Microchip Technology's 28C256-12-L is a 262144-bit CMOS Electrically Erasable Programmable Read-Only Memory organized as 32K words by 8 bits. This parallel interface EEPROM offers a maximum access time of 120ns and operates from a 5V supply. It features automatic write and data polling for efficient data management, along with a toggle bit for write completion indication. The component supports a minimum of 10,000 erase/write cycles and operates within a temperature range of 0°C to 70°C. Housed in a 32-lead PQCC package, the 28C256-12-L is suitable for applications in industrial control, automotive systems, and consumer electronics requiring reliable non-volatile data storage.
