    DDR4 DIMM Temperature Sensor with EEPROM for SPD
    Features Description Meets JEDEC Specification
    -MCP98244 -> JC42.4-TSE2004B1
    Temperature Sensor with 4 Kbit Serial
    EEPROM for Serial Presence Detect (SPD) 1MHz, 2-wire I2C™ Interface Specified VDD Range: 1.7V to 3.6V Operating Current: 100 µA (typ., EEPROM Idle) Available Package: TDFN-8 Microchip Technology Inc.’s MCP98244 digital
    temperature sensor converts temperature from -40В°C
    and +125В°C to a digital word. This sensor meets
    JEDEC Specification JC42.4-TSE3000B1 Memory
    Module Thermal Sensor Component. It provides an
    accuracy of В±0.2В°C/В±1В°C (typical/maximum) from
    +75В°C to +95В°C with an operating voltage of 1.7V to
    3.6V. In addition, MCP98244 has an integrated
    EEPROM with two banks of 256 by 8 bit EEPROM (4k
    Bit) which can be used to store memory module details
    and vendor information. Temperature Sensor Features Temperature-to-Digital Converter (В°C) Sensor Accuracy (Grade B):
