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.
This Data Sheet may be revised by subsequent versions
or modifications due to changes in technical specifications.
