8751 - Conduction Cooled PMC Single Board Computer with 3 10/100TX Auto-sensing Ethernet Controllers The 8751 PMC is a highly integrated module with single board computer functionalities. This rugged PMC board is intended for embedded applications requiring conduction cooling. The board was designed in accordance with ANSI VITA 20 and IEEE1386.1 PCI mezzanine card standards. It features a high performance, 32-bit PowerPC processor with three Fast Ethernet controllers. It can be used in conjunction with CompactPCI, VME carriers or proprietary designs. Multiple networks or embedded can be addressed with this board: • Processing requirements with a high level of integration and low power consumption • Communication controller with Multiple Ethernet Links • Ethernet channels with redundancy Description The 8751 is powered by a MPC8250/70, part of the PowerQUICC II processor family. This embedded processor couples a 603e core with a RISC communication processor, and three Fast Ethernet controllers. The low 4W power design simplifies system integration. The board implements a 64-bit PowerPC local bus. This local bus is used by the host via the 32-bit PCI bus through a PowerPC-to-PCI bridge. The 8751 can be used in three different modes: Monarch, Non-Monarch or stand-alone and may be used as the host or node. Depending on the mode, it can act as the host processor. Three full-duplex 802.3 and Fast Ethernet controllers are provided in conjunction with three PHY 10/100TX interfaces. Each controller implements a local FIFO and DMA channel and supports the promiscuous mode. Thermal management is supplied by temperature sensors. Surge protection implemented on each Ethernet lines make this board particularly suited to harsh, industrial environments. This board is offered standard with conformal coating. Four multi-purpose serial controllers are provided (each with a data rate up to 10Mbits) on the Pn4 rear I/O or the reverse optional Pn3 connector. SPI and I²C bus are also available on these connectors. In addition Pn3 provides several GPIO. An engineering kit is available to enable easy utilization of debug tools: JTAG/COP/Async RS232 port and external reset. 8751 Features - Tools A firmware monitor allowing loading files from Processor Core Ethernet via Bootp, running files in RAM or • PPC603e with FPU 32 bit RISC architecture flash.
