The AT28HC256F-90FM/883 is a military-grade 256-Kbit (32,768 x 8) high-speed paged parallel EEPROM. It features a fast read access time of 90 ns and supports automatic page write operations with a page write cycle time of 3 ms or a maximum of 10 ms for 1 to 64 bytes. The device operates with a single 5V ± 10% supply and has low power dissipation, with an active current of 80 mA and a CMOS standby current of 3 mA. This EEPROM incorporates hardware and software data protection mechanisms, along with data polling for end-of-write detection. It is built using high-reliability CMOS technology, offering an endurance of 10,000 to 100,000 write cycles and a data retention period of up to 10 years. The device is compatible with both CMOS and TTL inputs and outputs, and it comes in various package types including 32-Lead CERDIP, 32-Lead Flatpack, 32-Lead CLCC, and 30-Pin PGA. The AT28HC256F-90FM/883 is suitable for applications requiring reliable memory storage in military and industrial environments.
