The onsemi CAT28C257G-12T is a 256Kbit (32K x 8) CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM) device. This parallel interface EEPROM offers a fast 120ns access time and robust 100,000 write cycle endurance. Featuring 100 years of data retention, it is suitable for applications requiring long-term non-volatile storage. The device operates with a single 5V supply and supports asynchronous operation. Its 32-lead PQCC package (JESD-30 Code R-PQCC-J32) is designed for surface mounting. The CAT28C257 series is commonly integrated into industrial control systems, automotive electronics, and data logging equipment requiring reliable data storage. It includes data polling and toggle bit features for efficient status monitoring.
