OX16C950 rev B
High Performance UART
with 128 byte FIFOs
FEATURES
• Single full-duplex asynchronous channel
• 128-byte deep transmitter / receiver FIFO
• Fully software compatible with industry standard
16C550 type UARTs
• Pin compatible with TL16C550B/C, ST16C650 and
TL16C750
• IBM PC/AT compatible
• 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 (IrDA) 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-compatible 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 TxRdy, RxRdy status and forcing TxRdy or RxRdy inactive
Hereafter OX16C950 rev B is simply referred to as OX16C950.
