ST16C450CP40-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C450CP40-F is a dual universal asynchronous receiver and transmitter manufactured by MaxLinear. It operates within a voltage range of 2.97V to 5.5V and supports data rates up to 1.5 Mbps. The device integrates 16-byte transmit and receive FIFOs for each channel, enabling full-duplex communication with error flagging capabilities. It features a programmable baud rate generator and four selectable interrupt trigger levels. The component is housed in a 40-pin PDIP package and is designed for industrial applications across a temperature range of -40°C to +85°C.
