Product Summary

The AT34C02CY6-YH-T is a Two-wire Serial EEPROM with Permanent and Reversible Software Write Protect. The AT34C02CY6-YH-T provides 2048 bits of serial electrically-erasable and programmable read only memory (EEPROM) organized as 256 words of 8 bits each. The first-half of the device incorporates a permanent and a reversible software write protection feature while hardware write protection for the entire array is available via an external pin. Once the permanent software write protection is enabled, by sending a special command to the device, it cannot be reversed. However, the reversible software write protection is enabled and can be reversed by sending a special command.
