The Microchip Technology MCP98243T-BE/MC is a digital temperature sensor designed for precise 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 and other devices on a shared bus. The MCP98243 variant includes a 2 Kbit Serial EEPROM, organized as 256 x 8-bit, which is ideal for storing memory module and vendor information, particularly for DIMM modules in servers, PCs, and laptops. The EEPROM supports permanent and reversible software write protection for critical data.
Key specifications include an operating voltage range of 2.7V to 5.5V and a typical operating current of 200 µA. The sensor provides an accuracy of ±3°C maximum across its operating range. It is available in an 8-VFDFN Exposed Pad package and is designed for surface mount applications.
User-programmable registers offer flexibility for applications, allowing settings for shutdown or low-power modes and user-defined temperature event boundaries. An Alert output signal can indicate when temperature limits are exceeded, configurable as an active-low or active-high comparator output or as a temperature event interrupt.
