XR16L2752
2.25V TO 5.5V DUART WITH 64-BYTE FIFO
AUGUST 2004
GENERAL DESCRIPTION
REV. 1.2.0
The XR16L2752
1
(2752) is a low voltage dual
universal asynchronous receiver and transmitter
(UART) with 5 Volt tolerant inputs. The device
operates from 2.25 to 5.5 Volt supply range and is
pin-to-pin compatible to Exar’s ST16C2552 and
XR16C2852. The 2752 register set is compatible to
the ST16C2552 and the XR16C2852 enhanced
features. It supports the Exar’s enhanced features of
64 bytes of TX and RX FIFOs, 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 6.25 Mbps at 5 Volt and 8X
sampling. The 2752 is available in the 44-pin PLCC
package.
