AT34C04-SS5M-B

The AT34C04 provides 4,096 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 512 words of 8 bits each. The device’s cascading feature allows up to eight devices to share a common two‑wire bus. The Serial EEPROM operation is tailored specifically for DRAM memory modules with Serial Presence Detect (SPD) to store a module’s vital product data such as the module’s size, speed, voltage, data width and timing parameters. The AT34C04 is protocol compatible with the legacy JEDEC EE1002 specification (2-Kbit) devices enabling the AT34C04 to be utilized in legacy applications without any software changes.
