Notes:
1. See Table 1 for descriptions of bus operations.
2. All values are in hexadecimal.
3. Except when reading array or automatic select data, all bus cycles are write operation.
4. Address bits are don't care for unlock and command cycles, except when PA or SA is required.
5. No unlock or command cycles required when device is in read mode.
6. The Reset command is required to return to the read mode when the device is in the automatic select mode or if
Q5 goes high.
7. The fourth cycle of the automatic select command sequence is a read cycle.
8. The data is 00h for an unprotected sector/sector block and 01h for a protected sector/sector block. In the third
cycle of the command sequence, address bit A21=0 to verify sectors 0~63, A21=1 to verify sectors 64~134 for
Top Boot device.
9. The data is 88h for factory locked and 08h for not factory locked.
10.The system may read and program functions in non-erasing sectors, or enter the automatic select mode, when in
the erase Suspend mode. The Erase Suspend command is valid only during a sector erase operation.
11.The Erase Resume command is valid only during the Erase Suspend mode.
12.Command is valid when device is ready to read array data or when device is in automatic select mode.
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 are latched on the falling edge of the WE or
CE pulse, whichever happen later.
DDI=Data of device identifier
C2H for manufacture code
C9/CBH (Top/Bottom) for device code
PD=Data to be programmed at location PA. Data is
latched on the rising edge of WE or CE pulse.
SA=Address of the sector to be erase or verified (in
autoselect mode).
Address bits A21-A12 uniquely select any sector.
