Microchip Technology 28C64 8KX8 Serial EEPROM, part number 28C64AX-25-J, offers 65,536 bits of data storage organized as 8,192 words by 8 bits. This CMOS device features a maximum access time of 250ns and operates asynchronously. Key functionalities include automatic write, bulk erase, and a minimum of 10,000 erase/write cycles with a 1ms byte write time. Data retention exceeds 10 years. The component utilizes a parallel interface with 3-state outputs and is housed in a 28-lead CDIP package (JESD30 code R-GDIP-T28) with through-hole mounting. Typical applications include industrial control, automotive systems, and data logging where reliable non-volatile storage is essential. It operates within a temperature range of 0°C to 70°C and requires a supply voltage of 4.5V to 5.5V. Standby current is rated at 0.1mA maximum, with a maximum operating supply current of 30mA.
