April 2005
GENERAL DESCRIPTION
The ST16C550 (550) is a universal asynchronous re-
ceiver and transmitter with 16 byte transmit and receive
FIFO. It operates at 2.97 to 5.5 volts. A programmable
baud rate generator can select transmit and receive
clock rates from 50 bps to 1.5 Mbps.
The ST16C550 is an improved version of the NS16C550
UART with higher operating speed and lower access
time. The ST16C550 on board status registers provides
the error conditions, type and status of the transfer
operation being performed. Included is complete MO-
DEM control capability, and a processor interrupt
system that may be software tailored to the user’s
requirements. The ST16C550 provides internal loop-
back capability for on board diagnostic testing.
The ST16C550 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.
