MX26LV800T Macronix, MX26LV800T Datasheet - Page 8

• Manufacturer Part Number: MX26LV800T
• Description: 8M-Bit CMOS Single Voltage Flash Memory
• Manufacturer: Macronix

Note:
1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer code,A1=0, A0 = 1 for device code. A2-A18=do not care.
2. PA = Address of memory location to be programmed.
3. The system should generate the following address patterns: 555H or 2AAH to Address A10~A0 in word mode/AAAH or
P/N:PM1007
