MCP98243T-BE/MUYAA

Thermal Management Overview

The MCP98243T-BE/MUYAA is a digital temperature sensor with an integrated 2 Kbit Serial EEPROM for SPD. It meets JEDEC JC42.4-TSE2002B3 specifications and features a 2-wire I²C/SMBus interface. The device operates within a -40°C to +125°C range, offering ±0.2°C typical accuracy from +75°C to +95°C. Supply voltage ranges from 1.8V to 5.5V, with typical operating currents of 200 µA for the sensor and 100 µA for EEPROM reads.

Thermal Management Feature Summary

• Integrated 2 Kbit EEPROM supports Serial Presence Detect (SPD) data storage
• Compliant with JEDEC JC42.4-TSE2002B3 Memory Module Thermal Sensor Component standard
• Features user-programmable temperature event boundaries and alert outputs
• Includes permanent and reversible software write protection for memory data

Thermal Management Applications

• DIMM modules for servers, PCs, and laptops
• General purpose temperature datalogging
• DRAM vendor and product information storage

Thermal Management Procurement Notes

Verify the specific suffix MUYAA against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with the required JEDEC specification level. Confirm that the ordering code matches the exact electrical characteristics and pinout defined in the datasheet before finalizing procurement.

Thermal Management Selection Notes

Select this component when JEDEC compliance and onboard SPD storage are required. The device provides high accuracy in critical temperature ranges and supports multiple address configurations via hardware pins. Consider the exposed thermal pad for improved heat dissipation in dense PCB layouts.

Thermal Management Part Context

This part belongs to the MCP9843/98243 family of digital temperature sensors manufactured by Microchip Technology. The MCP98243 variant specifically includes the EEPROM functionality absent in the MCP9843 model. It is designed for applications requiring precise thermal monitoring alongside memory module identification.

Thermal Management Replacement Considerations

The MCP98242 is a comparable part within the same family but lacks the EEPROM feature and has different I2C timing specifications.
