The AT34C02D is a 2Kbit EEPROM designed for use in DDR, DDR2, and DDR3 DIMM modules, compliant with JEDEC EE1002 and EE1002A specifications. It features a memory organization of 256 words of 8 bits each and operates over a supply voltage range of 1.7V to 5.5V. The device supports an I¬=C-compatible 2-wire serial interface with a maximum clock frequency of 400kHz at lower voltages and 1MHz at 5.0V. This EEPROM includes multiple data protection schemes, such as permanent and reversible software write protection for the lower 128 bytes, as well as hardware write protection for the entire memory array. It has a self-timed write cycle time of 5ms and boasts an endurance of 1,000,000 write cycles with a data retention period of up to 100 years. The AT34C02D is available in various compact packages, including 8-pad UDFN, 8-lead TSSOP, 8-lead JEDEC SOIC, and 8-ball VFBGA, making it suitable for applications requiring low power and low voltage operation.
