Overview

DESCRIPTION

· The NXP SE97 is a temperature sensor and EEPROM integrated circuit designed for DDR memory modules.
· It measures temperature from -40°C to +125°C with ±1°C accuracy between +75°C and +95°C.
· It features 256 bytes of EEPROM memory for storing DRAM module and vendor information.
· The device communicates via I2C-bus/SMBus and operates within a voltage range of 3.0V to 3.6V.
· It is specifically designed for DIMM temperature monitoring and replaces the Serial Presence Detect (SPD) function.



FEATURES

· High-accuracy temperature sensing with JEDEC Grade B compliance.
· Integrated 256-byte EEPROM with write protection capability.
· ΔΣ Analog-to-Digital Converter for temperature measurement.
· Programmable alarm and critical temperature trip points.
· Configurable EVENT output signal for temperature monitoring.
· Supports both active LOW and active HIGH comparator outputs.
· Designed for DDR3 RDIMM and RDIMM ECC applications.



APPLICATIONS

· Temperature monitoring in DDR memory modules.
· Thermal management in thin and light notebooks.
· Dynamic control of memory traffic based on actual temperatures.
· Storage of DRAM vendor and product information.
· Thermal throttling and memory refresh rate scaling in mobile platforms.
