AM29F400B Features
* of the Am29F400, which was manufactured using 0.5 µm process technology. The standard device offers access times of 45, 50, 55, 70 and 90 ns, allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#)
