MCP98243-BE/MC

Overview

The MCP98243-BE/MC is a digital temperature sensor with an integrated 2 Kbit Serial EEPROM for SPD. It meets JEDEC JC42.4-TSE2002B3 specifications. The device converts temperatures from -40°C to +125°C using a Delta-Sigma ADC. Grade B accuracy is ±0.2°C/±1°C (typ./max.) from +75°C to +95°C, and ±0.5°C/±2°C from +40°C to +125°C. The specified VDD range is 3.0V to 3.6V, while the operating range is 2.7V to 5.5V. Typical operating current is 200 µA. The I2C interface supports up to 400 kHz.

Feature Summary

Integrates a 2 Kbit Serial EEPROM organized as 256 x 8-bit for storing memory module and vendor information.
Features user-programmable registers allowing selectable shutdown modes and temperature event boundaries.
Provides an open-drain Event output configurable as an active-low/high comparator or interrupt signal.
Includes permanent and reversible software write protection capabilities for data security.

Applications

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

Procurement Notes

Verify that the ordering suffix /MC corresponds to the DFN-8 package type as documented in the official datasheet. Confirm that the specific grade B accuracy requirements align with the JEDEC JC42.4-TSE2002B3 specification limits provided in the electrical characteristics tables. Ensure voltage levels at address pins meet the high-voltage input requirements if write protection features are utilized.

Selection Notes

Select this component when SPD storage is required alongside thermal monitoring on memory modules. The device supports standard I2C communication protocols compatible with SMBus systems. Consider the thermal resistance values of the DFN-8 package for PCB layout optimization. Verify that the host controller can support the required I2C bus frequency and timeout ranges defined in the timing specifications.

Part Context

This part belongs to the MCP9843/98243 family of digital temperature sensors manufactured by Microchip Technology. The MCP98243 variant specifically includes the onboard EEPROM functionality absent in the MCP9843 model. Both devices share identical thermal sensing architectures and interface protocols, differing primarily in data storage capacity and SPD compliance.
