TL16C2552IFNR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2552IFNR is a dual universal asynchronous receiver transmitter (UART) integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 1.62 V to 5.5 V, supporting low-power applications. The device features two independent channels with 16-byte transmit and receive FIFOs for efficient data handling. It supports data rates up to 1.5 MB/s and functions across an operating temperature range of -40°C to +85°C. The component draws a typical operating current of 7.5 mA and is housed in a PLCC-44 surface-mount package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture providing independent UART interfaces
• Integrated 16-byte FIFOs for both transmit and receive operations
• Wide supply voltage compatibility from 1.62 V to 5.5 V
• Supports high-speed data transmission up to 1.5 MB/s

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring dual serial ports
• Embedded controllers needing low-voltage UART connectivity
• Data acquisition modules with moderate baud rate requirements

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IFNR' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the PLCC-44 package dimensions align with your PCB footprint. Confirm RoHS compliance status if required by your manufacturing standards. Check for any recent obsolescence notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual UART interface is needed with support for voltages as low as 1.62 V. The 1.5 MB/s data rate capability suits applications beyond standard 115.2 kbps needs. Consider the PLCC-44 package constraints during layout. Compare against single-channel alternatives if only one port is necessary to optimize board space and cost.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C25xx family of UART controllers from Texas Instruments. It shares architectural similarities with other members like the TL16C552 but offers extended voltage ranges and higher speed capabilities. The IFNR designation indicates a specific tape-and-reel packaging variant suitable for automated assembly processes in high-volume production environments.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include the TL16C2552IFN. Verify pin compatibility and electrical specifications before swapping. Other family members may require adapter circuits or firmware adjustments due to differing register maps or voltage tolerances.
