5. Smart Embedded Management Agent (SEMA)

The onboard microcontroller (BMC) implements power sequencing and Smart Embedded Management Agent (SEMA) functionality.

The microcontroller communicates via the System Management Bus with the CPU/chipset.

The following functions are implemented

¾ Total operating hours counter. Counts the number of hours the module has been run in minutes.

¾ On-time minutes counter. Counts the seconds since last system start.

¾ Temperature monitoring of CPU and board temperature. Minimum and maximum temperature values of CPU and board are stored in

flash.

¾ Power cycles counter

¾ Boot counter. Counts the number of boot attempts.

¾ Watchdog Timer (Type-II). Set / Reset / Disable Watchdog Timer. Features auto-reload at power-up.

¾ System Restart Cause. Power loss / BIOS Fail / Watchdog / Internal Reset / External Reset

¾ Fail-safe BIOS support. In case of a boot failure, hardware signals tells external logic to boot from fail-safe BIOS.

¾ Flash area. 1kB Flash area for customer data

¾ 128 Bytes Protected Flash area. Keys, IDs, etc. can be stored in a write- and clear-protectable region.

¾ Board Identify. Vendor / Board / Serial number / Production Date

¾ Main-current & voltage. Monitors drawn current and main voltages

For a detailed description of SEMA features and functionality, please refer to the SEMA Technical Manual and SEMA Software Manual,

Note: Due to limitations of the Intel “Bay Trail” platform, SEMA can only obtain CPU temperature readings when the OS is running.
