Notes:
1. A = Address; D = Data; X = "Don't Care"; BAd = Any address in the block; N = Number of
bytes to be programmed; PA = Program address; PD = Program data; Gray shading = Not
applicable. All values in the table are hexadecimal. Some commands require both a com-
mand code and subcode.
2. These cells represent READ cycles (versus WRITE cycles for the others).
3. AUTO SELECT enables the device to read the manufacturer code, device code, block pro-
tection status, and extended memory block protection indicator.
4. AUTO SELECT addresses and data are specified in the Electronic Signature table and the
Extended Memory Block Protection table.
5. For any UNLOCK BYPASS ERASE/PROGRAM command, the first two UNLOCK cycles are
unnecessary.
6. BAd must be the same as the address loaded during the WRITE TO BUFFER PROGRAM
3rd and 4th cycles.
7. WRITE TO BUFFER PROGRAM operation: maximum cycles = 68(x8) and 36 (x16). UNLOCK
BYPASS WRITE TO BUFFER PROGRAM operation: maximum cycles = 66 (x8), 34 (x16).
