Microchip Technology, Inc. Memory - EEPROM - AT28C64E-12PI AT28C64E-12PI

The AT28C64E-12PI is a low-power, high-performance EEPROM memory device with a capacity of 64Kbits (8,192 words by 8 bits). It features a fast read access time of 120 ns and supports byte write cycles with a maximum time of 200 µs. The device operates on a supply voltage of 5V ± 10% and is compatible with both CMOS and TTL logic levels. This memory IC includes internal address and data latches, an automatic control timer for write cycles, and a READY/BUSY output for monitoring write status. It also incorporates data polling to confirm the completion of write operations. The AT28C64E is designed for high reliability, offering an endurance of up to 100,000 write cycles and a data retention period of 10 years. The device is available in multiple package types, including PDIP, SOIC, and TSOP, making it versatile for various applications. Its low active current of 30 mA and standby current of 100 µA contribute to its efficiency, making it suitable for power-sensitive designs.
