4.3 LEMT Functions

The onboard Microcontroller implements power sequencing and LEMT (LiPPERT Enhanced

Management Technology) functionality. The microcontroller communicates via the System

Management Bus with the CPU/Chipset. The following functions are implemented:

• Total operating hours counter

Counts the number of hours the module has been run in minutes.

• On-time minutes counter

Counts the seconds since last system start.

• Temperature monitoring of CPU and Board temperature

Min. and max. temperature values of CPU and board are stored in flash.

• Power cycles counter

• Watchdog Timer

Set / Reset / Disable Watchdog Timer.

• System Restart Cause

Power loss / Watchdog / External Reset.

• Fail-Safe-BIOS Support

In case of a Boot failure, hardware signals tells external logic to boot from a Fail-Safe-BIOS.

• Flash area

1kB Flash area for customer data

• Protected Flash area

128 Bytes for Keys, ID's, etc. can stored in a write- and clear-protectable region.

• Manufacturing information

Part number / Serial number / BIOS version / Test date

• Current Power consumption and average

Please refer to the LEMT documentation for the usage of the LEMT functions.
