AT34C04-SS5M-B by Microchip Technology
4Kb I2C compatible Serial Present Detect (SPD) Serial EEPROM for DDR4 DIMM modules
| Status: | Active |
|---|---|
| Series: | AT34C04 |
| RoHS: | Compliant |
The Microchip AT34C04 is a 4 Kb Serial EEPROM utilizing an I2C (2-wire) serial interface. The device is organized as one block of 512 x 8 and is optimized for use in consumer and industrial applications where reliable and dependable nonvolatile memory storage is essential. The EEPROM is available in a variety of space-saving packaging options with an operating range of 1.7 to 3.6V.
The AT34C04 is tailored specifically for DRAM memory modules with Serial Presence Detect (SPD). The device incorporates a Reversible Software Write Protection (RSWP) feature enabling the capability to selectively write protect any or all of the four 128-byte quadrants.
