nnnn DESCRIPTION
The MBM29LV650UE/651UE is a 64M-bit, 3.0 V-only Flash memory organized as 4M words of 16 bits each. The
device is designed to be programmed in system with the standard system 3.0 V VCC supply. 12.0 V VPP and
5.0 V VCC are not required for write or erase operations. The devices can also be reprogrammed in standard
EPROM programmers.
To eliminate bus contention the devices have separate chip enable (CE), write enable (WE), and output enable
(OE) controls.
The MBM29LV650UE/651UE is entirely command set compatible with JEDEC single-power-supply Flash stan-
dard. Commands are written to the command register using standard microprocessor write timings. Register
contents serve as input to an internal state-machine which controls the erase and programming circuitry. Write
cycles also internally latch addresses and data needed for the programming and erase operations.
Typically, each sector can be programmed and verified in about 0.5 seconds.
