Trusted Platform Module – TPM (Optional)
The conga-IA4 SBC can optionally be equipped with a TPM 1.2 compliant security chip. The TPM security chip is connected to the LPC bus
provided by the integrated Intel Chipset. The basic TPM chip initialization is performed by the SBC’s UEFI Boot firmware.
Note
The TPM feature is not available by default. You need a customized variant for TPM support.

congatec Board Controller (cBC)
The conga-IA4 is equipped with a Texas Instruments Tiva™ TM4E1231H6ZRBI microcontroller. This onboard microcontroller plays an important
role for most of the congatec BIOS features. It fully isolates some of the embedded features such as system monitoring or the I²C bus from
the x86 core architecture, which results in higher embedded feature performance and more reliability, even when the x86 processor is in a low
power mode.

Fan Control
The conga-IA4 has additional signals and functions to further improve system management. One of these signals is an output signal called
FAN_PWMOUT that allows system fan control using a PWM (Pulse Width Modulation) output. Additionally, there is an input signal called
FAN_TACHOIN that provides the ability to monitor the system’s fan RPMs (revolutions per minute). This signal must receive two pulses per
