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.
