ST16C650ACQ48TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C650ACQ48TR-F is a single Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by MaxLinear, Inc. It is housed in a 48-lead Thin Quad Flat Package (TQFP) with a 7x7 mm footprint. The device provides one full-duplex communication channel and includes an internal 64-byte First-In-First-Out (FIFO) buffer for both transmit and receive operations. It supports standard asynchronous serial protocols and operates within a specified voltage range to interface with various digital systems.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates a 64-byte FIFO buffer to enhance data throughput and reduce CPU intervention during serial communication.
• Provides a single full-duplex UART channel for asynchronous data transmission and reception.
• Designed for compact system integration utilizing a 48-pin TQFP surface-mount package.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring reliable serial data exchange
• Embedded devices needing UART connectivity for configuration or telemetry
