The HY29F002T is an 2 Megabit, 5 volt-only CMOS Flash memory organized as 262,144 (256K) bytes. The device is offered in industrystandard 32-pin TSOP and PLCC packages. The HY29F002T 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 55ns 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 45ns version operating over 5.0 volts 5% is also available. To eliminate bus contention, the
