GENERAL DESCRIPTION
The HY29F800A is an 8 Megabit, 5 volt only CMOS Flash memory organized as 1,048,576 (1M) bytes or 524,288 (512K) words. The device is offered in industry-standard 44-pin PSOP and 48-pin TSOP packages.
The HY29F800A can be programmed and erased in-system with a single 5-volt VCC supply. Internally generated and regulated voltages are provided for program and erase operations, so that the device does not require a high voltage power supply to perform those functions. The device can also be programmed in standard EPROM programmers. Access times as fast as 55 ns over the full operating voltage range of 5.0 volts ± 10% are offered for timing compatibility with the zero wait state requirements of high speed microprocessors. A 50 ns version operating over 5.0 volts ± 5% is also available. To eliminate bus contention, the HY29F800A has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls.
