XR16V2750
HIGH PERFORMANCE DUART WITH 64-BYTE FIFO
SEPTEMBER 2007
REV. 1.0.3
GENERAL DESCRIPTION
The XR16V27501 (V2750) is a high performance dual
universal asynchronous receiver and transmitter
(UART) with 64 byte TX and RX FIFOs. The device
operates from 2.25 to 3.6 volts with 5 Volt tolerant
inputs
and
is
pin-to-pin
compatible
to
Exar’s
ST16C2550 and XR16L2750. The V2750 register set
is identical to the XR16L2750 and is compatible to the
ST16C2550 and the XR16C2850 enhanced features.
It
supports
the
Exar’s
enhanced
features
of
programmable FIFO trigger level and FIFO level
counters,
automatic
hardware
(RTS/CTS)
and
software flow control, automatic RS-485 half duplex
direction control output and a complete modem
interface. Onboard registers provide the user with
operational status and data error flags. An internal
loopback
capability
allows
system
diagnostics.
Independent programmable baud rate generators are
provided in each channel to select data rates up to 8
Mbps at 3.3 Volt and 8X sampling clock. The V2750
is available in 48-pin TQFP and 32-pin QFN
packages.
NOTE: 1 Covered by U.S. Patent #5,649,122
