Technical Specifications

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.
