OX16C954 rev B  
High Performance Quad UART with 128-byte FIFOs  
Intel / Motorola Bus Interface  
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  
·
·
·
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  
·
·
Pin compatible with TL16C554 and ST16C654  
·
·
·
·
·
·
·
·
·
Independent channel reset by software  
Transmitter and receiver can be disabled  
Transmitter idle interrupt  
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  
RS-485 buffer enable signals  
Four byte device ID  
·
Automated in-band flow control using programmable  
Xon/Xoff characters, in both directions  
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*  
·
·
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  
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.
