TL16C550DPFBR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550DPFBR is a single-channel asynchronous communications element (ACE) manufactured by Texas Instruments. It operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 1.5 Mbaud with a 24-MHz clock at 5 V, or up to 3 Mbaud at 3.3 V in specific packages. The device features 16-byte transmit and receive FIFOs with error status bits. It includes programmable baud rate generation, auto-flow control, and independent interrupts. The component is housed in a 48-pin LQFP package and is designed for industrial temperature ranges.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Programmable autoflow control using Auto-RTS and Auto-CTS to manage serial data flow and reduce software overhead.
• Integrated 16-byte transmit and receive FIFOs that buffer characters and include error status tracking.
• Fully prioritized interrupt system allowing independent control of transmit, receive, line status, and data set interrupts.
• Complete modem control capabilities including DTR, RTS, CTS, DSR, RI, and DCD signals.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Serial-to-parallel and parallel-to-serial data conversion in embedded systems
• Modem interface circuits requiring hardware flow control
• Industrial communication links utilizing asynchronous protocols

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the exact ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the procurement channel provides valid traceability for the component. Confirm RoHS compliance status through official datasheets before finalizing orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with hardware autoflow control is required. It serves as a functional upgrade to the TL16C550C and is compatible with existing TL16C450 software drivers. Consider the 48-pin LQFP package for surface mount applications requiring full modem signal availability.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The TL16C550D series represents an evolution of the TL16C550C, offering higher speed capabilities while maintaining register compatibility with the legacy TL16C450. The DPFB variant specifically denotes the 48-pin thin quad flatpack no-lead package configuration used in modern surface-mount designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C550DIPTG4 is a documented equivalent within the same family. Verify pinout and package dimensions when substituting between different package types such as LQFP and TQFN variants.
