ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

Type 2 Basic Module
Chapter 1
Introduction
TM
The CEM100 is a new COM Express Type 2 Basic Module to support BGA type AMD
G-Series processors. It integrates AMD FCH A55E chipset which supports the most updated
high speed I/O, like PCI-Express gen 2 at 5GT/s and SATA-600 at 6Gb/s. The CEM100 does
TM
fully comply with COM Express Type 2 specification. It provides 8 lanes of PCIe, gigabit
ethernet, HD audio interface, VGA/LVDS LCD and 2 configurable digital display ports for more
flexible digital display options.

Specifications
CPU
AMD G-Series BGA processors.
Chipset
AMD FCH A55E chipset.
BIOS
American Megatrends Inc. BIOS.
16Mbit SPI Flash, DMI, Plug and Play.
RPL/PXE Ethernet Boot ROM, customized default saving features, LPC-free
supported, uses SPI type flash memory.
System Memory
Two 204-pin DDR3 SO-DIMM slots.
Maximum up to 8GB DDR3 1066MHz memory.
TPM
Trusted Platform Module compatible with TPM1.2 Main and PC Client specification
based on AMD LPC Bus Interface.
Expansion Interface
Four PCI-Express x1 (gen 2) thru APU for discrete graphics or general purpose PCI
Express (1 x4 or 4 x1).
Four PCI-Express x1 (gen 2) thru FCH general purpose PCI Express.
USB Interface
Eight USB ports comply with USB Spec. Rev. 2.0.
SATA Interface
TM
Four SATA 6Gb/s ports supported through COM Express connector.
Note: Users upgrading a computer system with a larger hard disk drive may have problems
using more than 2.2 terabytes (TB) of disk space. This size limit is based on limits
introduced by the master boot record (MBR) partitioning method.
Users can install the OS on a MBR formatted disk under 2.2TB. The OS will use the
MBR disk as the boot drive, eliminating the MBR limitation.
Video
ATi Radeon HD6310/HD6250 integrated in APU T56N/T40R.
CRT interface supports up to QXGA (2048 x 1536).
18/24-bit single/dual channel LVDS interface.

Installing Heat spreader
For thermal dissipation, a heat spreader enables the CEM100’s components to dissipate heat
efficiently. All heat generating components are thermally conducted to the heat spreader in
order to avoid hot spots. Follow steps below to install heat spreader.
1.
There is a protective plastic covering on the thermal pads. This must be removed before
the heat spreader can be mounted.
2.
Each heat spreader is designed for a specific CEM module. The thermal pads on the
heat spreader are designed to make contact with the necessary components on the CEM
module. When mounting the heat spreader you must make sure that the thermal pads on
the heat spreader make complete contact (no space between thermal pad and
component) with the corresponding components on the CEM module. This is especially
critical for CEM modules that have higher CPU speeds (for example 1.0GHz or more) to
ensure that the heat spreader acts as a proper thermal interface for cooling solutions.
3.
This CPU module has seven assembly holes for installing heat spreader plate. Align and
use screws (M2.5x16Lx5pcs and M2.5x4Lx2pcs) to secure the heat spreader plate to the
CEM100. Be careful not to over-tighten the screws.

Switch Setting (SW1)
If SW1-1 is enabled for AC power input, the system will be automatically power on without
pressing soft power button. If SW1-1 is disabled for AC power input, it is necessary to manually
press soft power button to turn on the system. This function is similar to the feature of power
on after power failure, which is controlled by hardware circuitry instead of BIOS.
Properly configure switch setting on the CEM100 to meet your application purpose. See table
below for detailed information.

AMI BIOS Setup Utility
The AMI BIOS provides users with a built-in setup program to modify basic system
configuration. All configured parameters are stored in a battery-backed CMOS to save the
setup information whenever the power is turned off. This chapter provides users with detailed
description about how to set up basic system configuration through the AMI BIOS setup utility.
4.1
Starting
To enter the setup screens, follow the steps below:
1.
2.
Turn on the computer and press the <Del> key immediately.
After you press the <Del> key, the main BIOS setup menu displays. You can access the
other setup screens from the main BIOS setup menu, such as the Advanced and Chipset
menus.
It is strongly recommended that you should avoid changing the chipset’s defaults. Both AMI
and your system manufacturer have carefully set up these defaults that provide the best
performance and reliability.
4.2
Navigation Keys
The BIOS setup/utility uses a key-based navigation system called hot keys. Most of the BIOS
setup utility hot keys can be used at any time during the setup navigation process. These keys
include <F1>, <F2>, <Enter>, <ESC>, <Arrow> keys, and so on.
Note: Some of the navigation keys differ from one screen to another.

Watchdog Timer and GPIO
About Watchdog Timer
Software stability is major issue in most application. Some embedded systems are not
watched by human for 24 hours. It is usually too slow to wait for someone to reboot when
computer hangs. The systems need to be able to reset automatically when things go wrong.
The watchdog timer gives us solution.
The watchdog timer is a counter that triggers a system reset when it counts down to zero from
a preset value. The software starts counter with an initial value and must reset it periodically. If
the counter ever reaches zero which means the software has crashed, the system will reboot.
About GPIO
The onboard GPIO (general input and output) has 8 bits (GPI0~3 and GPO0~3). In default, all
pins are pulled high with +3.3V level (according to main power). The BIOS default settings are
4 inputs and 4 outputs where all of these pins are set to 1. Use these GPIO signals to control
cash drawers and sense warning signals from an Uninterrupted Power System (UPS), or
perform store security control.
