The CSBC-6872 is a sophisticated and flexible telecom product from the ACTIS Computer PowerQUICC II product line. This computer board is based on the MPC8270 from MOTOROLA (PowerQUICC II). This processor is rated up to 855 MIPS @ 450 MHz and includes a very efficient SDRAM controller. One of the key feature of this device is to include a Quad Integrated Communications Controller (QUICC). This QUICC is implemented on several products in the Motorola embedded processor family. It provides an dedicated module containing RISC CPU and DMA channels for handling very efficiently a wide range of communications protocols. The CSBC-6872 includes 16 MByte of 32-bit Flash. This Flash memory supports a dual bank configuration. This board is supplied with 128 MByte of SDRAM. To maximize the performance, this memory is directly connected to the processor 64-bit data bus. Three Fast Ethernet 100Base-TX/10Base-T are supplied with auto-negociation support. The CSBC-6872 supports four independant Serial Communication Controllers with multiprotocol support of RS-232 or RS-422/RS-485/V.35 standards. All ports can receive or transmit serial clock for synchronous operations.
