TL16C2550PFBR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2550PFBR is a dual universal asynchronous receiver-transmitter (UART) manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5.5 V and supports data rates up to 1.5 Mbps. The device integrates two independent UART channels, each equipped with 16-byte transmit and receive FIFOs to enhance throughput and reduce CPU overhead. It is housed in a 48-pin Thin Quad Flatpack (TQFP) package with a 7x7 mm footprint. The component is designed for industrial applications, supporting an operating temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture providing two independent UART interfaces within a single package
• Integrated 16-byte FIFOs on both transmit and receive paths to minimize processor intervention
• Wide supply voltage compatibility ranging from 1.8 V to 5.5 V for flexible system integration
• Supports high-speed asynchronous communication with data rates reaching 1.5 Mbps

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial communication ports
• Embedded control units needing reliable asynchronous data transfer
• Telecommunications equipment utilizing dual-channel serial interfaces
• Automotive electronic modules operating under extended temperature conditions

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix PFBR indicates tape-and-reel packaging when sourcing components. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check for RoHS compliance status if environmental regulations apply to the assembly process. Ensure the operating temperature grade matches the intended application environment requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality is required in a compact surface-mount form factor. The 1.8 V to 5.5 V input range allows direct interfacing with various logic levels without additional level shifters. Consider the 48-TQFP package dimensions for PCB layout constraints. Verify that the 1.5 Mbps maximum data rate meets the bandwidth requirements of the target serial protocol implementation.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The TL16C2550 series represents a family of dual UARTs from Texas Instruments. The TL16C2550PFBR specifically denotes the industrial temperature grade variant in a TQFP package. Other variants include the TL16C2550PFB for commercial temperatures and the TL16C2550IRHB for different packaging options. This part shares core functional specifications with the broader TL16C2550 family while differing in thermal performance and physical enclosure.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-compatible replacements within the same package include other TL16C2550 variants such as TL16C2550PFB or TL16C2550IPFBR. Cross-brand alternatives require verification of register compatibility and electrical characteristics. Ensure any substitute maintains the 16-byte FIFO depth and 1.5 Mbps speed capability.
