ST16C450
Rev. 4.20
PLCC Package
UNIVERSAL ASYNCHRONOUS
RECEIVER/TRANSMITTER (UART)
GENERAL DESCRIPTION
The ST16C450 is a universal asynchronous receiver
and transmitter. The ST16C450 is an improved ver-
sion of the NS16450 UART with higher operating
speed and lower access time. A programmable baud
rate generator is provided to select transmit and
receive clock rates from 50 Bps to 1.5 Mbps.
The ST16C450 on board status registers provides the
error
conditions, type and status of the transfer
operation being performed. Included is complete
MODEM control capability, and a processor interrupt
system that may be software tailored to the user’s
requirements. The ST16C450 provides internal loop-
back capability for on board diagnostic testing.
The ST16C450 is available in 40 pin PDIP, 44 pin
PLCC, and 48 pin TQFP packages. It is fabricated in
an advanced CMOS process to achieve low drain
power and high speed requirements.
FEATURES

1.5 Mbps transmit/receive operation (24MHz)
Programmable word lengths (5, 6, 7, 8)
Even, odd, force, or no parity generation and
detection
Independent transmit and receive control
Standard modem interface
Low operating current ( 1.2mA typ.)
