General description
The SC16C550 is a Universal Asynchronous Receiver and Transmitter (UART) used
for serial data communications. Its principal function is to convert parallel data into
serial data, and vice versa. The UART can handle serial data rates up to 3 Mbits/s.
The SC16C550 is pin compatible with the ST16C550, TL16C550 and PC16C550,
and it will power-up to be functionally equivalent to the 16C450. Programming of
control registers enables the added features of the SC16C550. Some of these added
features are the 16-byte receive and transmit FIFOs, automatic hardware or software
ow control and Infrared encoding/decoding. The selectable auto-ow control feature
signicantly reduces software overload and increases system efciency while in FIFO
mode by automatically controlling serial data ow using RTS output and CTS input
signals. The SC16C550 also provides DMA mode data transfers through FIFO trigger
levels and the TXRDY and RXRDY signals. On-board status registers provide the
user with error indications, operational status, and modem interface control. System
interrupts may be tailored to meet user requirements. An internal loop-back capability
allows on-board diagnostics.
The SC16C550 operates at 5 V, 3.3 V and 2.5 V, and the Industrial temperature
range, and is available in plastic DIP40, PLCC44 and LQFP48 packages.
