topGeneral 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 flow control and Infrared encoding/decoding. The selectable auto-flow control feature significantly
reduces software overload and increases system efficiency while in FIFO mode by automatically controlling
serial data flow 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.
