1.5 Power Consumption The power consumption values listed in this document were measured under a controlled environment. The hardware used includes a conga‑B915 module, conga-CEVAL and conga-Cdebug carrier boards, CRT monitor, SATA drive, and USB keyboard. When using the conga‑Cdebug, the SATA drive was powered externally by an ATX power supply so that it does not influence the power consumption value that is measured for the module.
Processor Information In the following power tables there is some additional information about the processors. Intel® offers processors that are considered to be low power consuming. These processors can be identified by their voltage status. Intel uses the following terms to describe these processors. If none of these terms are used then the processor is not considered to be low power consuming.

3 Heatspreader An important factor for each system integration is the thermal design. The heatspreader acts as a thermal coupling device to the module. It is a 3mm thick aluminum plate. The heatspreader is thermally coupled to the CPU via a thermal gap filler and on some modules it may also be thermally coupled to other heat generating components with the use of additional thermal gap fillers.
3.1 Heatspreader Dimensions Bottom side view Note All measurements are in millimeters. Torque specification for heatspreader screws is 0.5 Nm.
4 Connector Subsystems Rows A, B, C, D The conga-B915 is connected to the carrier board via two 220-pin connectors (COM Express Type 2 pinout) for a total of 440 pins connectivity. These connectors are broken down into four rows. The primary connector consists of rows A and B while the secondary connector consists of rows C and D. C-D x16 PCI Express Graphics A-B 3x x1 PCI Express Lanes (only available on 82915GME variants) 2x Serial ATA 2x SDVO 8x USB 2.
4.1 Primary Connector Rows A and B The following subsystems can be found on the primary connector rows A and B. 4.1.1 Serial ATA™ (SATA) Two Serial ATA150 connections are provided via the Intel® 82801FBM (ICH6M). SATA is an enhancement of the parallel ATA therefore offering higher performance. As a result of this enhancement the traditional restrictions of parallel ATA are overcome with respect to speed and EMI.
4.1.5 LPC Bus conga-B915 offers the LPC (Low Pin Count) bus through the use of the Intel® 82801FBM (ICH6M). There are already many devices available for this Intel defined bus. The LPC bus corresponds approximately to a serialized ISA bus yet with a significantly reduced number of signals. Due to the software compatibility to the ISA bus, I/O extensions such as additional serial ports can be easily implemented on an application specific baseboard using this bus. See section 8.2.
4.1.11 Power Control PWR_OK Power OK from main power supply. A high value indicates that the power is good. Using this input is optional. Through the use of an internal monitor on the +12V ± 5% input voltage and/or the internal power supplies the conga‑B915 module is capable of generating its own power-on reset. According to the COM Express™ Specification PWR_OK is a 3.3V signal. The conga-B915 provides support for controlling ATX-style power supplies.
4.1.12 Power Management APM 1.2 compliant. ACPI 2.0 compliant with battery support. Also supports Suspend to RAM (S3). 4.2 Secondary Connector Rows C and D The following subsystems can be found on the secondary connector rows C and D. 4.2.1 PCI Express Graphics (PEG) conga-B915 variants equipped the Intel® 82915GME chipset support the implementation of a x16 link for an external high-performance PCI Express Graphics card. These modules support a theoretical bandwidth of up to 4GB/s (unidirectional).
5 Additional Features 5.1 Watchdog The conga-B915 is equipped with a multi stage watchdog solution that is triggered by software. The COM Express™ Specification does not provide support for external hardware triggering of the Watchdog, which means the conga-B915 does not support external hardware triggering. For more information about the Watchdog feature see the BIOS setup description section 9.4.13 of this document and application note AN3_Watchdog.pdf on the congatec AG website at www.congatec.com.
5.3.
Once the BIOS Setup Program has been entered and the settings have been changed, the user saves the settings and exits the BIOS Setup Program using the F10 key feature. After the F10 function has been evoked, the CMOS Data is stored in a dedicated non‑volatile CMOS Data Backup area located in the BIOS Flash Memory chip as well as RTC. The CMOS Data is written to and read back from the CMOS Data Backup area and verified.
6 conga Tech Notes The conga-B915 has some technological features that require additional explanation. The following section will give the reader a better understanding of some of these features. This information will also help to gain a better understanding of the information found in the System Resources section of this user’s guide as well as some of the setup nodes found in the BIOS Setup Program description section. 6.
interrupt for both channels and also has the ability to share this interrupt with other devices in the system. Setting Enhanced mode in the BIOS setup program will automatically enable Native mode as Native mode is a subset of Enhanced mode. See section 9.4.8 for more information about this. Running in native mode frees up interrupt resources (IRQs 14 and 15) and decreases the chance that there may be a shortage of interrupts when installing devices.
prevent any damage to the processor as a result of overheating. The THERMTRIP# signal activation is completely independent from processor activity and therefore does not produce any bus cycles. Note In order for THERMTRIP# to be able to automatically switch off the system it is necessary to use an ATX style power supply. 6.3.
off interval ratio. This means that when set to 75% the clock is running 75% of the overall time and this leads to a performance decrease of approximately 25%. 6.4 Thermal Management ACPI is responsible for allowing the operating system to play an important part in the system’s thermal management. This results in the operating system having the ability to take control of the operating environment by implementing cooling decisions according to the demands put on the CPU by the application.
Note The end user must determine the cooling preferences for the system by using the setup nodes in the BIOS setup program to establish the appropriate trip points. If passive cooling is activated and the processor temperature is above the trip point the processor clock is throttled according to the formula below.
The following table lists the “Wake Events” that resume the system from both S1 or S3 unless otherwise stated in the “Conditions/Remarks” column: Wake Event Power Button Onboard LAN Event SMBALERT# PCI Express WAKE# PME# Conditions/Remarks Wakes unconditionally from S1-S5. Device driver must be configured for Wake On LAN support. Wakes unconditionally from S1-S5. Wakes unconditionally from S1-S3.
6.6 USB 2.0 EHCI Host Controller Support The 8 USB ports are shared between an EHCI host controller and the 4 UHCI host controllers. Within the EHC functionality there is a port-routing logic that executes the mixing between the two different types of host controllers (EHCI and UHCI). This means that when a USB device is connected the routing logic determines who owns the port. If the device is not USB 2.

10 Additional BIOS Features The conga-B915 uses a congatec/AMIBIOS that is stored in an onboard Flash Rom chip and can be updated using the congatec System Utility, which is available in a DOS based command line, Win32 command line, Win32 GUI, and Linux version. The BIOS displays a message during POST and on the main setup screen identifying the BIOS project name and a revision code.
10.2.2 BIOS Recovery via Serial Port The Serial Flash method allows for boot block recovery by loading a BIOS image via a serial port (COM1). This is can be used by many headless embedded systems which rely on a serial port as a debug and utility console port. This feature is disabled by default. See setup node in the “BIOS Setup Description” section 9.4.11 “Remote Access Configuration Submenu”. For more information about “BIOS Recovery via Serial Port” refer to application note AN6_BIOS_Recovery.
10.5 Hard Disk Security Features Hard Disk Security uses the Security Mode feature commands defined in the ATA specification. This functionality allows users to protect data using drive-level passwords. The passwords are kept within the drive, so data is protected even if the drive is moved to another computer system. The BIOS provides the ability to ‘lock’ and ‘unlock’ drives using the security password. A ‘locked’ drive will be detected by the system, but no data can be accessed.
