The LPC47M192 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant Super I/O controller with an LPC interface and Hardware Monitoring capabilities.
The LPC47M192’s hardware monitoring capability includes voltage and temperature monitoring with the ability to alert the system of out-of-limit conditions. There are 7 analog inputs for monitoring external voltages of +1.5V, +1.8V, +2.5V, +3.3V, +5V, +12V and Vccp (core processor voltage), as well as internal monitoring of the devices own HVCC or HVSB. The LPC47M192 includes support for monitoring two external temperatures via thermal diode inputs and an internal sensor for measuring ambient temperature. The nTHERM pin is implemented to indicate out-of-limit temperature and voltage conditions. The block has an ability to output 20ms low pulse via nRESET pin. The hardware monitoring block of the LPC47M192 is accessible via the System Management Bus (SMBus).
