It is specifically designed to meet the latest system requirements of high performance, lead (Pb) -free and reduced package sizes. The bridge can be used in a wide range of applications such as Remote Access Servers, Automation, Process Control, Instrumentation, POS, ATM and Multi-port RS232/RS422/RS485 Cards. The PI7C9X7958 provides one x1 PCIe® (dual simplex 2.5 Gbps) uplink port, and it is fully compliant with PCI express 1.1 and PCI® power management 1.2 specifications. The bridge supports eight high performance UARTs, each of which supports Baud rate up to 15 Mbps in asynchronous mode. The UARTs support in-band and out-band auto flow control, arbitrary trigger I/O mapping and memory mapping. The PI7C9X7958 is fully software compatible with 16C550-type device drivers and can be configured to fit the requirements of RS232, RS422 and RS485 applications. The EEPROM interface is provided for system implementation convenience. Some registers can be pre-programmed via hardware pin settings to facilitate system initialization. For programming flexibility, all of the default configuration registers can be overwritten by EEPROM data, such as sub-vendor and sub-system ID. Industry Specifications Compliance PCI Express Base Specification, Revision 1.1 PCI Express CEM Specification, Revision 1.1 PCI Power Management 1.2 Advanced Configuration Power Interface (ACPI) Specification PCI Standard Hot-Plug Controller (SHPC) and Subsystem Specification Revision 1.0. Features Support 8 high performance 16C950 UART in single chip Fully software compatible with 16C550-type device drivers 128-byte transmit and receive FIFO Flexible clock pre-scaler from 4 to 46 Automated in-band flow control using programmable Xon/ Xoff in both directions Automated out-of-band flow control using CTS#/ RTS# and/or DSR#/ DTR# Arbitrary trigger levels for receiver and transmitter FIFO interrupts and automatic in-band and out-band flow control Data framing sizes: 5, 6, 7, 8 and 9 Configurable using non-volatile configuration memory (EEPROM) Global Interrupt Status and readable FIFO levels to facilitate implementation of efficient device drivers. Operation via IO or memory mapping Detection of bad data in the receive FIFO Baud rate up to 15 Mbps in asynchronous mode Supports up to 256-byte maximum payload size 1.8 and 3.3V operation Power dissipation: 0.9 W typical in normal mode Industrial Temperature Range -40o to 85o Package: 12x12mm, 160-pin LFBGA, w/0.8mm ball pitch - Pb free and 100% Green.
