Description
Application Notes
The ST16C550 is a universal asynchronous receiver and transmitter with
16 byte transmit and receive FIFO. A programmable baud rate generator
is pro- vided to 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 MODEM 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 0.6m CMOS process to
achieve low drain power and high speed requirements.
