TL16C554IPN

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C554IPN 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 operates within a supply voltage range of 3V to 5.25V and supports maximum data rates up to 1Mbps. It is housed in an 80-pin Low-Profile Quad Flat Package (LQFP) with dimensions of 12x12mm. The component includes automatic flow control, modem control signals, and false start bit detection capabilities for reliable serial communication.
