Legend:
X = Don’t care
RA = Address of the memory to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed. Addresses latch on the falling edge of the WE# or CE# pulse, whichever
happens later.
PD = Data to be programmed at location PA. Data latches on the rising edge of the WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or erased. Address bits Amax–A16 uniquely select any sector.
WBL = Write Buffer Location. The address must be within the same write buffer page as PA.
WC = Word Count is the number of write buffer locations to load minus 1.
PWD = Password
PWDx = Password word0, word1, word2, word3. word 4, word 5, word 6, and word 7.
DATA = Lock Register Contents: PD(0) = SecSi Sector Protection Bit, PD(1) = Persistent Protection Mode Lock Bit, PD(2) =
Password Protection Mode Lock Bit.
Notes:
1. See Table 1 for description of bus operations.
2. All values are in hexadecimal.
3. Except for the read cycle, and the 4th, 5th, and 6th cycle of the autoselect command sequence, all bus cycles are write
cycles.
