occurs 10.0 to 10.5 s (Synchronous Mode) or 21.5 to 22 s (Asynchronous Mode), respectively, after the rising edge (receiver comparator switching point) of the End-Bit on the AS-i line input. If the slave was in asynchronous state, it now transforms to synchronous state. The RecMuxer is locked to the AS-i line input until the next IC-reset. After the generation of a REC-STRB signal the Control-Unit is waiting for about 6.0 s for the SEND-STRB to be generated by the Main-State-Machine. If the Control-Unit receives the active high SEND-STRB signal (pulse width 500 ns), it starts the transmission of the Send-Register data. Therefore, the Send-Register data will be converted to an active low Manchester IIcoded (MAN) signal which is sent to the AS-i line transmitter via SEND-D. The first falling edge of the MAN signal occurs 11.75 s (Synchronous Mode) or 12.25 s (Asynchronous Mode) after the rising edge of the RECSTRB signal. Hence, the delay from the rising edge of the End-Bit of the master call (AS-i input) to the first falling edge of the slave response (AS-i output) is 21.75 to 22.25 s (Synchronous Mode) or 33.75 to 34.25 s (Asynchronous Mode). The SEND-SBY will always be set low 0.5 s after the rising edge of REC-STRB. This is to turn on the transmitter and let it settle at its operation point. The small offset current, which is required to operate the transmitter, will be ramped up slowly to avoid any false voltage pulses on the AS-i line. If all data is sent, the Control-Unit sets the sender in standby mode (SEND-SBY is high) and checks for a slave pause on the AS-i line input. After the pause was detected, the UART is ready to receive the next telegram from the AS-i line input. In case the Control-Unit will not receive a SEND-STRB signal within the given time frame (for instance, if this slave was not addressed), it will check for activity on the AS-i line. If any activity is detected in a time frame of about 60 s (another slave is transmitting data), the Control-Unit will wait for the next pause (slave pause). Otherwise, it will just wait for the end of the response time (60 s). In both cases the Control-Unit stays synhronus. Once a slave pause was detected, the UART is ready to receive the next telegram from the AS-i line input. 7.1.2.3 Ports Although the ASI can still store the AS-i Slave IO-Configuration Code it does not decode the value to configure the direction of the Data-Port signals. The ASI rather has distinctive Data-Out and Data-In ports which do always work in parallel. If bidirectional Data I/O is desired on top of a single Data-Port only (for backwards compatibility), the Data-Out pins and the Data-In pins need to be shorted on the circuit board respectively and the nonvololatile Multiplex flag has to be set TRUE. In that case the output ports will switch to high impedance state for a certain time following the rising edge of the Data-Strobe and allow the input data to be put on the Data-Port. The input data will be read inverted if the nonvolotile Invert_Data_In flag is TRUE. This feature will simplify the circuitry for NPN-inputs. Note: The Multiplex and the Invert_Data_In flags are Configuration flags which are stored in the Firmware region of the internal EPROM. For a complete overview of the EPROM content please see the ASI Application Notes. The parameter port is always in bidirectional mode. The input data is the result of a wired-AND between the open drain output drivers and the application drivers. 7.1.2.4 Watchdog Compliant to the AS-i Complete Specification, the IC contains an independent watchdog which is generally enabled by setting Watchdog_Active flag in the EPROM to TRUE. Data Sheet, Rev. 2.4, March 04, 2002 10/31 ASI Advanced AS-Interface IC The watchdog will be activated for any slave address uneven to zero (0) after the reception of a Write_Parameter Request at the particular Slave Address. It will be deactivated by any circuit Reset and after the reception of a Delete_Address Request. When activated, the Watchdog will be reset by every Write_Parameter and Data_Exchange Request received by the Slave. If no such request was received by the particular Slave within 40ms, a Hardware Reset will be performed and all Data and Parameter Outputs are switched inactive. 7.1.2.5 LED Output An active FID (logic high) signal causes a flashing status LED (frequency approx. 2Hz) and Bit 1 of the AS-i Slave Status-Register (S1) is set as well. If FID is not active (logic low), S1 is cleared. In that case the status LED operation depends on the Data-Exchange-Disable flag. The Data-Exchange-Disable is set to TRUE by each Reset of the ASI. It becomes cleared (set to FALSE) after the first reception of a Write_Parameter Request. If the Data-Exchange-Disable flag is set, no data exchange can be performed through the Data Ports which is indicated by a steady-on LED. Note: An active FID has priority and will cause a flashing LED even if the Data-Exchange-Disable flag is set. If the UART has selected the IRD input channel, the LED output is again overriden by the Addressing Channel output. In this mode the LED pin does not operate as indicator LED output and periphery failures or status information can not be signaled. 7.1.2.6 Overtemp shutdown The ASI continuously observes its silicon die temperature. If the temperature rises above 140C the IC will be put into shut-down and stay there until the next power-on reset occurs. 7.1.2.7 State Machine 2 The so-called Main-State-Machine performs the central control of the A SI IC in terms of operation mode selection, EEPROM access control, processing of master requests and the control of the IC ports. The MainState-Machine interfaces with the UART through the Receive- and the Send-Register as well as certain strobe signals. To avoid the situation in which a slave IC gets locked in a not allowed state (i.e by imission of strong electromacnetic radiation) and thereby would jeopardize the entire system, all prohibited states of the state machine will lead to a RESET which is comparable to the AS-i call "Reset Slave (RES)". 7.2 Summary of Master Calls 2 In the following diagram all Master Calls that will be decoded by the A SI are listed. The "Enter Program Mode" call is intended for factory programming of the IC only. In order to achieve EEPROM firmware protection and to comply to the complete AS-i specification, the call "Enter Program Mode" has to be deactivated before shipment of the slave.

