Case Open Intrusion Connector

The conga-IA5 provides connector X23 for case-open intrusion detection.
Table 39 Case Open Intrusion (Connector X23) Pinout Description
Pin Function
1 GND
2 CASEOPEN#
Connector Type
X23: 2.54mm, 1x2 pin header
6.3 Trusted Platform Module – TPM (Optional)
Optionally, the conga-IA5 SBC can be equipped with a TPM 1.2/2.0 compliant security chip. The TPM security chip is connected to the LPC
bus provided by the integrated Intel

congatec Board Controller (cBC)

The conga-IA5 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-IA5 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
revolution in order to produce an accurate reading. For this reason, a two pulse per revolution fan or similar hardware solution is recommended.
