■ DESCRIPTION
The MBM29F017A is a 16M-bit, 5.0 V-Only Flash memory organized as 2M bytes of 8 bits each. The 2M bytes of data is divided into 32 sectors of 64K bytes for flexible erase capability. The 8 bit of data will appear on DQ7 to DQ0. The MBM29F017A is offered in a 48-pin TSOP package. This device is designed to be programmed in system with the standard system 5.0 V VCC supply. A 12.0 V VPP is not required for program or erase operations. The device can also be reprogrammed in standard EPROM programmers.
The standard MBM29F017A offers access times between 70 ns and 120 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 MBM29F017A is command set compatible with JEDEC standard single-supply Flash standard. 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 device is similar to reading from 12.0 V Flash or EPROM devices.

■ FEATURES
