MAX31782 Datasheet | Maxim Integrated

Description The MAX31782 provides a plete solution for the monitoring and controlling of plex system physical health characteristics based on a high-performance, MAXQ20, 16-bit microcontroller core with generous amounts of flash program/data and RAM data memory. I/O resources include an accurate measurement system for temperature and voltage, PWM outputs, timer inputs, and GPIO to support monitoring and controlling critical system parameters such as temperature, voltage, fan speed, and chassis intrusion. Direct connection of diode-connected transistors used as remote temperature sensors is supported as well as expansion to a virtually unlimited number of external digital temperature sensor ICs using the on-chip master I2C interface. An independent slave I2C interface facilitates munication to a host microprocessor in addition to passwordprotected in-system reprogramming of the on-chip flash. Ease of development is supported with highly versatile C-pilers and development software that programs flash and performs in-circuit debug through the integrated JTAG interface and associated hardware. All these features bined make the device a highly flexible platform, allowing the designer to easily create a customized plex system management solution.
