The Microchip Technology MCP98243-BE/MC is a digital temperature sensor designed for accurate temperature monitoring. It converts temperature readings from -40°C to +125°C into a digital word, meeting JEDEC specifications for memory module thermal sensing.
This sensor features a 2-wire I2C/SMBus interface, allowing communication with microcontrollers. It provides a typical operating current of 200 µA and offers sensor accuracy of ±0.2°C/±1°C from +75°C to +95°C, with wider ranges available at different temperatures. The MCP98243 variant includes a 2 Kbit Serial EEPROM for storing memory module and vendor information, with options for permanent and reversible software write protection.
Available in an 8-DFN (2x3) package, the MCP98243-BE/MC is suitable for surface mount applications. It includes user-programmable registers for settings like shutdown or low-power modes and temperature event boundaries, outputting an alert signal when limits are exceeded. This makes it ideal for applications such as DIMM modules for servers, PCs, and laptops, as well as general-purpose temperature data logging.
