PrPMC8005E-1261 Motorola Processor PMC Module

The Emerson / Motorola PrPMC8005E Series Processor PMC Modules are a single-width, standard-length and standard-height Processor PCI Mezzanine Card (PrPMC) board. It is compatible with the PowerPlus III architecture and consists of an MPC7410 processor and the Harrier PCI-Host bridge/system memory controller ASIC. The PrPMC800 features 2MB of L2 cache, 32MB of flash memory (a second bank of flash can be located on the baseboard and accessed through the PMC P14 connector), one bank of SDRAM (128MB to 256MB) onboard, a 10BaseT/100BaseTX Ethernet channel based on the Intel 82559ER/82551IT device and an RS-232 transceiver providing debug capabilities through one of the Harrier UART channels.

Four 64-pin PMC connectors on the PrPMC800 are used to connect the PrPMC800 to the host board. One right-angle 20-pin connector located on the primary side of the PrPMC800 provides an interface to the asynchronous serial port and the processor JTAG/COP port, along with the RESET# and ABORT# signals 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 host board access.

Connectivity to the Ethernet channel is provided either by a front panel connector or by rear I/O via the P14 connector. The build option determines the connection method. Models of this board configured for Ethernet routing via the Pn4 do not have a front bezel. The PrPMC800 module can operate as a monarch (master) for the baseboard, or as a slave processor PMC, depending on the state of the MONARCH# signal from the PMC P12 connector. When configured as the monarch, the PrPMC800 enumerates the PCI bus, and monitors and services the four PCI interrupts. If configured to operate in the non-monarch mode, the PrPMC800 module does not enumerate the bus or service interrupts, but it may generate a PCI interrupt.
