SC16C554BIB80,528

Overview

The SC16C554BIB80,528 is a quad Universal Asynchronous Receiver and Transmitter (QUART) manufactured by NXP Semiconductors. It operates at supply voltages of 5 V, 3.3 V, and 2.5 V with an industrial temperature range from -40 °C to +85 °C. The device supports data rates up to 5 Mbit/s at 5 V and 3.3 V, and up to 3 Mbit/s at 2.5 V. It features 16-byte transmit and receive FIFOs with four selectable interrupt trigger levels. The component is available in the LQFP80 package and provides pin and software compatibility with industry-standard ST16C554 and TL16C554 devices.

Feature Summary

Supports both Intel (16 mode) and Motorola (68 mode) bus interfaces for flexible microprocessor integration
Includes 16-byte transmit and receive FIFOs with programmable auto-RTS and auto-CTS hardware flow control
Provides independent prioritized interrupts and complete status reporting capabilities for each channel
Features internal loopback controls for on-board diagnostics and line break generation

Applications

High-speed serial data communications requiring multi-channel support
Systems utilizing shared network environments or high-speed modems
Industrial control applications operating within the specified temperature range

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and electrical characteristics. Ensure the selected variant matches the required interface mode and voltage specifications for the target application design.

Selection Notes

Select this component when a quad UART solution with integrated FIFOs is required for systems needing compatibility with legacy 16C554 designs. Consider the LQFP80 package dimensions and thermal requirements during PCB layout planning.

Part Context

This part belongs to the SC16C554B/554DB family of quad UARTs. It serves as an upward-compatible replacement for the 16C454, offering enhanced performance through larger FIFO buffers and higher maximum data rates compared to standard single-channel UARTs.

Replacement Considerations

The SC16C554BIB80 is functionally equivalent to the ST16C554 and TL16C554. Verify pinout compatibility and register mapping before substituting these components in existing designs.
