XPort1018

The XPort1018 is a communications controller targeting high-performance yet low-cost applications. The XPort1018 combines a wide array of supported serial protocols, an RS-232 serial interface, and a flexible I/O routing structure, to pack maximum flexibility into an industry-standard PCI form factor.

Powered by two Freescale MPC8270 (PowerQUICC II™) processors, the XPort1018 implements eight serial communication ports, each providing an eight-wire signal set (TXD, RXD, RTS, CTS, DCD, DTR, TXC, RXC). Coupled with support for HDLC/SDLC, UART, transparent, and BiSync modes, with NRZ, NRZI, FM0, FM1, Manchester and Differential Manchester encoding, the XPort1018 provides a wide range of serial options.

For the system designer, the XPort1018 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 XPort1018 draws less power and costs less than conventional designs based on other processors that require a PCI bridge.
