UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C554DIB64,151 is a quad Universal Asynchronous Receiver/Transmitter (QUART) featuring 16-byte transmit and receive FIFOs with an integrated infrared encoder/decoder. It supports data rates up to 5 Mbit/s at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V. The device operates within the industrial temperature range and utilizes a 64-lead LQFP package. It provides automatic hardware or software flow control, DMA mode transfers via trigger levels, and internal loop-back diagnostics.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

Quad UART architecture with 16-byte FIFOs for each channel
Integrated infrared (IrDA) encoder and decoder
Automatic hardware and software flow control capabilities
Internal loop-back functionality for diagnostic testing

UARTs (Universal Asynchronous Receiver Transmitter) Applications

Serial data communications in industrial environments
High-speed modem interfaces requiring fast data processing
Shared network systems demanding efficient multi-channel management

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through official manufacturer channels due to discontinued status. Confirm material declarations and environmental compliance against specific ordering suffixes. Ensure compatibility with existing system designs as this part is no longer manufactured.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when pin compatibility with ST16C554 or TL16C554 is required. Consider the LQFP64 package constraints which limit interface modes to 16-bit Intel style only. Evaluate power supply requirements across 2.5 V, 3.3 V, and 5 V options for optimal performance.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This QUART belongs to the SC16C554/554D family, designed as an upward solution to the standard 16C454. It offers enhanced features like larger FIFOs and IrDA support while maintaining downward compatibility with legacy 16C454/554 devices upon reset.
