What is MCP98244T-BE/MNY used for?
The MCP98244T-BE/MNY is specifically designed for DDR3 and DDR4 DIMM memory modules, where it serves the dual role of a JEDEC-compliant temperature sensor and serial presence detect (SPD) EEPROM for storing module configuration data. System management controllers read the temperature output to implement thermal throttling and protect memory from overheating in server, workstation, and desktop PC platforms. The 3x2 mm TDFN-8 package fits within the tight space constraints of SODIMM and standard DIMM module designs.

Frequently Asked Questions
What is the temperature measurement accuracy of the MCP98244T-BE/MNY, and over what range does it apply?
The MCP98244T-BE/MNY achieves a maximum accuracy of ±3°C across its operating temperature range, which is consistent with JEDEC JC-42.4 specifications for DIMM temperature sensors. This level of accuracy is sufficient for the thermal management requirements of DDR3 and DDR4 memory modules, where the system controller monitors temperature to trigger throttling before reaching the 85°C thermal limit.
What is the significance of the integrated SPD EEPROM in the MCP98244T-BE/MNY for DDR memory modules?
The integrated SPD (Serial Presence Detect) EEPROM in the MCP98244T-BE/MNY stores critical memory module parameters such as capacity, speed grade, timing, and manufacturer data in a single 8-pin TDFN package. This dual-function integration saves PCB area on DIMM modules by eliminating a separate EEPROM chip, and the I2C/SMBus 2-wire interface allows the BIOS to read both SPD configuration data and live temperature readings from the same device.
How does the 3 mm x 2 mm TDFN-8 package of MCP98244T-BE/MNY benefit DIMM module layout?
The 3 mm x 2 mm x 0.75 mm TDFN-8 body of the MCP98244T-BE/MNY is among the smallest available for a combined temperature sensor and SPD EEPROM device, fitting easily within the height and area constraints of SODIMM and UDIMM designs. The no-lead surface mount termination supports high-density SMT reflow assembly, and the compact 8-pin footprint leaves more board space for DRAM components and routing on standard 133.35 mm DIMM PCBs.
Which communication protocol does the MCP98244T-BE/MNY use, and how many devices can share the same bus?
The MCP98244T-BE/MNY uses the I2C/SMBus 2-wire interface, which is the standard for JEDEC DIMM management and system thermal monitoring. Up to 8 devices can share the same SMBus segment using the 3-bit hardware address lines, allowing a single management controller to monitor temperature on 8 separate DIMM slots simultaneously. The bus operates at standard 100 kHz and fast 400 kHz I2C speeds, ensuring compatibility with server baseboard management controllers.
