FEATURES - - - - - - - - - Two 16C950 High performance UART channels IEEE1284 pliant SPP/EPP/ECP parallel port Multi- function target PCI controller. Fully pliant to PCI bus specification 2.2 and PCI Power Management 1.0. Function access to pre-configure each UART and the parallel port, prior to handover to generic device drivers. UARTs fully software patible with 16C550- type devices. Baud rates up to 15Mbps in asynchronous mode and 60Mbps in external 1x clock 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 - - - - - - - - - - - OX16PCI952 DATA SHEET DS_B008A_00 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- ofband flow control Infra-red (Ir DA) receiver and transmitter operation 5, 6, 7, 8 and 9-bits data framing Global Interrupt Status and readable FIFO levels to facilitate implementation of efficient device drivers Detection of bad data in the receiver FIFO 2 multi-purpose IO pins which can be configured as interrupt inputs or ‘wake-up’ pins (via local registers). Auto-detection of a range of optional Microwire TM patible EEPROMs, to reconfigure device. Operation via IO or memory mapping. 5.0V operation 128 pin TQFP package DESCRIPTION The OX16PCI952 is a single chip solution for PCI-based serial and parallel expansion add-in cards. It is a dual function device, offering IO or memory mapped access to the two ultra-high performance OX16C950 UARTs and the bi-directional parallel port. These functions are defined by Function 0 and Function 1, respectively. Serial port cards with 2 serial ports and a parallel port can be designed without redefining any device parameters. Each UART channel in the OX16PCI952, is the fastest available PC-patible UART, offering data rates up to 15Mbps and 128-byte deep transmitter and...
