Product Summary

The AM29F400BT-90SI is a 4 Mbit, 5.0 volt-only Flash memory organized as 524,288 bytes or 262,144 words. The device is offered in 44-pin SO and 48-pin TSOP packages. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. The AM29F400BT-90SI is designed to be programmed insystem with the standard system 5.0 volt VCC supply. A 12.0 V VPP is not required for write or erase operations. The AM29F400BT-90SI can also be programmed in standard EPROM programmers. This device is manufactured using 0.35 μm process technology, and offers all the features and benefits of the Am29F400, which was manufactured using 0.5 μm process technology. The standard device offers access times of 55, 60, 70, 90, 120, and 150 ns, allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls.
