TL16C554APN

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C554APN 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 operates within a supply voltage range of 3V to 5.25V and supports maximum data rates up to 1 Mbps. It is housed in an 80-lead Low-Profile Quad Flat Package (LQFP) measuring 12x12 mm. Key functional attributes include automatic flow control, modem control signals, and false start bit detection capabilities.
