General Description

The PrPMC800/800ET is a Motorola processor PMC module compatible with the PowerPlus III architecture. It consists of an MPC750-class, MPC7410, or MPC7410 (N) processor and:

L2 backside cache

Harrier System Memory Controller/PCI Host Bridge ASIC

32MB of flash memory

64MB to 512MB of ECC-protected SDRAM on board with memory expansion capability

10BaseT/100BaseTX Ethernet controller

Debug serial port

The PrPMC800/800ET module interfaces to the host board PCI bus via the PMC P11, P12 and P13 connectors. These provide a 64-bit PCI interface (that is, 33 MHz/66 MHz capable) between the host board and the PrPMC800/800ET. The PrPMC module draws +3.3V through the PMC connectors. The onboard Processor Core Power Supply derives the core voltage from the +3.3V power. The clock generator derives all of the required onboard clocks from the PCI clock input on P11.

The PrPMC800/800ET module has a 2mm header onboard to support module debug operations. This header provides the interface to the debug serial RS-232 port and an interface to the processor JTAG/COP port.
