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.

DESCRIPTION
The OX16C950 is a single-channel ultra-high performance
UART offering data rates up to 15Mbps and 128-deep
transmitter and receiver FIFOs. Deep FIFOs reduce CPU
overhead and allow utilisation of higher data rates.
It is software compatible with the widely used industry-
standard 16C550 type devices and compatibles, as well as
other OX16C95x family devices. It is pin-compatible with
the TL16C550, ST16C650 devices.
In addition to increased performance and FIFO size, the
OX16C950 also provides enhanced features including
improved flow control. Automated software flow control
using Xon/Xoff and automated hardware flow control using
CTS#/RTS# and DSR#/DTR# prevent FIFO over-run. Flow
control and interrupt thresholds are fully programmable and
readable, enabling programmers to fine-tune the
performance of their system. FIFO levels are readable to
facilitate fast driver applications.
The addition of software reset enables recovery from
unforeseen error condition allowing drivers to restart
gracefully. The OX16C950 supports 9-bit data frames
used in multi-drop industrial protocols. It also offers multiple
external clock options for isochronous applications, e.g.
ISDN, xDSL.
The OX16C950 is ideally suited to PC applications, such
as high-speed COM port add-in cards which enable PC
users to take advantage of the maximum performance of
analogue modems or ISDN terminal adapters. It is also
suitable for any equipment requiring high speed
RS232/RS422/RS485 interfaces. Fabricated in 0.6µm
process, OX16C950 also has a low operating current and
sleep mode for battery powered applications.
