TL16C452FNR TI UART Controller | 68-PLCC (24.23x24.23) | Dual UART, 1Mbps

Product Overview

The TL16C452FNR from Texas Instruments is a dual universal asynchronous receiver/transmitter (UART) integrated circuit designed for serial communication in industrial and embedded systems. It integrates two independent UART channels in a single 68-pin PLCC package (24.23x24.23 mm), providing full-duplex asynchronous communication with data rates up to 1 Mbps. The device is compatible with the industry-standard 16C450 and 16C550 UARTs, offering enhanced features such as programmable baud rate generator, modem control functions, and FIFO buffers for reduced CPU overhead.
