TL16C2550IRHBR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2550IRHBR 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 Mb/s. The device integrates two independent UART channels, each equipped with a 16-byte FIFO for enhanced throughput. It utilizes an internal oscillator capable of operating at frequencies up to 24 MHz. The component is housed in a 32-pin VQFN package and is rated for an operating temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture providing two independent asynchronous communication interfaces
• Integrated 16-byte transmit and receive FIFOs per channel to reduce CPU overhead
• Supports operation at minimum 1.8 V supply voltage while maintaining functionality at 10 MHz

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring serial communication
• Embedded systems with multiple serial interface needs
• Automotive electronics applications

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments prior to procurement planning.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual UART solution with integrated FIFOs is required for space-constrained designs. Ensure the system logic levels are compatible with the 1.8 V to 5.5 V operating range. Verify that the 32-VQFN package footprint aligns with the PCB layout constraints and thermal requirements of the application.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C2550 family of dual UARTs. It serves as a successor or alternative to legacy components like the ST16C2550 or SC16C2550, offering improved low-voltage operation and integrated FIFOs. The IRHBR suffix specifically denotes the VQFN-32 package variant intended for surface-mount assembly.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Publicly documented substitutes include the TL16C2550IRHB and TL16C2550IRHBR G4. Transitioning from older ST16C2550 or SC16C2550 devices requires reviewing application notes for pinout and register compatibility differences.
