XR16M2752
1.62V TO 3.63V HIGH PERFORMANCE DUART WITH 64-BYTE FIFO
AUGUST 2007
REV. 1.0.0
GENERAL DESCRIPTION
The XR16M27521 (M2752) is a high performance
dual universal asynchronous receiver and transmitter
(UART) with 64 byte TX and RX FIFOs. The device
operates from 1.62 to 3.63 volts and is pin-to-pin
compatible
to
Exar’s
ST16C2552,
XR16L2552,
XR16L2752 and XR16V2752. The M2752 register set
is identical to the XR16V2752 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 M2752
is available in 44-pin PLCC and 32-pin QFN
packages.
NOTE: 1 Covered by U.S. Patent #5,649,122
