SC16C850VIBS,157

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C850VIBS,157 is a single-channel Universal Asynchronous Receiver/Transmitter (UART) designed for serial data communications. It operates at 1.8 V and supports data rates up to 5 Mbit/s with an external clock or 1.5 Mbit/s using a crystal. The device features 128-byte transmit and receive FIFOs to reduce CPU bandwidth requirements. It includes an Intel XScale processor VLIO interface, IrDA encoder/decoder, and modem control functions. Operating within an industrial temperature range of -40 °C to +85 °C, it is housed in an HVQFN32 package.
