NOTE:
1. Commands other than those shown above are reserved by Intel for future device implementations and
should not be used.
2.
First cycle command addresses should be the same as the operation’s target address. Examples: the first-
cycle address for the Read Device Identification Codes command should be the same as the Identification
Code address (IA); the first cycle address for the Program command should be the same as the word
address (WA) to be programmed; the first cycle address for the Erase/Program Suspend command should
be the same as the address within the block to be suspended; etc.
CA = Identification code address.
BA = Address within the block.
LPA = Lock Protection Address is obtained from the CFI (via the Read Query command). 1.8 V Dual-Plane
Flash memory’s LPA is at 0080h.
PA = User programmable 4-word protection address in the device identification plane.
PnA = Address within the partition.
QA = Query code address.
WA = Word address of memory location to be written.
3. SRD = Data read from the status register.
WD = Data to be written at location WA is latched on the rising edge of WE# or CE# (whichever goes high
first).
CD = Identifier code data.
PD =User programmable 4-word protection data.
QD = Query code data.
RCD = Read Configuration register code data presented on device addresses A
. Upper address bits can
select either partition
.
See
Table 8
for read configuration register bits descriptions.
4. Following the Read Device Identification Codes or Read Query commands, read operations output
manufacturer and device configuration or CFI query information and the read configuration register.
5. Read Device Identification and Read Query addresses must be within the bottom partition.
6. Following a block erase, program, and suspend operation, read operations access the status register.
7. The WSM recognizes either 40H or 10H program setup commands.
