OXMPCI954 Datasheet | Oxford Semiconductor

FEATURES - Integrated High Performance Quad UARTs, 8-bit Local Bus/Parallel Port. 3.3v PCI/mini PCI interface. - - - - - - - - - - - - - - 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-of-band flow control Infra-red (Ir DA) receiver and transmitter operation 9-bit data framing, as well as 5,6,7 and 8 bits Detection of bad data in the receiver FIFO Global Interrupt Status and readable FIFO levels to facilitate implementation of efficient device drivers. Local registers to provide status/control of device functions. 12 multi-purpose I/O pins, which can be configured as input interrupt pins or ‘wake-up’. Auto-detection of a wide range of optional Microwire TM patible EEPROMs, to re-configure device parameters. Function access, to pre-configure each function prior to handover to generic device drivers. Operation via IO or memory mapping. 3.3V operation (5v tolerance on selected I/Os) Extended Operating Temp. Range : -40C to 105C 160-pin LQFP or 176-pin VBGA package - - - - - - - - - - - Software patible with OX16PCI954 Four 16C950 High performance UART channels 8-bit Pass-through Local Bus (PCI Bridge) IEEE1284 pliant SPP/EPP/ECP parallel port (with external transceiver) Efficient 32-bit, 33MHz, Multi-function target-only PCI controller, fully pliant to PCI Local Bus specification 3.0, and PCI Power Management Specification 1.1 PCI and mini PCI Modes (with CLKRUN# and D3cold support in mini PCI modes) UARTs fully software patible with 16C550-type devices. UART operation up to 60 MHz via external clock source. Up to 20MHz with the crystal oscillator. Baud rates up to 60Mbps in external 1x clock mode and 15Mbps in asynchronous mode. 128-byte deep FIFO per transmitter and receiver Flexible clock prescaler, from 1 to 31.875 Automated in-band flow control using programmable Xon/Xoff in both directions DESCRIPTION The OXm PCI954 is a single chip solution...
