Introduction

This chapter provides a brief description of the PrPMC750 Processor PMC
Module and instructions for preparing and installing the hardware
including the optional SDRAM memory mezzanine module.
In this manual, the name PrPMC750 refers to all models of the PrPMC750
series boards unless otherwise specified. These are add-on modules
intended for use with any host carrier board that will accept a PMC or
processor PMC module.

PrPMC750 Description

The PrPMC750 is a Processor PCI Mezzanine Card (processor PMC)
board (refer to the VITA-32-199x Processor PMC Standard for Processor
PCI Mezzanine cards for more information). It is based on the PowerPC
MPC750 processor and the Hawk PCI-Host bridge/system memory
controller. The PrPMC750 features 1MB of L2 Cache, one bank of
SDRAM (32MB to 128MB) onboard with memory expansion capability,
and 8MB of FLASH.
Four 64-pin PMC connectors on the PrPMC750 are used to connect the
PrPMC750 to the host board. One right angle 20-pin connector, located on
the primary side of the PrPMC750, provides an interface to the async serial
port. The processor JTAG/COP port, along with the RESET# and
ABORT# signals, are used for debug support. The Serial port and
JTAG/COP interfaces, along with the ABORT_L signal, are also routed to
the PMC P14 connector for carrier board access.
The PrPMC750 may be purchased with an optional 140-pin AMP
connector installed on the bottom side of the board to provide a receptacle
for the memory expansion capability. The presence of this connector
increases the side two component height measurement and places it
outside the standard height.
