SC16C654 - Quad UART with 64-byte FIFO and infrared (IrDA) encoder/decoder

This page provides the datasheet information for the SC16C654, a member of the SC1 Quad UART with 64-byte FIFO and infrared (IrDA) encoder/decoder family.

Datasheet Summary

Description

The SC16C654/654D 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.

Features

  • of the SC16C654/654D. Some of these added features are the 64-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 SC16C654/654D also provides DMA mode data transfers through FIFO trigger levels and the TXRDY and RXRDY signals.

SC16C654/654D Quad UART with 64-byte FIFO and infrared (IrDA) encoder/decoder Rev. 04 — 19 June 2003 Product data 1. Description The SC16C654/654D 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 SC16C654/654D is pin compatible with the ST16C654 and TL16C754 and it will power-up to be functionally equivalent to the 16C454. Programming of control registers enables the added features of the SC16C654/654D.
