Note: X Don’t Care, PA Program Address, PD Program Data, BA Any address in the Block.
All values in the table are in hexadecimal.
The Command Interface only uses A–1, A0-A10 and DQ0-DQ7 to verify the commands; A11-A15, DQ8-DQ14 and DQ15 are Don’t Care.
DQ15A–1 is A–1 when BYTE is VIL or DQ15 when BYTE is VIH.
Read/Reset. After a Read/Reset command, read the memory as normal until another command is issued.
Auto Select. After an Auto Select command, read Manufacturer ID, Device ID or Block Protection Status.
Program, Unlock Bypass Program, Chip Erase, Block Erase. After these commands read the Status Register until the Program/Erase
Controller completes and the memory returns to Read Mode. Add additional Blocks during Block Erase Command with additional Bus Writ e
Operations until the Timeout Bit is set.
Unlock Bypass. After the Unlock Bypass command issue Unlock Bypass Program or Unlock Bypass Reset commands.
Unlock Bypass Reset. After the Unlock Bypass Reset command read the memory as normal until another command is issued.
Erase Suspend. After the Erase Suspend command read non-erasing memory blocks as normal, issue Auto Select and Program commands
on non-erasing blocks as normal.
Erase Resume. After the Erase Resume command the suspended Erase operation resumes, read the Status Register until the Program/
Erase Controller completes and the memory returns to Read Mode.
