CPU (U1)
The LittleBoard 800 offers high performance Intel processors at 1.4GHz Low Voltage (LV) Pentium®
M 738, 1.0GHz Ultra Low Voltage (ULV) Celeron® M 373, or 600MHz Ultra Low Voltage (ULV)
Celeron M processor.
Celeron M Processors
The 600MHz Celeron M processor (Banias core) has 512kB L2 Cache on board, with a 400MHz FSB
(front side bus). This Celeron M processor uses 130nm architecture and requires a heatsink, but no fan.
The 1.0GHz Celeron M processor (Dothan core) has 512kB L2 Cache on board with a 400MHz FSB.
This Celeron M 373 processor uses 90nm architecture and requires a heatsink, but no fan.
Pentium M Processor
The 1.4GHz Pentium M 738 processor (Dothan core) has 2MB L2 Cache on board with a 400MHz FSB.
This Pentium M 738 processor uses 90nm architecture and requires a heatsink, but no fan below 70° C..
Memory
The LittleBoard 800 memory consists of the following elements:
•
DDR DIMM RAM
•
Flash memory
DDR DIMM Memory (DIMM1)
The LittleBoard 800 supports a single standard 184-pin DDR DIMM slot.
• DIMM slot can support up to 1GB of memory
• Supports PC2100 (266MHz) or PC2700 (333MHz) DDR RAM
• +2.5V SDRAM
Flash Memory (U13)
There is an 8-bit wide, 512kB flash device used for system BIOS that is connected to the I/O Hub,
82801DBM (Southbridge), through the LPC bus. The BIOS is re-programmable and the supported
features are detailed in Chapter 4, BIOS Setup.
