СРB904 is a highly integrated ETX form-factor computer-on-module with low overal power consumption and compact size of

114 × 95 mm.

Fastwel CPB904 gives customers benefits of access to the full universe of 32-bit x86 software and high design flexibility at

extremely low thermal budget.

The board can serve various embedded applications where low power dissipation and high time-to-market are the most important factors.

CPB904 is based on x86 code compatible low Power CPU AMD Geode™ LX800 and AMD Geode™ I/O companion chip (CS5536).

The AMD Geode™ LX800 processor operates at maximum power of 3.9 W (TDP) and 1.8 W typically at 500 MHz while highly

integrated I/O companion chip AMD CS5536 operates at 2.4 W typically at 500 MHz.

Integrated Floating Point Unit supports Intel® MMX and AMD 3DNow!™ Technology instruction sets.

Dynamic Memory interface supports 64-bit DDR SDRAM and soldered 256 MB memory bank.

CPB904 provides high resolution graphical interfaces (simultaneously) for CRT displays up to 1920×1440 and LCD panels

up to 1024×768.

Peripheral devices can be connected to СРB904 through 4 high-speed USB 2.0 ports, PS/2 port, 3 COM ports, LPT interface or

17 programmable discrete I/O lines.

Additional reliability of СРB904 is provided by reserved CMOS memory and a set of system monitoring features.

Power management system is compliant with Advanced Power Management v1.1 and ACPI (Normal, Sleep and SaveToRAM


The CPU module requires application specific baseboard with ETX standard defined connectors.

СРB904 operates in industrial temperature range (-40°С to +85°C)
