MCP98244
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):
