●■ GENERAL DESCRIPTION
●The MBM29F800TA/BA is a 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(1) 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 MBM29LV800TA/BA 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.
●■ FEATURES
