SC16C554/554D

Quad UART with 16-byte FIFO and infrared (IrDA)

encoder/decoder

Rev. 02 — 13 March 2003

Product data

1. Description

The SC16C554/554D is a 4-channel Universal Asynchronous Receiver and

Transmitter (QUART) 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 5 Mbits/s. It comes with an Intel or Motorola interface.

The SC16C554/554D is pin compatible with the ST16C554 and TL16C554 and it will

power-up to be functionally equivalent to the 16C454. Programming of control

registers enables the added features of the SC16C554/554D. 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 SC16C554/554D 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 SC16C554/554D operates at 5 V, 3.3 V and 2.5 V, and the industrial temperature

range, and is available in plastic PLCC68, LQFP64, and LQFP80 packages.

2. Features

■ 5 V, 3.3 V and 2.5 V operation

■ Industrial temperature range

■ Pin compatibility with the industry-standard ST16C454/554, ST68C454/554,

ST16C554, TL16C554

■ Up to 5 Mbits/s data rate at 5 V and 3.3 V, and 3 Mbits/s at 2.5 V

■ 16-byte transmit FIFO

■ 16-byte receive FIFO with error ﬂags

■ Automatic software/hardware ﬂow control

■ Programmable Xon/Xoff characters

■ Software selectable Baud Rate Generator

■ Four selectable Receive FIFO interrupt trigger levels

■ Standard modem interface or infrared IrDA encoder/decoder interface

■ Sleep mode

■ Standard asynchronous error and framing bits (Start, Stop, and Parity Overrun

Break)

■ Transmit, Receive, Line Status, and Data Set interrupts independently controlled
