OXCB950
Overview
The OXCB950 is a single chip UART solution for either cardbus or PCI-based serial add-in cards. It is a single function device, offering memory or IO mapped access to the ultra-high performance 950-type UART.

- Arbitrary trigger levels for receiver and transmitter FIFO interrupts and automatic in-band and out-ofband flow control Infra-red (IrDA) receiver and transmitter operation 9-bit data framing as well as 5,6,7 and 8 Global Interrupt Status and readable FIFO levels to facilitate implementation of efficient device drivers Detection of bad data in the receiver FIFO Operation via IO or memory mapping. 2 multi-purpose I/O pins which can be configured as interrupt input or ‘wake-up’ pins Auto-detection of optional MicrowireTM EEPROM, to reconfigure device 3.3V operation 100 pin TQFP package * * * * * *
- Single high-performance UART channel Cardbus/3.3v PCI compliant, single-function target controller. Fully compliant to PC Card Standards, and PCI Bus Specification 2.2, Power Management 1.0 Function access to preconfigure the UART prior to handover to generic device drivers UART fully software compatible 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 Automated out-of-band flow control using CTS#/RTS# and/or DSR#/DTR#
