MCP98242T-BE/MNY

Thermal Management Overview

The MCP98242T-BE/MNY is a digital temperature sensor with an integrated 256-byte Serial EEPROM designed for JEDEC DIMM applications. It operates within a voltage range of 3.0V to 3.6V and features an I2C/SMBus interface. The device provides high accuracy, specified as ±0.5°C typical and ±1°C maximum between +75°C and +95°C. It includes user-programmable registers for shutdown modes, hysteresis, and event output boundaries.

Thermal Management Feature Summary

• Integrates a digital temperature sensor with a 256-byte Serial EEPROM specifically organized for DRAM DIMM Serial Presence Detect (SPD) data storage.
• Features a 2-wire I2C/SMBus compatible serial interface allowing multiple devices on a single bus with configurable address pins.
• Includes user-programmable registers for configuring shutdown modes, temperature boundary trip limits, and event output polarity.

Thermal Management Applications

• JEDEC Mobile Platform Memory Module Thermal Sensor Component
• DRAM DIMM Modules
• Laptops, Personal Computers and Servers

Thermal Management Procurement Notes

Verify the specific suffix MNY against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required operating voltage range of 3.0V to 3.6V for proper interface functionality. Confirm that the exposed thermal pad connection requirements are met in the PCB layout design.

Thermal Management Selection Notes

Select this component when JEDEC JC42.4 compliance is required for memory module thermal monitoring. The integrated EEPROM simplifies system design by storing vendor information directly on the module. Consider the ±0.5°C accuracy specification for critical thermal management applications within the active temperature range.

Thermal Management Part Context

This device belongs to the MCP98242 family of digital temperature sensors manufactured by Microchip Technology. It is part of a series optimized for mobile platform memory modules, combining precise thermal sensing with non-volatile storage capabilities in a compact surface-mount package.

Thermal Management Replacement Considerations

Check for MCP98242 variants with different package options such as TSSOP-8 or DFN-8 if pin compatibility differs. Verify electrical characteristics match the 3.0V to 3.6V operating range. Ensure the replacement maintains the same I2C/SMBus protocol support and EEPROM capacity.
