4 Megabits (512K X 8-bits / 256K X 16-bits)

The MBM29F400TC MBM29F400BC is a 4M-bit, 5.0 V-only Flash memory organized as 512K bytes of 8 bits each or 256K words of 16 bits each. The MBM29F400TC MBM29F400BC is offered in a 48-pin TSOP and 44-pin SOP packages. This device is designed to be programmed in-system with the standard system 5.0 V VCC supply. 12.0 V VPP is not required for write or erase operations. The devices CAN also be reprogrammed in standard EPROM programmers. The standard MBM29F400TC BC offers access times 55 ns and 90 ns allowing operation of high-speed Microprocessors without wait states. To eliminate bus contention the device has separate chip enable (CE), write enable (WE), and output enable (OE) controls.
