FEATURES - Efficient 32-bit, 331/3 MHz multi-function, target-only PCI controller, pliant to PCI Local Bus Specification 3.0 & PCI Power Management Specification 1.1 Eight UARTs fully software patible with 16C550type devices patible with existing 16C550/450 device drivers PCI 2.1, 2.2, 2.3 & 3.0 pliant Supports both 5.0-V & 3.3-V PCI signalling 32-byte deep FIFO per transmitter & receiver Baud rates up to 4.125 Mega-baud (using a 16.5 MHz input clock). Clock can be provided from crystal oscillator or external clock source Automated out-of-band flow control using CTS#/RTS# Configuration data is held in a small, low-cost serial Microwire TM patible EEPROM - - - - Driver-facilitated DSR/DTR & Xon/Xoff handshaking 5-,6-,7- & 8-bit data framing 1, 1.5 or 2 stop bits UART enhancements: - Clock prescaler allows more baud rate options - Readable FIFO levels & tuneable trigger levels improve device driver performance - Programmable “synchronization factor” allows baud rates up to fclock/4 - Extensions to standard register set are implemented in a safe, easy-to-use way Low-power design with separate power management control Operating temp. range : 0o C- 70o C 160-pin QFP package Operation via IO or memory mapping Support for multiple wake-up events - - - - - - - - - - - - - - DESCRIPTION The OX16PCI958 contains eight UARTs (Universal Asynchronous Receiver-Transmitters) and a host interface suitable for direct connection to a PCI bus. Once installed and configured by the host OS, it provides an eight-byte programming interface to each UART. The UARTs are fully software-patible with 16C550 devices. The device can be configured to fit the requirements of RS232 or RS422 applications. The UARTs convert between RS232-format serial data on separate transmit and receive lines, and byte-wide I/O writes and reads on the host interface. Malformed ining serial data is flagged along with the data in the receive FIFO. The state of the UART can be found at any time by reading status...
