SC16C850SVIBS,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C850SVIBS,151 is a single-channel Universal Asynchronous Receiver and Transmitter (UART) operating at 1.8 V with an Intel XScale processor VLIO interface. It supports data rates up to 20 Mbit/s using programmable sampling rates of 16x, 8x, or 4x. The device features 128-byte transmit and receive FIFOs to reduce external CPU bandwidth requirements. It includes IrDA encoder/decoder support, modem control interfaces, and automatic RS-485 driver turn-around. The component is housed in an HVQFN32 package and operates within an industrial temperature range of -40 °C to +85 °C.
