The Microchip Technology MCP98243T-BE/MNYAA is a digital temperature sensor designed for temperature monitoring systems, particularly in DIMM modules for servers, PCs, and laptops. It converts temperature readings from -40°C to +125°C into a digital word.
This sensor features a 2-wire I2C/SMBus interface, allowing for easy integration into various systems. It meets JEDEC specifications for memory module thermal sensors. The MCP98243 variant includes a 2 Kbit Serial EEPROM, organized as 256 x 8-bit, which can store memory module and vendor information. This EEPROM supports permanent and reversible software write protection for the lower 1 Kbit.
The device operates within a voltage range of 2.7V to 5.5V. It offers user-programmable registers for settings like shutdown or low-power modes and temperature event boundaries, triggering an alert signal when limits are exceeded. The sensor is available in an 8-WFDFN Exposed Pad package and is designed for surface mount applications.
Key specifications include a typical operating current of 200 µA for the temperature sensor and accuracy ratings such as ±0.2°C/±1°C (typ./max.) from +75°C to +95°C. The EEPROM has separate operating voltage and current specifications.
