DESCRIPTION
The OX16C954 is a single chip solution for 4 channel serial
add-in cards.
Each UART channel in the OX16C954 offers data rates up
to 15Mbps and 128-byte deep transmitter and receiver
FIFOs. Deep FIFOs reduce CPU overhead and allow
utilisation of higher data rates.
Each UART channel is software compatible with the widely
used industry-standard 16C550 devices and compatibles,
as well as the OX16C95x family of high performance
UARTs. It is pin-compatible with the TL16C554, ST16C654
devices.
In addition to increased performance and FIFO size, the
UARTs also provide the full set of OX16C95x enhanced
features. These include improved flow controls such as
automated software flow control using Xon/Xoff and
automated hardware flow control using CTS#/RTS# and
DSR#/DTR# to 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 conditions allowing drivers to restart
gracefully. The OX16C954 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 OX16C954 is ideally suited to PC applications, such
as high-speed multi-port add-in cards that 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, OX16C954 also has a low
operating current and sleep mode for battery powered
applications.