Dependent on the type of master call the I3 bit carries the select bit information (Sel) or the inverted select bit information (~Sel). Program Mode Provided that the non-volatile configuration flag, Program-Mode-Disable, has not been set, the device can be transferred in program mode by utilizing the "Enter Program Mode" call. Please refer to the ASI Application Notes [4] for details of the programming process. AS-i Complete Specification compliance note: In order to ensure full compliance with the AS-i Complete Specification, the Program-Mode-Disable flag must be set in the final manufacturing and configuration process before an AS-i slave device is being delivered to field application users.

The devices are tested within the recommended range of VASIP - VASIN, VIN - V0V, qamb = +25C (+ 85C and - 25C on sample base only) unless otherwise stated. Unused input pins shall be connected to a suitable potential within the application circuit because there are no internal pull-up/down resistors. It is recommended to connect these pins either to 0V or via resistor to UOUT or U5R respectively. With an external LOW signal at the data strobe pin DSR (pull-down open drain driver) for more than 44s, the IC will execute its reset procedure. During power on procedure all data and parameter ports will stay on highimpedance state. If the IC has been put in its initialization procedure by an external reset via DSR, the LED pin should not be toggled externally to avoid that the IC control logic transfers to test mode.

The photo-diode can be connected to the pins IRD and 0V directly. The IRD input is a AC current input. A valid signal at the current input has to have a certain amplitude (range) and should not exceed a certain offset value (see Figure 10 and Table 9). A logic "low" at the IRD input will be detected, if the present signal value drops below IIRDO, and a "high" will be detected, if its present value is greater than IIRDO + IIRDA.

The S1 status bit is equivalent to the FID input signal. A FID transition will occur at S1 with a certain delay, because a synchronizer circuit is put in between.

Higher values do not improve the impedance but do increase the turn-on time. The turn-on time also depends on the load capacitor at UOUT. After connecting the slave to the power the capacitor is charged with the maximum current IUOUT. The impedance will increase when the voltage allows the analog circuitry to fully operate.

Figure 14 shows an application circuit in 2 2 which the A SI is replacing an ASI3+ circuit. Finally, Figure 15 shows how the A SI circuit can be used to perform the analog/digital interface between the AS-i-line and the master electronics. Furthermore this figure shows that the IC can be used in repeater applications as well. 10.1 EMC Precautions Precaution must be taken to avoid radio frequency interference. It is recommended to keep input lines as short as possible and to connect unused inputs to UOUT through a pull-up resistor. Furthermore, the supply pins should be de-coupled with ceramic capacitors (10 to 100 nF) in addition to the normal de-coupling capacitors. Also, it is recommended to connect a pull-up resistor from DSR (pin 22) to UOUT or U5R in order to avoid unintentional reset under difficult EMC conditions. 10.2 Typical Slave Application A2SI 28 7 UIN OSC1 8 MHz 6 OSC2 17 18 19 20 DI_0 DI_1 DI_2 DI_3 DO0 DO1 DO2 DO3 11 10 9 8 DO_0 DO_1 DO_2 DO_3 P0 P1 P2 P3 16 15 14 13 P0 P1 P2 P3 DSR 1 ASIP ASI DI0 DI1 DI2 DI3 PST 39V/1W FID 2 ASI 25 R CAP U5RD ASIN CAP C CAP 0V GND PST 5 Fault Input 23 26 U OUT 27 IRD DS&Reset 21 U5R LED 3 22 24 22 k W +5V +24V RED GREEN 4 2.2F 10 m F 10n 10n 12 0V Figure 13: Typical Application, Slave Mode Note: Figure 13 and Figure 14 show all digital (data and parameter) ports without the application specific connections.
