Onsemi EEPROM Serial 2-Kb Microwire Part #NV34C02 | EEPROM | DEX

The NV34C02 is a 2-Kb Serial SPD EEPROM for DDR4 DIMM, 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
• Automotive Grade 1 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 UDFN Package
• These Devices are Pb−Free and are RoHS Compliant

Applications:

• Computing
