Onsemi EEPROM Serial 4-Kb SPD for DDR4 DIMM, Part #N34C04 | EEPROM | DEX

Onsemi EEPROM Serial 4-Kb SPD for DDR4 DIMM, Part #N34C04 | EEPROM | DEX is a EEPROM Serial 4−Kb, which implements the JEDEC JC42.4 (EE1004−v) Serial Presence Detect (SPD) specification for DDR4 DIMMs and supports the Standard (100 kHz), Fast (400 kHz) and Fast Plus (1 MHz) I2C protocols. One of the two available 2−Kb EEPROM banks (referred to as SPD pages in the EE1004−v specification) is activated for access at power−up. After power−up, banks can be switched via software command. Each of the four 1−Kb EEPROM blocks can be Write Protected by software command.

Features: • JEDEC JC42.4 (EE1004−v) Serial Presence Detect (SPD) Compliant • Temperature Range: −40°C to +125°C • Supply Range: 1.7 V − 3.6 V • I2C / SMBus Interface • Schmitt Triggers and Noise Suppression Filters on SCL and SDA Inputs • 16−Byte Page Write Buffer • Hardware Write Protection for Entire Memory • Low Power CMOS Technology • 2 x 3 x 0.5 mm UDFN8 Package • These Devices are Pb−Free and are RoHS Compliant
