Product Summary

The 29F800BA-70PFTN is an 8M-bit, 5.0 V-only Flash memory organized as 1M bytes of 8 bits each or 512K words of 16 bits each. The MBM29F800TA/BA is offered in a 48-pin TSOP(I) and 44-pin SOP packages. The 29F800BA-70PFTN 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 29F800BA-70PFTN can also be reprogrammed in standard EPROM programmers. The standard 29F800BA-70PFTN 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. The 29F800BA-70PFTN is pin and command set compatible with JEDEC standard E2PROMs. 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. Reading data out of the devices is similar to reading from12.0 V Flash or EPROM devices.
