2 UART (16C550 compatible) BIOS AMI Aptio ® V UEFI 2.x firmware 32 MB serial SPI flash with congatec Embedded BIOS features Power ACPI 4.0a compliant with battery support. S5e mode (see section 7.1.7 “Enhanced Soft-Off State” ) Management Deep Sx and Suspend to RAM (S3)
Power Consumption The power consumption values were measured with the following setup: • Input voltage +12 V • conga-TC370 COM • Modified congatec carrier board • conga-TC370 cooling solution • Microsoft Windows 10 (64 bit) Note The CPU was stressed to its maximum workload with the Intel ®...
Storage: 5% to 95% Caution The above operating temperatures must be strictly adhered to at all times. When using a congatec heatspreader, the maximum operating temperature refers to any measurable spot on the heatspreader’s surface. Humidity specifications are for non-condensing conditions.
1. We recommend a maximum torque of 0.4 Nm for carrier board mounting screws and 0.5 Nm for module mounting screws. 2. The gap pad material used on congatec heatspreaders may contain silicon oil that can seep out over time depending on the environmental conditions it is subjected to.
PCI Express Graphics (PEG) The conga-TC370 supports an optional x1 or x2 PEG port on the C–D connector. To support this optional interface, you need a customized conga-TC370 variant. For more information, contact congatec technical support team. Note The PEG lanes can not be linked together with the PCI Express lanes in section 6.1.1 “PCI Express™”.
The USB ports are configured in the BIOS setup menu to operate by default in Gen 1 mode. Before you change the default setting to Gen 2, ensure the carrier board is designed for Gen 2 operation. For Gen 2 design considerations, contact congatec technical support center.
10.1.1 “LPC Bus”. 6.1.11 I²C Bus The I²C bus is implemented through the congatec board controller and accessed through the congatec CGOS driver and API. The controller provides a fast-mode multi-master I²C bus that has the maximum I²C bandwidth. 6.1.12 General Purpose Serial Interface The conga-TC370 offers two standard 16C550 UARTs on the A–B connector via the congatec Board Controller.
6.1.13 GPIOs The conga-TC370 offers General Purpose Input/Output signals on the A–B connector. The GPIO signals are controlled by the congatec Board controller. 6.1.14 Power Control PWR_OK Power OK from main power supply or carrier board voltage regulator circuitry. A high value indicates that the power is good and the module can start its onboard power sequencing.

0.8 V when the 12 V is applied to the module. Actively driving PWR_OK high is compliant to the COM Express specification but this can cause back driving. Therefore, congatec recommends driving the PWR_OK low to keep the module in reset and tri-state PWR_OK when the carrier board hardware is ready to boot.
Board Controller (cBC) The conga-TC370 is equipped with Microchip 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.
Enhanced Soft-Off State The conga-TC370 supports an enhanced Soft-Off state (S5e)—a congatec proprietary low-power Soft-Off state. In this state, the CPU module switches off almost all the onboard logic in order to reduce the power consumption to absolute minimum (between 0.05 mA and 0.09 mA).
OEM POST Logo This feature allows system designers to replace the congatec POST logo displayed in the upper left corner of the screen during BIOS POST with their own BIOS POST logo. Use the congatec system utility CGUTIL 1.5.4 or later to replace/add the OEM POST logo.
OEM BIOS Code/Data With the congatec embedded BIOS it is possible for system designers to add their own code to the BIOS POST process. The congatec Embedded BIOS first calls the OEM code before handing over control to the OS loader.
The architecture of the CGOS API driver provides the ability to write application software that runs unmodified on all congatec CPU modules. All the hardware related code is contained within the congatec embedded BIOS on the module. See section 1.1 of the CGOS API software developers guide, available on the congatec website.
See section 8.1 “Adaptive Thermal Monitor and Catastrophic Thermal Protection” for more information. The congatec board controller supports active cooling solution. The board controller controls the fan’s speed based on the temperature readings of the CPU. This feature does not require ACPI OS support. The only software-controlled thermal trip point on conga-TC370 is the Critical Trip Point.
The table below describes the terminology used in this section. The PU/PD column indicates if a pull-up or pull-down resistor has been used. If the field entry area in this column for the signal is empty, then no pull-up or pull-down resistor has been implemented by congatec. The “#”...
On the conga-TC370, the PCI Express Bus acts as the subtractive decoding agent. All I/O cycles that are not positively decoded are forwarded to the PCI Bus not the LPC Bus. Only specified I/O ranges are forwarded to the LPC Bus. In the congatec Embedded BIOS the following I/O address ranges are sent to the LPC Bus: 2Eh –...
4. Internal PCI devices not connected to the conga-TC370 are not listed. 10.3 Onboard resources are not connected to the I²C bus. Address 16h is reserved for congatec Battery Management solutions. 10.4 SM Bus System Management (SM) bus signals are connected to the Intel ®...
Navigating the BIOS Setup Menu The BIOS setup menu shows the features and options supported in the congatec BIOS. To access and navigate the BIOS setup menu, press the <DEL> or <F2> key during POST. The right frame displays the key legend. Above the key legend is an area reserved for text messages. These text messages explain the options and the possible impacts when changing the selected option in the left frame.
BIOS updates are recommeded to correct platform issues or enhance the feature set of the module. The conga-TC370 features a congatec/AMI AptioEFI firmware on an onboard flash ROM chip. You can update the firmware with the congatec System Utility. The utility has five versions—...
