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.

SODIMM socket (J5) can support up to 1 GB of DDR2 memory

Supports 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 faster. PC2 3200 provides

 

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.
