The XPort1020 is a communications controller targeting high-performance yet low-cost applications. The XPort1020 combines a wide array of supported serial protocols, a broad range of serial interface standards, and a flexible I/O routing structure to pack maximum flexibility into an industry-standard cPCI form factor.
Powered by up to three Freescale MPC8270 (PowerQUICC II) processors, the XPort1020 implements twelve serial communication ports, each providing a EIA-530-A-compliant signal set. Support for HDLC/SDLC, UART, transparent, and BiSync modes, with NRZ, NRZI, FM0, FM1, Manchester, and Differential Manchester encoding is also provided. Coupled with software-configurable support for RS-232, RS-422, RS-423, RS-485, and MIL-STD-188-114, the XPort1020 provides a wide range of serial options.
For a system designer, the XPort1020 will help drive both cost and power consumption down. Because the PCI bridge is integrated on-chip and the processors are linked via the 60x bus, the XPort1020 draws less power and costs less than conventional designs based on other processors that require a PCI bridge.
