Interface - I/O Expanders are integrated circuit chips designed specifically for expanding system input/output (I/O) ports. They are connected to the main controller through serial or parallel interfaces, providing additional I/O pins that allow the system to connect more peripherals or sensors. I/O expanders typically consist of a set of registers, control logic, and necessary driver circuits, supporting multiple input and output configurations such as GPIO (General Purpose Input/Output), PWM (Pulse Width Modulation), I2C, SPI, and other communication interfaces. The design principles of these chips are based on efficient power management and flexible configuration options, which can meet diverse application needs while maintaining low power consumption. I/O expanders include features such as programmability, high integration, low latency, and good electromagnetic compatibility.
Application
Interface - I/O Expanders have demonstrated extensive application value in multiple fields. In embedded system design, they are commonly used as peripheral extensions for microcontrollers (MCUs), providing additional I/O resources to the system to support more sensors, actuators, or other peripherals. In the field of industrial automation, I/O expanders are widely used in PLC (Programmable Logic Controller) systems for monitoring and controlling various equipment and processes on production lines. In addition, in the field of consumer electronics, such as smart homes, smart wearables, and portable electronic devices, I/O expanders also play an important role in helping devices achieve richer functions and higher user interactivity.
