MCP98243T-BE/MNYAB

Overview

The MCP98243T-BE/MNYAB 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 Grade B accuracy of ±0.2°C/±1°C (typ./max.) from +75°C to +95°C. It supports user-programmable registers for shutdown modes and event boundaries. The EEPROM allows permanent or reversible software write protection for vendor data storage.

Feature Summary

• Integrates a 2 Kbit Serial EEPROM specifically designed for DRAM DIMM Serial Presence Detect applications.
• Provides high-precision temperature sensing with Grade B accuracy meeting JEDEC thermal sensor component standards.
• Features user-configurable Event output pins supporting active-low or active-high thermostat and interrupt operations.

Applications

• DIMM Modules for Servers
• DIMM Modules for PCs
• DIMM Modules for Laptops

Procurement Notes

Verify the specific suffix 'MNYAB' against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with the specified VDD operating ranges for both the sensor and EEPROM functions before integration into the design.

Selection Notes

Select this component when JEDEC JC42.4 compliance and onboard SPD memory are required. It is suitable for systems needing programmable thermal alerts and precise monitoring in compact surface-mount packages.

Part Context

This part belongs to the MCP9843/98243 family of digital temperature sensors. Unlike the MCP9843, the MCP98243 variant includes non-volatile memory for storing module information, making it distinct for memory module applications.

Replacement Considerations

Public confirmed substitute: MCP98242T-BE/MUYAB.
