Specifications

This appendix provides general specifications, including mechanical,
electrical, and temperature for the PrPMC750 and the memory mezzanine.

Mechanical Characteristics

The mechanical outline of the PrPMC750 module will conform to the
dimensions defined by a single wide, standard length PMC module (74mm
x 149mm x 10mm stacking height). The side 2 component height of the
PrPMC750, without the optional memory mezzanine connector or
memory mezzanine, will conform to the standard side 2 height dimension
(3.5mm). The PrPMC750 with the memory mezzanine will fit within the
tall PMC envelope (20 mm). See

Electrical Characteristics

The voltage requirements and estimated power consumption for the
PrPMC750 are shown in the following table. The total power dissipation
for the PrPMC750 configured with a 350 MHz processor is 8.6 watts
typical, 12.5 watts max.

Airflow Requirements

The PrPMC750 module requires a minimum air flow of 450 LFM when
operating at 55 degrees C ambient temperature.
