The AT28C64-25JI is a 64Kbit (8K x 8) non-volatile EEPROM memory device from Quarktwin Technology Ltd. It features a fast read access time of 250 ns and a byte write time of 1 ms. The device operates with a supply voltage of 5V ± 10% and is compatible with both CMOS and TTL logic levels. It includes internal address and data latches, an automatic control timer for write cycles, and a READY/BUSY output for monitoring write status. This memory chip is designed for low power consumption, with an active current of 30 mA and a standby current of 100 µA. It offers high reliability with an endurance of up to 100,000 write cycles and a data retention period of 10 years. The AT28C64-25JI is available in a 32-lead PLCC package and is suitable for commercial and industrial temperature ranges. It also includes features such as data polling to confirm write completion and write protection mechanisms to prevent inadvertent writes.
