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.
