The AT28C64-12SC is a 64Kbit (8K x 8) non-volatile EEPROM memory device from Quarktwin Technology Ltd. It features a fast read access time of 120 ns and supports byte write cycles of 200 µs or 1 ms, depending on the endurance option selected. The device operates on a supply voltage of 5V ± 10% and is compatible with both CMOS and TTL logic levels. This memory chip includes self-timed write cycles, internal address and data latches, and an automatic clear before write function. It also provides a READY/BUSY output for monitoring the status of write operations and supports data polling to confirm the completion of writes. The active current consumption is 30 mA, while the standby current is low at 100 µA. The AT28C64-12SC is designed for high reliability, with an endurance of either 10,000 or 100,000 write cycles and a data retention period of up to 10 years. It is available in multiple package types, including SOIC, making it suitable for a variety of applications in both commercial and industrial environments.
