Interface - I/O Expanders provide a practical solution for expanding the number of input/output ports available in a microcontroller or microprocessor system. These components enable designers to add more peripherals without the need for additional processing units, thus simplifying circuit design and reducing overall costs.
I/O Expanders, from top manufacturers like Microchip Technology and NXP Semiconductors, come in various types such as SPI, I2C, and GPIO expanders. These devices allow seamless integration with existing systems, enabling efficient control of multiple devices including sensors, displays, and actuators.
Utilizing I/O Expanders increases the versatility and functionality of electronic systems, making them an indispensable component in modern embedded systems design, robotics, and industrial automation.
