DDR DIMM thermal monitoring — ±3°C accuracy over the full range
The MCP98244T-BE/MNY is a temperature monitoring system designed specifically for DIMM DDR memory modules, combining a sigma-delta ADC, an EEPROM for SPD data, and a register bank in a single 8-TDFN (2x3 mm) package.
I²C interface and alarm output — integration into the memory bus
An integrated output alarm and a dedicated fan output let the system respond to overtemperature events without polling the I²C bus, reducing firmware overhead in the BMC or memory controller.
Package and board-fit — 8-TDFN with exposed pad
Housed in an 8-WFDFN with exposed pad (supplier device package 8-TDFN 2x3 mm), the part requires a thermal land on the PCB to pull heat from the die — the pad should be connected to a copper plane for best thermal transfer.
