Microchip Technology's 28C256-12I-K is a 262,144-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 asynchronously. The component supports automatic write, data polling, and toggle bit functions, facilitating efficient data manipulation. Designed for robust operation, it features an endurance rating of 10,000 write cycles and operates within a temperature range of -40°C to +85°C. The 28C256 series is suitable for applications in industrial control, automotive systems, and data logging where reliable, non-volatile storage is critical. It is housed in a 32-lead Ceramic Chip Carrier (CQCC32) package with a 1.27mm terminal pitch.
