TL16C2552IFN

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2552IFN is a dual universal asynchronous receiver/transmitter (UART) manufactured by Texas Instruments. It operates within a supply voltage range of 1.8V to 5.5V and supports data rates up to 1.5 MB/s. The device features two independent channels, each equipped with a 16-byte FIFO for efficient data buffering. It utilizes an 8-bit external data bus and a 3-bit address bus for system integration. The component is housed in a 44-pin PLCC package and is rated for operation between -40°C and +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture providing independent asynchronous serial communication paths
• Integrated 16-byte transmit and receive FIFOs per channel to reduce CPU overhead
• Wide supply voltage compatibility supporting 1.8V, 2.5V, 3.3V, and 5V systems

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring multiple serial ports
• Embedded computing platforms needing high-speed UART expansion
• Telecommunications equipment utilizing asynchronous data transfer

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IFN' against the manufacturer's current datasheet to confirm pinout and package dimensions. Ensure the operating environment falls within the specified temperature range. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual UART interface is required with moderate data throughput capabilities. The 16-byte FIFO depth is suitable for applications where burst data handling reduces processor interrupt frequency. Verify that the host system supports the necessary address decoding logic for the 3-bit address bus configuration.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C255x family of UART controllers from Texas Instruments. It serves as a legacy-compatible replacement for older NS16C2552 designs while offering improved low-voltage operation. The IFN designation specifically indicates the plastic leaded chip carrier package variant used in surface-mount assemblies.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C2552FNR is a reel-packaged alternative within the same functional family. Cross-reference pinouts carefully as packaging differences may affect board layout requirements without changing electrical functionality.
