The Microchip Technology 28C256-12B-UA is a 256-kilobit (32K x 8) CMOS Parallel EEPROM. This component features a 120ns access time and operates from a single 5V supply. Data retention is rated for a minimum of 10,000 write cycles. The device offers data polling and toggle bit features for efficient read/write operations. Its 32-terminal Ceramic Quad Flat Pack (CQFP) package, with a JEDEC code of R-XQCC-N32, is suitable for surface-mount applications. This EEPROM is employed in industrial control systems, telecommunications infrastructure, and automotive electronics where reliable non-volatile data storage is critical. The operating temperature range is from -55°C to +125°C.
