XR16V2752
HIGH PERFORMANCE DUART WITH 64-BYTE FIFO
JULY 2007
REV. 1.0.2
GENERAL DESCRIPTION
The XR16V27521 (V2752) 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
ST16C2552,
XR16L2552
and
XR16L2752.
The
V2752 register set is identical to the XR16L2752 and
is compatible to the ST16C2552 and the XR16C2852
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 V2752 is available in 44-pin PLCC and 32-
pin QFN packages.
NOTE: 1 Covered by U.S. Patent #5,649,122
