SC16C654BIB64,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C654BIB64,151 is a quad universal asynchronous receiver and transmitter (QUART) manufactured by NXP Semiconductors. It operates at supply voltages of 2.5 V, 3.3 V, and 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 64-byte transmit and receive FIFOs with error flags, automatic hardware or software flow control, and infrared encoder/decoder capabilities. The component is housed in a plastic low profile quad flat package (LQFP64) with 64 leads.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad UART architecture supporting Intel and Motorola bus interfaces

• Integrated infrared (IrDA) encoder and decoder interface

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• High-speed serial data communication systems
• Industrial control and automation networks
• Multi-channel embedded processor interfaces

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix '151' against official documentation to confirm packaging details and compliance status. Confirm availability as this part may be discontinued or subject to last-time buy notices. Ensure the LQFP64 package variant matches the required pin configuration for the target application design.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a quad UART solution with large FIFO buffers is required to reduce CPU overhead. Verify compatibility with either Intel or Motorola bus modes via the 16/68 interface select pin. Ensure the operating voltage aligns with the 2.5 V, 3.3 V, or 5 V requirements of the system design.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C654B/654DB family of quad UARTs. It is functionally equivalent to industry-standard devices like the ST16C654 and TL16C754. The 'B' suffix typically denotes the standard version, while 'DB' variants offer specific internal bonding configurations for interrupt handling on 64-pin packages.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Pin-compatible replacements include the SC16C654DIB64 and the TL16C754APNR. Verify that the substitute device supports the required 64-byte FIFO depth and 5 Mbit/s data rate specifications.
