Microchip Technology's 28C64 Series EEPROM, part number 28C64AX-20I-SO, provides 65536 bits of non-volatile memory organized as 8K words by 8 bits. This parallel interface CMOS device features a maximum access time of 200ns and operates asynchronously. Key functionalities include automatic write, bulk erase, and a minimum of 10,000 erase/write cycles. Data retention is specified at greater than 10 years. The 28C64AX-20I-SO is housed in a 28-lead Small Outline Package (PDSO28) with a 1.27mm terminal pitch, suitable for surface mounting. It operates within an industrial temperature range of -40°C to +85°C and utilizes a single 5V supply voltage (4.5V to 5.5V). This component finds application in industrial automation, automotive systems, and consumer electronics requiring reliable data storage.
