POWER REQUIREMENTS - 100% stressed

Typical Values

* From backplane via PICMG® connector.
** From ATX12V power supply or equivalent via P24 connector.

The Intel® Pentium® 4 processor¡¯s power requirements created the need for an additional on-board 4-pin power connector (P24). This connector requires +12V from an external power supply that conforms to the ATX12V power specification.

This external power supply should have a minimum wattage rating of at least 250W. The T4G also requires that 3.3V be applied to the backplane from the power supply.

The system power supply must conform to the power sequencing specifications of ATX compliant power supplies. Voltage levels must be regulated within a range of +/- 5%.

POWER REQUIREMENTS - Idle

MEMORY SLOT POPULATION

Memory modules can be installed in one or both DIMM sockets. If only one DIMM module is used, it should be populated in the top DIMM socket (Bank 2 - Bk2). If two modules of different speeds are used, the 845GV chipset sets the memory interface speed to the speed of the slower DIMM module. Registered DIMMs are not supported. All memory modules must have gold contacts. Only non-stacked DIMMs are supported by the SBC¡¯s chipset and BIOS.

IOBxx EXPANSION BOARDS (OPTIONAL)
