AT28HC64BF-12SU EEPROM Memory IC 64Kbit Parallel 120 Ns 28-SOIC
Description:
The AT28HC64BF is a high-performance electrically-erasable and programmable read-only memory (EEPROM).
Its 64K of memory is organized as 8,192 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS
technology, the device offers access times to 55 ns with power dissipation of just 220 mW. When the device is
deselected, the CMOS standby current is less than 100 µA.
