TL16C550DPFB

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550DPFB is a single-channel asynchronous communications element (ACE) manufactured by Texas Instruments, housed in a 48-pin Thin Quad Flatpack (TQFP) package. It supports operation with supply voltages of 5 V, 3.3 V, and 2.5 V. The device features 16-byte receive and transmit FIFOs to reduce CPU overhead. It accommodates baud rates up to 1.5 Mbaud with a 24-MHz clock at 5 V, or up to 3 Mbaud with a 48-MHz clock at 3.3 V. The component includes programmable auto-RTS and auto-CTS autoflow control, independent interrupts, and full modem control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

Programmable autoflow control utilizing auto-RTS and auto-CTS mechanisms to manage serial data flow automatically.
Integrated 16-byte receiver and transmitter FIFOs for buffering data and minimizing software management overhead.
Complete set of standard asynchronous communication bits including start, stop, and parity generation and detection.
Fully prioritized interrupt system allowing independent control of transmit, receive, line status, and data set interrupts.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

Serial-to-parallel and parallel-to-serial data conversion between CPUs and peripheral devices.
Implementation of DMA controller signaling via TXRDY and RXRDY outputs.
Direct driving of RJ11 cables for serial and modem control outputs.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product folder to confirm pinout compatibility and voltage specifications. Ensure that the selected variant matches the required package type and operating temperature range for the intended design environment.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a functional upgrade from the TL16C450 is required with support for higher baud rates and multiple voltage domains. Consider the 48-pin TQFP package constraints and ensure the application utilizes the available chip select signals (CS0, CS1, CS2) compatible with this package configuration.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The TL16C550D series serves as a speed and operating voltage upgrade to the TL16C550C ACE. It maintains functional equivalence to the legacy TL16C450 on power-up while offering enhanced performance. The PFB suffix specifically denotes the 48-pin TQFP package variant within the broader TL16C550D family.
