TL16C554AIPNR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C554AIPNR 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 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 3 V to 5.25 V. It is housed in an 80-LQFP package measuring 12x12 mm. Key functional capabilities include automatic flow control, modem control signals, and false start bit detection. The component is designed for surface-mount installation and complies with RoHS standards.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix PN against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage levels between 3V and 5.25V. Confirm moisture sensitivity level handling requirements during assembly. Cross-reference the EDA/CAD models provided by Texas Instruments for accurate footprint design. Validate that the selected variant meets all regulatory compliance standards required for the target deployment environment.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single IC must manage four distinct UART connections without external multiplexing. The 16-byte FIFO depth is suitable for applications requiring moderate burst data handling. Ensure the PCB layout accommodates the 80-LQFP package dimensions. Verify that the host microcontroller can interface with the device's address bus and interrupt lines. Consider power consumption constraints given the 3V to 5.25V operating range.
