2.5Subsystem Descriptions

Subsystem features refer to the socket and connector locations on the Crown Beach Board. Socket and connector locations are labeled with a letter-number combination. Refer to the silkscreen labeling on Crown Beach Board for location detail.

2.5.1Intel® SCH Chipset

Processor interface at 400/533 MHz

Single channel DDR2 memory interface running at 400/533 MT/s

Two PCI Express* ports, x1

Eight USB 2.0 compatible ports

One ATAPI-6 (UDMA 100MB/s) IDE channel

Intel® HD Audio

Three SDIO/MMC interfaces

One channel 24-bit LVDS

One channel SDVO

LPC bus

2.5.2System Memory

Supports a single DDR2 SO-DIMM socket. SO-DIMMs must be un-buffered and compliant with Raw Cards A or C as defined by JEDEC.

Supports 400- or 533-MHz memory bus frequencies.

Note: SO-DIMM support is only provided for validation purposes. The Intel® Centrino®

Atom™ Processor Technology Platform Design Guide provides component implementations for memory down solutions. The DDR2 SODIMM Architecture’s Implementation for Intel® System Controller Hub (SCH) US15W whitepaper provides guidelines for implementing a SO-DIMM solution, although the recommendations are based on simulation only and have not been validated. It is recommended that customers validate their designs.

2.5.3Display

The reference board has two options for displaying video:

LVDS – location is J5G2

SDVO – location is J7C2

Note: The customer reference board supports single channel LVDS only. Table 4 is a listing of displays that have been tested with Crown Beach.
