SC16C652BIBS,128

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C652BIBS,128 is a dual-channel Universal Asynchronous Receiver and Transmitter (UART) designed for serial data communications. It converts parallel data to serial and vice versa, supporting data rates up to 5 Mbit/s at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V. The device features 32-byte transmit and receive FIFOs with selectable interrupt trigger levels. It includes an infrared (IrDA) encoder/decoder supporting version 1.0, independent programmable baud rate generators, and standard modem control interfaces. Operating within the industrial temperature range of -40 °C to +85 °C, it utilizes a plastic HVQFN32 package.
