TL16C550CPFBR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550CPFBR is a single-channel asynchronous communications element (ACE) manufactured by Texas Instruments. It features 16-byte transmit and receive FIFOs with error status bits, supporting data rates up to 1 Mbaud with a 16-MHz clock. The device operates on 3.3-V or 5-V supplies within a commercial temperature range of 0°C to 70°C. It utilizes a 48-pin PFB (TQFP) surface-mount package. Key specifications include programmable baud rate generation, independent interrupt control, and autoflow capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Autoflow control using programmable auto-RTS and auto-CTS modes to manage serial data flow and prevent overrun errors
• Integrated 16-byte transmit and receive FIFOs that reduce CPU software overhead during high-speed communication
• Complete modem control interface supporting standard signals including CTS, RTS, DSR, DTR, RI, and DCD
• Fully prioritized interrupt system with independent control for transmit, receive, line status, and data set events

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Serial-to-parallel and parallel-to-serial conversion in embedded systems
• Interfacing DSPs or microcontrollers with personal computers via RS-232 or similar protocols
• Industrial equipment requiring reliable asynchronous data transmission with hardware flow control

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'PFB' confirms the 48-pin Thin Quad Flatpack variant. Confirm the 'R' suffix indicates reel packaging. Ensure the operating voltage matches the target 3.3-V or 5-V design requirements. Check the temperature grade against the application environment constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with integrated FIFOs is required. It serves as a functional upgrade to the TL16C450 and TL16C550B. Choose this part if autoflow control is needed to minimize CPU intervention. Verify pin compatibility if replacing legacy ACE designs.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This device belongs to the TL16C550C family of asynchronous communications elements. It functions as a direct software-compatible replacement for the TL16C450 while offering enhanced FIFO buffering. The family includes variants with different packages and temperature ratings to suit various industrial and commercial applications.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C550DIPT is a compatible alternative featuring identical functionality but housed in a 48-LQFP package instead of the TQFP format.
