MAX31782
System Management Microcontroller
19-5327; Rev 2; 1/12
Typical Operating Circuit appears at end of data sheet.
General Description
The MAX31782 provides a complete solution for the
monitoring and controlling of complex 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 sys-
tem for temperature and voltage, PWM outputs, timer
inputs, and GPIO to support monitoring and controlling
critical system parameters such as temperature, volt-
age, fan speed, and chassis intrusion. Direct connection
of diode-connected transistors used as remote tem-
perature 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 communica-
tion to a host microprocessor in addition to password-
protected in-system reprogramming of the on-chip flash.
Ease of development is supported with highly versatile
C-compilers and development software that programs
flash and performs in-circuit debug through the inte-
grated JTAG interface and associated hardware.
All these features combined make the device a highly
flexible platform, allowing the designer to easily create a
customized complex system management solution.
