OX16C954-PCC60-B / OX16C954_TQC60_B FEATURES • Four independent full-duplex asynchronous 16C950 high performance UART channels • 128-byte deep FIFO per transmitter and receiver • UARTs fully software compatible with industry standard 16C55x type UARTs • Pin compatible with TL16C554 and ST16C654 • Baud rates up to 15 Mbps in normal mode and 60Mbps in external 1x clock (isochronous) mode • Readable FIFO levels • Flexible clock prescaler from 1 to 31.875 • Automated in-band flow control using programmable Xon/Xoff characters, in both directions • 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-of- band flow control • Readable in-band and out-of-band flow control status • Programmable special character detection • Infra-red (IrDA) receiver and transmitter option • 5, 6, 7, 8 and 9-bits data framing • Detection of bad data in the receiver FIFO • Independent channel reset by software • Transmitter and receiver can be disabled • Transmitter idle interrupt • RS-485 buffer enable signals • Four byte device ID • Sleep mode (low operating current) • System clock up to 60 MHz at 5V, 50 MHz at 3.3V • 5.0 volt or 3.3v operation* • 68pin PLCC and 80pin TQFP package options. *Only the 80pin TQFP package supports operation at 5v or 3.3v. REV B ENHANCEMENTS The OX16C954B is an enhanced, backward-compatible revision of the OX16C954 rev A. It uses the newer core as in the OX16C950 rev B. The chief enhancements are as follows – • All known errata fixed • Full TCR range from 4-16 • Enhanced controls for sleep-mode sensitivity, ability to read FCR and Good Data Status • 3.3V operation with 80 pin TQFP • Enhanced isochronous clocking options (optional inversions, DTR/DSR) Hereafter OX16C954 rev B is simply referred to as OX16C954. OX16C954 rev B High Performance Quad UART with 128-byte FIFOs Intel / Motorola Bus Interface |
