Microchip Technology AT28C256E-30UM-883 is a 32K x 8 CMOS Parallel EEPROM featuring a 300ns access time. This device offers 262,144 bits of non-volatile memory with robust hardware and software data protection mechanisms. It supports data polling and a toggle bit for efficient read operations. Designed for demanding applications, it boasts a data retention of 10 years and an endurance of 100,000 write cycles. The AT28C256 series operates asynchronously within a wide temperature range of -55°C to +125°C. This component utilizes a 28-pin Ceramic Pin Grid Array (CPGA) package with perpendicular pins, suitable for high-reliability applications. Typical industries served include aerospace, defense, and industrial automation.
