TL16C554APNG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C554APNG4 is a quad universal asynchronous receiver transmitter (UART) integrated circuit manufactured by Texas Instruments. It features four independent UART channels, each equipped with a 16-byte FIFO buffer to enhance data throughput and reduce processor overhead. The device supports data rates up to 1 Mbps and operates within a supply voltage range of 3V to 5.25V. It is housed in an 80-pin LQFP package measuring 12x12 mm. Key functional capabilities include automatic flow control, modem control signals, and false start bit detection, making it suitable for complex serial communication applications requiring multiple ports.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels with dedicated 16-byte FIFOs for efficient data handling
• Supports automatic hardware flow control and standard modem control signal interfacing
• Includes false start bit detection logic to improve communication reliability in noisy environments

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multi-port serial connectivity
• Embedded controllers expanding serial interfaces for peripheral devices

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence when sourcing. Confirm the package type matches the required 80-LQFP footprint for PCB design. Ensure the operating voltage requirements align with the 3V to 5.25V specification before integration into the target system design.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four distinct UART interfaces are needed within a single IC footprint. The 16-byte FIFO depth is sufficient for moderate data rates up to 1 Mbps. Consider the 80-pin LQFP package constraints regarding board space and thermal dissipation compared to lower pin-count alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C554 family of asynchronous communication elements. It serves as a high-density solution for replacing multiple discrete UART chips or lower-channel-count ICs. The device is designed to interface directly with microprocessors and digital signal processors via an 8-bit parallel data bus.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C554AIPNR is a parameter-equivalent alternative within the same family. Verify pin compatibility and package dimensions when substituting, as both utilize the 80-LQFP form factor but may differ in specific suffix designations regarding environmental compliance.
