ST16C2450
2.97V TO 5.5V DUART
MAY 2005
REV. 4.0.1
GENERAL DESCRIPTION
The ST16C2450 (2450) is a dual universal asynchro-
nous
receiver
and
transmitter
(UART).
The
ST16C2450
is
an
improved
version
of
the
ST16C2450 with lower operating voltage and 5 volt
tolerant inputs. The 2450 provides enhanced UART
functions, a modem control interface and data rates
up to 1.5 Mbps. Onboard status registers provide the
user with error indications and operational status. In-
dependent programmable baud rate generators are
provided to select transmit and receive clock rates up
to 1.5 Mbps. An internal loopback capability allows
onboard diagnostics. The 2450 is available in a 44-
pin PLCC and 48-pin TQFP packages. The 2450 is
fabricated in an advanced CMOS process capable of
operating from 2.97 volt to 5.5 volt power supply. The
devices with a top marking of "A2 YYWW" or newer
have 5 volt tolerant inputs.
APPLICATIONS
• Portable Appliances
• Telecommunication Network Routers
• Ethernet Network Routers
• Cellular Data Devices
• Factory Automation and Process Controls
