AT28C64E-12JC [Microchip]

The AT28C64 is a low-power, high-performance 8,192 words by 8-bit nonvolatile electrically erasable and programmable read only memory. It features fast read access (120 ns), fast byte write (200 µs or 1 ms), self-timed write cycles, direct microprocessor control, low power consumption (30 mA active, 100 µA standby), high reliability (10⁴-10⁵ endurance cycles, 10-year data retention), 5V ±10% supply, CMOS/TTL compatibility, JEDEC byte-wide pinout, and commercial/industrial temperature ranges. Additional capabilities include chip erase and 32 bytes of extra EEPROM for device identification.
