TL16C2552FN

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2552FN is a dual universal asynchronous receiver/transmitter manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports data rates up to 1 Mb/s. The device integrates two independent UART channels, each equipped with a 16-byte FIFO for enhanced throughput. It is housed in a PLCC-68 package and functions reliably across an operating temperature range of 0°C to +70°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture supporting independent asynchronous serial communication
• Integrated 16-byte transmit and receive FIFOs per channel to reduce CPU overhead
• Compatible with standard 5-V logic levels and power supplies

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring multiple serial interfaces
• Embedded computing platforms needing high-throughput data logging
• Telecommunications equipment utilizing standard UART protocols

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'FN' corresponds to the PLCC-68 tube packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the 5-V supply requirement aligns with the target system design constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality is required without external multiplexing. Compare against single-channel variants if only one interface is needed to optimize board space. Consider the PLCC-68 footprint requirements during PCB layout planning to ensure adequate clearance for the package dimensions.

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 interface solution for applications transitioning from older parallel ports or requiring robust serial connectivity in industrial environments. The device maintains compatibility with standard UART register sets found in similar industry components.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C2552FNR is the reel-packaged equivalent of this component. Verify pinout compatibility before substituting with other dual-UART ICs from different manufacturers. Check for any differences in FIFO depth or interrupt handling mechanisms when considering alternative parts.
