5 Additional Features

5.1 congatec Board Controller (cBC)

The conga-TCA is equipped with a STMicroelectronics STM32 microcontroller. This onboard microcontroller plays an important role for most of

the congatec embedded/industrial PC 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. It also ensures that the congatec embedded feature set is fully compatible amongst all congatec modules.

5.2 Board Information

The cBC provides a rich data-set of manufacturing and board information such as serial number, EAN number, hardware and rmware

revisions, and so on. It also keeps track of dynamically changing data like runtime meter and boot counter.

5.3 Watchdog

The conga-TCA is equipped with a multi stage watchdog solution that is triggered by software. The COM Express™ Specication does

not provide support for external hardware triggering of the Watchdog, which means the conga-TCA does not support external hardware

triggering. For more information about the Watchdog feature see the BIOS setup description section 9.4.2 of this document and application

note AN3_Watchdog.pdf on the congatec AG website at www.congatec.com.

Note

The conga-TCA module does not support the watchdog NMI mode. COM Express type 6 modules do not support the PCI bus and therefore the

PCI_SERR# signal is not available. There is no way to drive a NMI to the processor without the presence of the PCI_SERR# PCI bus signal.

5.4 I

C Bus

The conga-TCA offers support for the frequently used I

C bus. Thanks to the I

C host controller in the cBC the I

C bus is multimaster capable

and runs at fast mode.
