Preliminary
H27UBG8T2A Series
32Gb (4096M x 8bit) NAND Flash
Notes:
1. Random Data Input/Output must be performed in a selected page.
2. Any command between 11h and 81h is prohibited except 70h, 78h, and FFh.
3. Multi Plane Random data-out must be used after Multi Plane read operations (Multi Plane Page Read, Multi Plane
Cache Read and Multi Plane Read for Copy Back).
4. Do not change Plane address order when using all Multi Plane operations.
5. All cache operation (cache program, cache read) is available only within a block.
6. Interleave operation between two chips are allowed. Multi Plane Read Status (78h) can be used to check each chip
status. It is prohibited to use Read Status command (70h) in interleaved operation.
Caution:
1. Any undefined command inputs are prohibited except for above command set.
2. Multi Plane page read, Multi Plane cache read, and Multi Plane read for copy-back must be used after Multi Plane
pro grammed page, Multi Plane cache program, and Multi Plane copy-back program.
1.8. Mode Selection
Notes:
1. X can be VIL or VIH. H = Logic level HIGH. L = Logic level LOW.
2. WP# should be biased to CMOS high or CMOS low for stand-by mode.
3. WE# and RE# during Read Busy must be keep on high to prevent unplanned command/address/data input or to
avert unintended data out. In this time, only Reset, Read Status, and Multi Plane Read Status can be inputted to
the device.
