The AT28HC256-70TU 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 10 ms maximum, allowing for 1 to 64-byte page write operations. The device operates with a single 5V ± 10% supply and is compatible with both CMOS and TTL inputs and outputs. Power consumption is low, with an active current of 80 mA and a CMOS standby current of 3 mA. The EEPROM includes hardware and software data protection, as well as data polling for end-of-write detection. It is built using high-reliability CMOS technology, offering an endurance of 10,000 or 100,000 cycles and a data retention period of up to 10 years. The AT28HC256-70TU is available in multiple package types, including 32-Lead CERDIP, 32-Lead Flatpack, 32-Lead CLCC, and 30-Pin PGA, making it suitable for various applications requiring reliable memory storage.
