What are the key features of MCP98243-BE/ST?
- JEDEC JC-42.4 compliant DIMM temperature sensor with I2C serial output for direct integration into DDR memory modules
- ±2°C maximum accuracy in a compact 8-pin TSSOP package (4.4 mm x 3 mm x 1.2 mm) for space-constrained DIMM designs
- Pb-free TSSOP-8 construction with e3 moisture sensitivity rating, meeting modern RoHS and JEDEC assembly requirements
What is MCP98243-BE/ST used for?
The MCP98243-BE/ST is designed for DDR SDRAM DIMM modules where JEDEC-standard thermal monitoring is required by the memory controller or system management firmware. Server motherboards and workstation memory subsystems use it to trigger throttling or shutdown when DIMM temperatures exceed safe limits, protecting memory integrity during heavy computational loads. It also suits embedded computing modules and industrial single-board computers that follow JEDEC SPD specifications for thermal reporting.

Frequently Asked Questions
What accuracy does the MCP98243-BE/ST provide for DIMM thermal monitoring?
The MCP98243-BE/ST achieves a maximum accuracy of ±2°C, which meets the JEDEC JC-42.4 specification for DIMM temperature sensors. This level of precision is sufficient for memory thermal throttling decisions in server and workstation applications, where the system management controller triggers corrective action before DRAM junction temperatures reach critical thresholds during sustained memory-bandwidth-intensive workloads.
How small is the MCP98243-BE/ST package, and does it fit standard DIMM PCB layouts?
The MCP98243-BE/ST is housed in an 8-pin TSSOP package measuring 4.4 mm long, 3 mm wide, and 1.2 mm tall. This compact profile was designed to fit within the constrained height and footprint of standard 1.2 mm-profile DDR DIMM modules, allowing system designers to comply with JEDEC thermal sensor placement requirements without PCB re-spin or height clearance concerns.
How long is the production lead time for the MCP98243-BE/ST, and what should procurement teams plan for?
The MCP98243-BE/ST carries a factory lead time of 13 weeks from Microchip. Procurement teams building DIMM assemblies or server memory modules should include this lead time in their production planning, particularly for volume orders. Stocking safety inventory equivalent to at least one full production cycle is advisable to avoid line stoppages when demand for DDR memory modules increases unexpectedly.
