ST16C1450/51
2.97V TO 5.5V UART
OCTOBER 2003
GENERAL DESCRIPTION
REV. 4.2.0
The ST16C1450, ST16C1451 series (here on
denoted as the 145X) is a universal asynchronous
receiver and transmitter (UART). The 145X is foot
print compatible to the SSI 73M1550 and SSI
73M2550 UART with one byte FIFO and higher
operating speed and lower access time. The 145X
provides enhanced UART functions with a modem
control interface, independent programmable baud
rate generators with clock rates to 1.5 Mbps. Onboard
status registers provide the user with error indications
and operational status. System interrupts and modem
control features may be tailored by external software
to meet specific user requirements. An internal loop-
back capability allows onboard diagnostics. The 145X
is available in a 28-pin PLCC/plastic-DIP 48-pin
TQFP packages. The Baud rate generator can be
configured for either crystal or external clock input
with the exception of the 28 pin 1451 package. An
external clock must be provided for the 28 pin 1451
package. Each package type, with the exception of
the 28 pin 1450, provides a buffered reset output that
can be controlled through user software. The 145X is
fabricated in an advanced CMOS process to achieve
low drain power and high speed requirements. The
ST16C145X is not compatible with the industry
standard 16450 and will not work with the standard
serial port driver in MS Windows (see pages 15-16 for
details). For a MS Windows compatible UART, see
the ST16C450.
