TL16C2550IRHBG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2550IRHBG4 is a dual universal asynchronous receiver-transmitter (UART) interface 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 a maximum data rate of 1.5 Mb/s and operates within a supply voltage range of 1.8 V to 5.5 V. It utilizes a 32-pin VQFN package suitable for surface-mount applications. The component functions across an industrial temperature range from -40°C to +85°C and includes internal clock generation capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS standards before procurement. Confirm availability status as discontinuation notices may affect long-term supply. Ensure design-in compatibility with existing PCB footprints for the VQFN-32 package. Validate that the 1.8V to 5.5V operating range matches the target system power rails.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART ports are required in a compact form factor. The 16-byte FIFO depth is suitable for moderate data throughput applications without complex DMA controllers. Consider the VQFN-32 package constraints for thermal management and board space. Verify that the 1.5 Mb/s maximum speed meets the baud rate requirements of the connected peripherals.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C2550 family of dual UART interface ICs. It serves as a legacy-compatible replacement for older STMicroelectronics ST16C2550 and NXP SC16C2550 devices. The G4 suffix denotes a lead-free version compliant with European Union directives. It provides a drop-in solution for designs migrating from previous generations of dual UART controllers.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-to-pin replacements include the TL16C2550IRHBR for tape-and-reel packaging or the TL16C2550PFB for TQFP packages. Legacy equivalents such as the ST16C2550 and SC16C2550 offer functional compatibility but require verification of electrical specifications.
