Overview
N34C04 EEPROM Serial 4-Kb SPD for DDR4 DIMM Description The N34C04 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.
