TL16C2550IPFBR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2550IPFBR is a dual universal asynchronous receiver-transmitter (UART) integrated circuit 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 features two independent UART channels, each equipped with a 16-byte FIFO buffer for efficient data handling. It is housed in a 48-pin Thin Quad Flatpack (TQFP) package with dimensions of 7x7 mm. The component is designed for surface-mount installation and functions reliably across an industrial temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the complete part number including the suffix 'R' which indicates tape-and-reel packaging. Confirm that the specific revision matches the design requirements. Check for RoHS compliance status as manufacturing processes may vary. Ensure the supplier provides original manufacturer documentation. Validate the package type is indeed 48-TQFP before integration into the PCB layout.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UARTs are required in a single package. The 16-byte FIFOs are suitable for applications with moderate data throughput. Consider the 48-pin TQFP footprint for board space constraints. Verify that the 1.8 V to 5.5 V input voltage range aligns with the system power rails. Evaluate thermal performance within the -40°C to +85°C operating range.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C2550 family of dual UARTs from Texas Instruments. It serves as a successor or alternative to legacy components like the ST16C2550 and SC16C2550. The family offers pin-compatible options in various packages such as VQFN and TQFP. It is widely used in embedded designs requiring multiple serial ports without increasing component count.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct replacements include TL16C2550IPFB and TL16C2550IPFBG4. These variants share identical electrical characteristics and pinouts. The 'G4' suffix denotes lead-free and RoHS-compliant construction. Verify package dimensions and thermal properties when substituting.
