NXP Semiconductors SE97B Temp Sensor with Onboard EEPROM
The NXP Semiconductors SE97B Temp Sensor measures temperature from -40°C to +125ºC with JEDEC Grade B ±1°C maximum accuracy between +75°C and +95°C critical zone and also provides 256 bytes of EEPROM memory communicating via the I²C/SMBus. The NXP Semiconductors SE97B Temp Sensor is typically mounted on a DDR3 dual in-line memory module (DIMM) measuring the DRAM temperature in accordance with the new JEDEC (JC-42.4) Mobile Platform Memory Module Temperature Sensor Component specification and also replacing the Serial Presence Detect (SPD). The NXP Semiconductors SE97B Temp Sensor with onboard EEPROM is designed for use in a variety of applications, including DDR2 and DDR3 memory modules, laptops, PCs, servers, hard disk drives, PC peripherals, and enterprise networking.Features
