TL16C2550IPFBRQ1

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2550IPFBRQ1 is a dual universal asynchronous receiver transmitter (DUART) integrated circuit manufactured by Texas Instruments. It features two independent UART channels, each equipped with a 16-byte FIFO buffer to enhance data throughput and reduce processor overhead. The device supports data rates up to 1.5 Mbps and operates within a supply voltage range of 1.8V to 5V. It includes an internal oscillator and supports automatic flow control and modem control signals. The component is packaged in a 48-TQFP (7x7 mm) surface-mount case and holds AEC-Q100 qualification for automotive applications.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the complete part number including the Q1 suffix to ensure automotive grade compliance. Confirm the PFBR package variant matches the required 48-TQFP footprint and reel specifications. Cross-reference the manufacturer datasheet revision to ensure compatibility with specific design requirements before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent serial interfaces are required in space-constrained designs. The 1.8V to 5V operating range allows flexibility in system power architecture. Ensure the host microcontroller supports the necessary interrupt and register mapping configurations for efficient FIFO management during high-speed data transfers.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C2550 family of DUARTs. The 'Q1' designation indicates it meets automotive quality standards. The 'IPFB' suffix specifies the 48-TQEP plastic flat package with a 7x7mm body size. It serves as a direct replacement for legacy single-channel UARTs where higher integration and automotive durability are necessary.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for pin-compatible alternatives within the same TI family that may offer different FIFO depths or voltage ranges. Verify that any substitute maintains the 48-TQFP package dimensions and electrical characteristics to avoid PCB redesign.
