MX29F001T Macronix, MX29F001T Datasheet - Page 5

• Manufacturer Part Number: MX29F001T
• Description: 1M bit CMOS Flash Memory
• Manufacturer: Macronix

TABLE 1. 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
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.
4. For chip protect verify operation : If read out data is 01H, it means the chip has been protected. If read out data
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

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.
PD = Data to be programmed at location PA.
SA = Address to the sector to be erased.
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.
