AT28C64B-15PI – ATMEL

The AT28C64B-15PI is a 64-kilobit (8K x 8) electrically erasable and programmable read-only memory (EEPROM) integrated circuit. Fabricated by Atmel, this device utilizes a parallel interface for data access, conforming to industry-standard asynchronous timing protocols. The “15” in the part number denotes a maximum access time of 150 nanoseconds, specifying the delay from address input to valid data output. It operates from a single 5V power supply and is housed in a 28-pin dual in-line package (DIP), facilitating through-hole mounting on printed circuit boards. The AT28C64B features byte-alterable memory, enabling individual byte writes and erases, and incorporates internal address and data latches for simplified system integration. Endurance is rated for a minimum of 10,000 write/erase cycles per byte, with data retention specified at 10 years minimum.
