Note:
1. ADI = Address of Device identifier;A1=0, A0 =0 for manufacture code, A1=0, A0 =1 for device code.(Refer to
Table 3)
DDI = Data of Device identifier : C2H for manufacture code, 18H/19H for device code.
X = X can be VIL or VIH
RA=Address of memory location to be read.
RD=Data to be read at location RA.
2. PA = Address of memory location to be programmed.
PD = Data to be programmed at location PA.
SA = Address to the sector to be erased.
3. The system should generate the following address patterns: 555H or 2AAH to Address A0~A10.
Address bit A11~A16=X=Don't care for all address commands except for Program Address (PA) and Sector
Address (SA). Write Sequence may be initiated with A11~A16 in either state.
4. For chip protect verify operation : If read out data is 01H, it means the chip has been protected. If read out data
is 00H, it means the chip is still not being protected.
COMMAND DEFINITIONS
Device operations are selected by writing specific ad-
dress and data sequences into the command register.
Writing incorrect address and data values or writing
them in the improper sequence will reset the device to
the read mode. Table 1 defines the valid register
command sequences. Note that the Erase Suspend
(B0H) and Erase Resume (30H) commands are valid
only while the Sector Erase operation is in progress.
Either of the two reset command sequences will reset
the device(when applicable).
