The Microchip Technology AT34C02D-XHM-T is a 2Kbit Serial Electrically-Erasable and Programmable Read Only Memory (EEPROM) device organized as 256 words of 8 bits each. It is designed to support the JEDEC EE1002 and EE1002A Serial Presence Detect (SPD) function, commonly used in DDR, DDR2, and DDR3 DIMM modules.
This EEPROM features an I2C-compatible 2-wire serial interface with compatibility for 400kHz at 1.7V-2.5V and 1MHz at 5.0V. It offers multiple 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. The device operates over a wide supply voltage range of 1.7V to 5.5V and has a maximum clock frequency of 1MHz.
With a self-timed write cycle of 5ms maximum, the AT34C02D-XHM-T boasts high reliability with an endurance of 1,000,000 write cycles and data retention of 100 years. It is available in an 8-lead TSSOP package, suitable for surface mounting. The operating temperature range is -40°C to 85°C (TA).
This component is optimized for industrial and commercial applications where low-power and low-voltage operations are essential. Its flexible write protection features allow users to protect none, the lower half, or the entire memory array based on application needs.
