4 Reference Manual XTX 820

Chapter 2 Product Overview

This introduction presents general information about the XTX Architecture and the XTX 820 ComputerOn-Module (COM). After reading this chapter you should understand:

• XTX Computer-On-Module concept

• XTX 820 architecture and features

• Major components

• Connectors

• Specifications

ETX® Concept and XTX™ Extension

The Embedded Technology eXtended (ETX) module concept is an off the shelf, multi vendor, singleboard-computer that integrates all the core components of a common PC and is mounted onto an application specific baseboard. ETX modules have a standardized form factor of just 95 mm x 114 mm and use an identical pin compatible connector on the four system connectors. The ETX module provides most of the PC functional requirements for any application. These functions include, but are not limited to, graphics, sound, keyboard/mouse, IDE, Ethernet, parallel, serial and USB ports. Four ruggedized connectors provide the baseboard interface and carry all the I/O signals to and from the ETX module.

Baseboard designers can utilize as little or as many of the I/O interfaces as deemed necessary. The baseboard can therefore provide all the interface connectors required to attach the system to the application specific peripherals. This versatility allows the designer to create a dense and optimized package, which results in a more reliable product while simplifying system integration. Most importantly ETX applications are scalable, which means once a product has been created there is the ability to diversify the product range through the use of different performance class ETX modules. Simply unplug one module and replace it with another, no redesign is necessary.

XTX™ is an expansion and continuation of the well-established and highly successful ETX standard. XTX offers the newest I/O technologies on this proven form factor. Currently, the ISA bus is found less often in modern embedded applications that offer a greater array of features. Consequently, the X2 connector for XTX replaces ISA with features that are currently not found on the ETX platform. These features include new serial high speed buses such as PCI Express™, ExpressCard, AC'97 HD audio, and Serial ATA®. XTX also provides the AC'97 High Definition Audio (HDA) and two additional USB 2.0 ports, bringing the USB total to six USB ports. The USB 2.0 and PCI Express interfaces can also support the next generation PCMCIA card in the ExpressCard. All the other signals found on the X1, X3, and X4 connectors remain the same in accordance with the ETX standard (Rev. 2.7) and therefore will be completely compatible. If the embedded application still requires the ISA bus, then a PCI-ISA bridge can be implemented on the application specific baseboard. If this solution is too co stly then the readily available XTX LPC bus located the Ampro XTX module can be used.

ETX or XTX modules work like a high-integration chip, plugging into your custom circuit board design to provide specific control for your logic application. See Figure 2-1.

Notes: *The In-rush current represents video, 256 MB RAM, and power only connected through the Ampro baseboard. Typically, in-rush current reflects the short duration current spike associated with charging large on-board bulk capacitance during pow er supply start up. However, the listed in-rush current value is the result of placing a switch on the DC output of a fully 'ramped' power supply to give a worst-case current value, which is much higher than the standard method. This in-rush value should be regarded as a maximum design guideline, not a requisite value.

**The Burn-In-Test (BIT) current setup has CRT video, 256 MB RAM, floppy drive (1), IDE hard disk drive (1), USB hard disk drive (1), USB CD-ROM (1), serial ports with loopbacks (3), keyboard, mouse, USB compact flash card reader with compact flash card (64 MB) installed (1), USB Jumpdrive (1), and the Ethernet port (1) operating under Microsoft® Windows®™ XP (SP2).

Thermal/Cooling Solutions

The Pentium/Celeron M processors used on the XTX 820 make use of the thermal monitor feature to help control the processor temperature. Refer to the Thermal Monitoring topic in Chapter 3, Hardware for more information. The maximum core operating temperature for Pentium M and Celeron M processors is 100°C. Both Pentium M and Celeron M processors and the Memory & Graphics Hub (Northbridge) require individual heatsi nks, but no fan. Ampro provides an optional heatspreader pl at e.

CAUTION To prevent processor overheating, you must provide an additional form of

cooling when using the heatspreader provided. The heatspreader plate is not a complete thermal solution for any of the processors listed.

XTX 820 Reference Manual 15

Chapter 3 Hardware

CPU (U1)

The XTX 820 offers three Intel processor choices; high performance 1.0 GHz Ultra Low Voltage (ULV) Celeron M CPU, 1.4 GHz Low Voltage (LV) Pentium M CPU, or 1.8 GHz Pentium M CPU.

Celeron M Processor

The Celeron M processor (Dothan core) at 1.0 GHz has 512 kB L2 Cache with a 400 MHz FSB (front side bus). The 1.0 GHz Celeron M 373 processor use 90 nm architecture and requires a heatsink, but no fan.

Pentium M Processors

The Pentium M 738 processor (Dothan core) at 1.4 GHz has 2 MB L2 Cache with a 400 MHz FSB (front side bus). The 1.4 GHz Pentium M 738 processor uses 90 nm architecture and requires a heatsink, but no fan.

The Pentium M 745 processor (Dothan core) at 1.8 GHz has 2 MB L2 Cache with a 400 MHz FSB (front side bus). The 1.8 GHz Pentium M 745 processor uses 90 nm architecture and requires a heatsink, but no fan below 60°C.

CAUTION If you choose to use a heat-spreader plate instead of an individual

heatsink for the processor, then you must provide an additional form of cooling. The heat-spreader plate is not a complete thermal solution for any of the processors listed.

Memory

The XTX 820 memory consists of the following elements:

• DDR2 SODIMM socket

• Flash memory

DDR2 SODIMM Socket (J5)

The XTX 820 supports a single 200-pin DDR2 SODIMM socket.

• SODI MM socket (J5) can support up to 1 GB of DDR2 memory

• Suppo rts PC2 3200 DDR 400 operating at 400 Mbps (200 MHz, 5 ns) or faster

• Supports +1.8V SDRAM

NOTE Ampro recommends using PC2 3200 DDR2 400 (400 Mbps, 200 MHz),

+1.8V, 5 ns, 200-pin, SDRAM SODIMM, or fast er. PC2 3 20 0 pr o vides the best performance for these Intel processors.

Flash Memory (U17)

There is an 8-bit wide, 512 kB flash device used for system BIOS and is connected to the I/O Hub (Southbridge), through an LPC bus transceiver. The flash memory is used to store system parameters for battery-free boot capability when there is no battery present. The BIOS is re-programmable and the features supported are detailed in Chapter 4, BIOS Setup Utility.

Interrupt Channel Assignments (IRQs)

The channel interrupt assignments are listed in Table 3-1.

Notes: In PIC mode, the PCI bus interrupt lines can be routed to any free IRQ.

1. Default, but can be changed to another interrupt. If disabled in BIOS Setup, the interrupt can be used for another purpose.

2. Function described is available if the baseboard is equipped with the Super I/O controller Winbond (W83627HG). This I/O controller is supported by the XTX 820 Embedded BIOS.

3. If the ATA/IDE configuration is set to enhanced mode in BIOS setup (serial ATA and parallel ATA native mode operation), IRQ14 and 15 are free for PCI/LPC bus.

4. In ACPI mode, IRQ9 is used for the SCI (System Control Interrupt). The SCI can be shared with a PCI interrupt line.
