FEATURES - - - - - - - - - - - - - Single full-duplex asynchronous channel 128-byte deep transmitter / receiver FIFO Fully software patible with industry standard 16C550 type UARTs Pin patible with TL16C550B/C, ST16C650 and TL16C750 IBM PC/AT patible Baud rates up to 15 Mbps in normal mode and 60Mbps in external 1x clock mode Readable FIFO levels Flexible clock prescaler from 1 to 31.875 Isochronous mode using external 1x baud rate clock up to 60Mbps 9-bit data framing as well as 5,6,7 and 8 Detection of bad data in the receiver FIFO Automated in-band flow control using programmable Xon/Xoff characters Transmitter and receiver can be disabled - Automated out-of-band flow control using CTS# / RTS# and DSR# / DTR# - Readable in-band and out-of-band flow control status - Programmable special character detection - Arbitrary trigger levels for receiver and transmitter FIFO interrupts and automatic in-band and out-of-band flow control - Transmitter idle interrupt (shift register and FIFO both empty) - Optional Infra-red (Ir DA) receiver and transmitter operation - RS-485 buffer enable signals - Software channel reset - Four byte device ID - Sleep mode (low operating current) - System clock up to 60 MHz (at 5V), 50 MHz at 3.3V - 44 PLCC and 48 TQFP packages - 5 volts operation (PLCC), 3.3/ 5V operation TQFP REV B ENHANCEMENTS The OX16C950B is an enhanced, fully backward-patible revision of the OX16C950 rev A. The chief enhancements are as follows - - All known errata fixed - Enhanced features first offered in OX16PCI954 added - these include controls for sleep-mode sensitivity, ability to read FCR and Good Data Status - 3V operation possible with 48 pin TQFP - Enhanced isochronous clocking options (optional inversions) - Enhanced system clock selection options (use of CLKSEL as a clock input) - Readable Tx Rdy, Rx Rdy status and forcing Tx Rdy or Rx Rdy inactive Hereafter OX16C950 rev B is simply referred to as OX16C950.
