MCP98243T-BE/MNY

Overview

The MCP98243T-BE/MNY 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 voltage range of 1.8V to 5.5V, with a specified range of 3.0V to 3.6V for the sensor. It provides accuracy of ±0.2°C/±1°C (typ./max.) from +75°C to +95°C and ±1°C/±3°C (typ./max.) from -20°C to +125°C. The package is an 8-pin TDFN.

Feature Summary

Integrated 2 Kbit Serial EEPROM for DIMM vendor information storage
User-programmable registers for shutdown modes and event boundaries
Open-drain Event output for thermostat or interrupt operations
Permanent and reversible software write protection capabilities

Applications

DIMM modules for servers, PCs, and laptops
General purpose temperature datalogging

Procurement Notes

Verify the specific suffix MNY confirms the TDFN-8 package type. Confirm the BE grade matches required accuracy specifications. Ensure the component status is reviewed as availability may vary.

Selection Notes

Select this part when JEDEC compliance and SPD data storage are required. Consider the operating voltage range and thermal resistance characteristics for the target PCB layout.

Part Context

This component belongs to the MCP9843/98243 family of memory module thermal sensors. It shares the core sensing architecture with the MCP9843 but adds non-volatile memory specifically designed for DRAM DIMM applications.

Replacement Considerations

The MCP9843 serves as a functional substitute if EEPROM storage is not required. Verify pin compatibility and register mapping differences before substitution.
