Chapter 1 About This Manual This manual provides information about the components, features, connectors and BIOS Setup menus available on the COM 830. Symbols The following symbols are used in this manual: Warning Warnings indicate conditions that, if not observed, can cause personal injury. Caution Cautions warn the user about how to prevent damage to hardware or loss of data.
Chapter 1 About This Manual Beginning on the date of shipment to its direct customer and continuing for the published warranty period, Ampro represents that the products are new and warrants that each product failing to function properly under normal use, due to a defect in materials or workmanship or due to non conformance to the agreed upon specifications, will be repaired or exchanged, at Ampro's option and expense.
Chapter 1 About This Manual Carrier board designers can utilize as little or as many of the I/O interfaces as necessary. The carrier board can therefore provide all the interface connectors required to attach the system to the application specific peripherals.

Chapter 2 Specifications Electrostatic Sensitive Device All COM 830 variants are electrostatic sensitive devices. Do not handle the COM 830, or processor, except at an electrostatic-free workstation. Failure to do so may cause damage to the module and/or processor and void the manufacturer’s warranty.
Chapter 2 Specifications Windows XP Professional Standby Mode (requires setup node “Suspend Mode” in the BIOS to be configured to S1 POS [Power On Suspend]) Suspend to RAM (requires setup node “Suspend Mode” in BIOS to be configured to S3 STR [suspend to RAM]) NOTE The PassMark, Burn-In Test-Suite was used to stress the CPU to 100% workload.

Chapter 2 Specifications 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.
Chapter 2 Specifications Heatspreader Dimensions Heatspreader is available for all variants of COM 830. NOTE All measurements are in millimeters. Torque specification for heatspreader screws is 0.5 Reference Manual COM 830...
Chapter 2 Specifications Connector Subsystems Rows A, B, C, D The COM 830 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.
Chapter 2 Specifications PCI Express™ The COM 830 offers 6x x1 PCI Express lanes via the Intel 82801GHM (ICH7M-DH), which can be configured to support PCI Express edge cards or ExpressCards. One of the six x1 PCI Express lane is utilized by the onboard Ethernet controller therefore there are only 5x x1 PCI Express lanes available on the A,B connector row.
Chapter 2 Specifications Power Supply Implementation Guidelines 12 volt input power is the sole operational power source for the COM 830. The remaining necessary voltages are internally generated on the module using onboard voltage regulators. A baseboard designer should be aware of the following important information when designing a power supply for a COM 830 application: It has also been noticed that on some occasions problems occur when using a 12V power supply that produces non monotonic voltage when powered up.
Chapter 2 Specifications Onboard Microcontroller The COM 830 is equipped with an ATMEL Atmega168 microcontroller. This onboard microcontroller plays an important role for most of the 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.
Chapter 2 Specifications Simplified Overview of BIOS Setup Data Backup Ampro Ampro The above diagram provides an overview of how the BIOS Setup Data is backed up on modules. OEM default values mentioned above refer to customer specific CMOS settings created using the System Utility tool.
Chapter 2 Specifications Security Features The COM 830 can be equipped optionally with a “Trusted Platform Module” (TPM 1.2). This TPM 1.2 includes co-processors to calculate efficient hash and RSA algorithms with key lengths up to 2,048 bits as well as a real random number generator. Security sensitive applications like gaming and e-commerce will benefit also with improved authentication, integrity and confidence levels.
Chapter 2 Specifications Native vs. Compatible IDE mode Compatible Mode When operating in compatible mode, the SATA and PATA (Parallel ATA) controller together need two legacy IRQs (14 and 15) and are unable to share these IRQs with other devices. This is a result of the fact that the SATA and PATA controller emulate legacy IDE controllers.
Chapter 2 Specifications 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.
Chapter 2 Specifications 64-bit Mode: 64-bit operating system and 64-bit applications. This usage requires 64-bit device drivers. It also requires applications to be modified for 64-bit operation and then recompiled and validated. Intel 64 provides support for: 64-bit flat virtual address space 64-bit pointers 64-bit wide general purpose registers 64-bit integer support...
Chapter 2 Specifications Active Cooling During this cooling policy the operating system is turning the fan on/off. Although active cooling devices consume power and produce noise, they also have the ability to cool the thermal zone without having to reduce the overall system performance. Use the “active cooling trip point” setup node in the BIOS setup program to determine the temperature threshold that the operating system will use to start the active cooling device.

Chapter 2 Specifications 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).
