The Atmel AT34C02D-XHM-T is a 2,048-bit Serial Electrically-Erasable and Programmable Read-Only Memory (EEPROM) specifically designed to support the JEDEC EE1002 and EE1002A Serial Presence Detect (SPD) function in DDR, DDR2, and DDR3 DIMM modules. It operates with a single supply voltage from 1.7V to 5.5V and utilizes an I2C-compatible 2-wire serial interface, supporting speeds up to 400kHz at lower voltages and 1MHz at 5.0V.
This EEPROM offers robust data protection schemes, including permanent and reversible software write protection for the lower 128 bytes, and hardware write protection for the entire array via the WP pin. It supports 16-byte page write modes, allowing partial page writes, and features Schmitt trigger filtered inputs for enhanced noise suppression. The device boasts high reliability with an endurance of 1,000,000 write cycles and data retention of 100 years.
The AT34C02D-XHM-T is available in multiple package options including 8-pad 2x3mm UDFN, 8-lead TSSOP, 8-lead JEDEC SOIC, and 8-ball VFBGA, making it suitable for space-constrained applications. It is optimized for industrial and commercial applications requiring low-power and low-voltage operation.
