The AT28HC64B-70TU is a high-performance electrically-erasable and programmable read-only memory (EEPROM) with a capacity of 64K bits, organized as 8,192 words by 8 bits. It features a fast read access time of 70 ns and supports automatic page write operations, allowing for the writing of 1 to 64 bytes in a single cycle with a maximum page write cycle time of 10 ms. The device operates with a single 5 V ±10% supply and has low power dissipation, with an active current of 40 mA and a standby current of 100 µA. This EEPROM incorporates hardware and software data protection mechanisms, ensuring data integrity during write operations. It also features DATA polling and a toggle bit for end-of-write detection, enhancing reliability. The AT28HC64B-70TU is built using high-reliability CMOS technology, offering an endurance of 100,000 write cycles and a data retention period of up to 10 years. The device is available in a 28-lead thin small outline package (TSOP) and is suitable for industrial temperature ranges.
