Processor; Supported Memory - ADLINK Technology cPCI-6810 User Manual

Processor

The cPCI-6810/6820 motherboard is based on the RCC/
ServerWorks Champion LE chipset and supports a single or dual
Intel Mobile Pentium III processor – M. The supported CPU
package is a micro-FCBGA.
The Intel® Pentium® III processor - Low Power is a 0.18-micron
product, which is a highly integrated assembly with all its
immediate system-level support. This mobile version of the
Pentium III processor runs at a lower voltage than the desktop
version.
The 256 KB on-die transfer L2 cache is integrated with the CPU,
eliminating the need for separate components and improving
performance. The Intel® Pentium® III processor - Low Power also
operates on a 100/133 MHz Front Side Bus for faster access to
memory and data. The FSB speed depends on the CPU type with
its core speed is automatically detected by the BIOS.

Supported Memory

The cPCI-6810/6820 supports PC100/PC133 registered SO-
DIMMs only. The SDRAM speed, type, and size can be
determined by the BIOS reading the DIMM presence detect bits
on the SMBus. The DRAM timing register, which provides the
DRAM speed control for the entire array, must be programmed to
use the parameters of the slowest installed SDRAM. The DRAM
interface supports 64Mbit, 128Mbit, and 256Mbit technology
allowing up to 512MB per double-sided SO-DIMM. The cPCI-
6810/6820 can support up to 2GB of SDRAM memory with four
144-pin SO-DIMMs. Refer to the table below for memory size
configurations according to model type.
