XPort1002

The XPort1002 is a high-performance communications controller targeting low-cost applications. The XPort1002 combines an array of supported serial protocols and a flexible I/O routing structure to pack maximum versatility into an industry standard PMC module.

Powered by the MPC8270 (PowerQUICC II), the XPort1002 implements four serial communication ports providing a seven wire signal set (TXD, RXD, RTS, CTS, DCD, TXC, RXC) supporting either RS-232 or RS-422/RS-485 on a per-port basis. The XPort1002 supports HDLC/SDLC, UART, transparent, and BiSync modes, along with NRZ, NRZI, FM0, FM1, Manchester and Differential Manchester encoding. Coupled with support for two RS-232 serial management ports, the XPort1002 provides a wide range of serial options.

For the system designer, the XPort1002 will help drive both cost and power consumption out the system. Because the PCI bridge is integrated on chip, the XPort1002 draws up to 40% less power, and costs up to 30% less than conventional designs based on other processors. The XPort1002 is available in both standard air-cooled (0 to +55°C) and rugged air-cooled (-40 to +70°C) versions.
