Product Summary

The HY29F400TT-55 is a 4 Megabit, 5 volt only CMOS Flash memory organized as 524,288 (512K) bytes or 262,144 (256K) words. The HY29F400TT-55 is offered in industry-standard 44-pin PSOP and 48-pin TSOP packages. The HY29F400TT-55 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 HY29F400TT-55 can also be programmed in standard EPROM programmers.
