Description
The MFM8516 is a 4M Bit CMOS 5V only Flash
monolithic device organised : 512K x 8. The device
offers fast access times of 70/90/120 and 150ns and
5V program/erase.
The device has a 64 KByte sector size. The Program
and Erase procedure is simplified via automatic
program and erase algorithms.
The MFM8516 has a 10K cycle write erase cycle
endurance (100K cycle E-Part) and a 10 year data
retention time.
524,288 bit FLASH EEPROM
