TABLE 4. MX29LV002C T/B COMMAND DEFINITIONS
Notes:
1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer code,A1=0, A0 = 1 for device code. A2-A17=do
not care.
(Refer to table 3)
DDI = Data of Device identifier : C2H for manufacture code, 59H/5AH (Top/Bottom) 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 of the sector to be erased.
3. The system should generate the following address patterns: 555H or 2AAH to Address A11~A0.
Address bit A12~A18=X=Don't care for all address commands except for Program Address (PA) and Sector
Address (SA). Write Sequence may be initiated with A12~A18 in either state.
4. For Sector Protect Verify operation:If read out data is 01H, it means the sector has been protected. If read out data
is 00H, it means the sector is still not being protected.
