Operation Temperature Condition -40°C~85°C
Legend:
X = Don’t care
RA = Address of the memory location 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 WE# or CE# pulse, whichever happens first. SA =
Address of the sector to be verified (in autoselect mode) or erased. Address bits A20–A12 uniquely select any sector.
Notes:
1.All values are in hexadecimal.
2.Except for the read cycle and the fourth cycle of the autoselect command sequence, all bus cycles are write cycles.
3.Data bits DQ15–DQ8 are don’t cares for unlock and command cycles.
4.Address bits A20–A11 are don’t cares for unlock and command cycles, unless SA or PA required.
5.No unlock or command cycles required when reading array data.
6. The Reset command is required to return to reading array data when device is in the autoselect mode, or if DQ5 goes high
(while the device is providing status data).
7.The fourth cycle of the autoselect command sequence is a read cycle.
8. For word mode data is 8Dh for factory locked and 0Dh for not factory locked. For byte mode data is 9Dh for factory locked and
1Dh for not factory locked.
9.The data is 00h for an unprotected sector and 01h for a protected sector. See “ Autoselect Command Sequence” for more
information.
10.Command is valid when device is ready to read array data or when device is in autoselect mode.
11.The system may read and program in non-erasing sectors, or enter the autoselect mode, when in the Erase Suspend mode.
The Erase Suspend command is valid only during a sector erase operation.
12.The Erase Resume command is valid only during the Erase Suspend mode.
