TL16C2550PFBG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2550PFBG4 is a dual universal asynchronous receiver transmitter manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5 V and utilizes a 48-pin Thin Quad Flat Pack (TQFP) package with an industrial temperature rating of 0°C to 70°C. The device integrates two independent UART channels, each equipped with a 16-byte transmit and receive FIFO buffer. It supports data rates up to 1.5 Mbps and includes hardware auto-flow control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture providing independent serial communication paths
• Integrated 16-byte FIFO buffers for both transmission and reception
• Hardware-based automatic flow control functionality
• Wide operating voltage compatibility from 1.8 V to 5 V

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official documentation. Confirm the specific suffix 'G4' indicates lead-free compliance as per RoHS standards. Ensure the package type matches the required 48-TQFP footprint for PCB integration. Cross-reference the datasheet revision to confirm pinout consistency before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires two independent UART interfaces in a single package. The 1.8 V to 5 V operating range allows flexibility in mixed-voltage system designs. Consider the 16-byte FIFO depth for applications needing moderate buffering without complex software interrupts. Verify that the 0°C to 70°C temperature range meets the environmental requirements of the target application.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C2550 family of dual UARTs. Variants such as TL16C2550PFB and TL16C2550PFBR share identical electrical characteristics but differ in packaging or reel specifications. The 'G4' suffix specifically denotes lead-free construction compliant with European Union directives. This family serves as a drop-in replacement for legacy STMicroelectronics SC16C2550 components.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C2550IPFBRQ1 is a qualified automotive-grade alternative within the same family. Other compatible parts include TL16C2550PFB and TL16C2550PFBRG4, which maintain functional equivalence.
