ST16C650ACJ44-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C650ACJ44-F is a single Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by MaxLinear, Inc. It provides one channel of asynchronous serial communication with full hardware flow control support. The device integrates a 14-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. It operates within a supply voltage range of 3.0 V to 5.5 V and supports baud rates up to 3 Mbps. The component is housed in a 44-pin TQFP package and is rated for industrial temperature ranges.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates a 14-byte deep FIFO buffer for both transmission and reception to minimize interrupt frequency.
• Supports standard UART protocols including RS-232, RS-485, and RS-422 interface modes.
• Includes comprehensive hardware flow control signals such as RTS, CTS, DTR, and DSR.
• Features an internal oscillator capable of generating precise baud rate clocks without external components.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication.
• Embedded controllers needing high-speed UART interfaces.
