Microchip Technology, Inc. Memory AT28C64X-20PI

The AT28C64X-20PI is a 64Kbit (8K x 8) parallel EEPROM memory device designed for low power consumption and high performance. It features a fast read access time of 200 ns and a byte write time of 1 ms, with self-timed write cycles that include internal address and data latches. The device operates on a supply voltage of 5V ± 10% and is compatible with both CMOS and TTL logic levels. This memory chip has a low active current of 30 mA and a standby current of 100 µA, making it suitable for power-sensitive applications. It offers high reliability with an endurance of 10^5 write cycles and a data retention period of up to 10 years. The AT28C64X-20PI is available in various package types, including PDIP, SOIC, and TSOP, and is suitable for both commercial and industrial temperature ranges. The device also includes features such as data polling and a ready/busy output to facilitate efficient operation during write cycles.
