SC16C550

Universal Asynchronous Receiver/Transmitter (UART)

with 16-byte FIFO and infrared (IrDA) encoder/decoder

Rev. 05 — 19 June 2003

Product data

1. 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

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.

2. Features

■ 5 V, 3.3 V and 2.5 V operation

■ Industrial temperature range

■ After reset, all registers are identical to the typical 16C450 register set

■ Capable of running with all existing generic 16C450 software

■ Pin compatibility with the industry-standard ST16C450/550, TL16C450/550,

PC16C450/550

■ Up to 3 Mbits/s transmit/receive operation at 5 V, 2 Mbits/s at 3.3 V, and

1 Mbit/s at 2.5 V

■ 16 byte transmit FIFO

■ 16 byte receive FIFO with error ﬂags

■ Programmable auto-RTS and auto-CTS

◆ In auto-CTS mode, CTS controls transmitter

◆ In auto-RTS mode, RxFIFO contents and threshold control RTS

■ Automatic software/hardware ﬂow control

■ Programmable Xon/Xoff characters

■ Software selectable Baud Rate Generator

■ Four selectable Receive FIFO interrupt trigger levels
