Product: PCI Express Quad UART I/O Bridge Part Numbers: PI7C9X7954 Operation via IO or memory mapping Product Description Detection of bad data in the receive FIFO The PI7C9X7954 is a PCI Express Quad UART (Universal Baud rate up to 15 Mbps in asynchronous mode. Asynchronous Receiver-Transmitters) I/O Bridge. It is Supports up to 256-byte maximum payload size specifically designed to meet the latest system requirements 1.8 and 3.3V operation of high performance, lead (Pb) -free and reduced package Power dissipation: 0.8 W typical in normal mode sizes. The bridge can be used in a wide range of applications o o Industrial Temperature Range -40 to 85 such as Remote Access Servers, Automation, Process Package: 14x14mm, 128-pin LQFP, Pb free and 100% Control, Instrumentation, POS, ATM and Multi-port Green. RS232/RS422/RS485 Cards. The PI7C9X7954 provides one x1 PCIe (dual simplex 2.5 Gbps) uplink port, and it is fully compliant with PCI express 1.1 and PCI power Software support TM management 1.2 specifications. The bridge supports four Microsoft Windows 2000/2003/XP/Vista 32/64-bit TM high performance UARTs, each of which supports Baud rate Microsoft Windows CE 5.0/6.0 up to 15 Mbps in asynchronous mode. The UARTs support Linux 2.6 and above in-band and out-band auto flow control, arbitrary trigger I/O mapping and memory mapping. The PI7C9X7954 is fully Applications software compatible with 16C550-type device drivers and Remote Access Servers can be configured to fit the requirements of RS232, RS422 Network / Storage Management and RS485 applications. The EEPROM interface is provided Factory Automation and Process Control for system implementation convenience. Some registers can Instrumentation be pre-programmed via hardware pin settings to facilitate Multi-port RS-232/ RS-422/ RS-485 Cards system initialization. For programming flexibility, all of the Point-of-Sale Systems (PoS) default configuration registers can be overwritten by Industrial Control (IPC) EEPROM data, such as sub-vendor and sub-system ID.
