1 OVERVIEW
The onboard System Management Controller (SMC) on many Lippert Boards 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 permitting the user to:
• Set/Clear the Watchdog-timer
• Read the uptime seconds since power on
• Read the total ontime minutes
• Read the power cycles
• Read the current temperature of the CPU and Board
• Get PowerUp-Temperature of CPU and Board
• Min-/Max-Temperature Logger of CPU and Board
• Read Onboard-Voltages
• Read current drawn by the board
• Control the Backlight of the LVDS
• Get Fan-Speed
• Get access to 512 / 1024 Bytes of Flash-ROM for User data
• Save Data in 128 Bytes of Write-Protectable Flash-ROM (fused)
• Read the version information of the SMC Firmware
• Get the status information of the SMC
