• Manufacturer Part Number: IMX29F002
• Description: 2M-BIT [256K x 8] CMOS FLASH MEMORY
• Manufacturer: Macronix International

TABLE1. SOFTWARE COMMAND DEFINITIONS
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).
2. PA = Address of memory location to be programmed.
3.The system should generate the following address patterns: 555H or 2AAH to Address A0~A10. Address bit A11~A17=X=Don't
4.For Sector Protect Verification Operation : If read out data is 01H, it means the sector has been protected. If read out data is 00H,
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.

DDI = Data of Device identifier : C2H for manufacture code, 00B0h/0034h 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.
PD = Data to be programmed at location PA.
SA = Address to the sector to be erased.

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).
