SECTION 1: OVERVIEW
The MAX31782 system management microcontroller provides a complete solution for the monitoring and controlling
of complex system physical health characteristics . The MAX31782 is based on the high-performance 16-bit family of
MAXQM reduced instruction set computing (RISC) microcontrollers . The MAX31782 provides generous amounts of
flash program memory and SRAM data memory .
