Introducing the PCA9675PW/S911,118 from NXP

The PCA9675PW/S911,118 is a high-performance, 16-bit General Purpose Input/Output (GPIO) expander produced by NXP Semiconductors. This innovative component is designed to provide additional GPIOs for microcontrollers where additional I/Os are needed, especially in situations where PCB space is at a premium. It operates on the I²C-bus/SMBus, allowing seamless integration with most microcontroller architectures.

Key Features

• Expandability: With the PCA9675PW/S911,118, you can expand your microcontroller's I/O capabilities by 16 additional ports. This is particularly useful for complex systems that require more I/O pins than what is available on the microcontroller itself.
• Compatibility: The device supports both the I²C-bus and SMBus protocols, offering a versatile solution that is compatible with a wide range of microcontrollers and processors.
• Flexibility: Each of the 16 I/O pins can be configured as either an input or an output, providing a flexible interface that can be tailored to a variety of applications.
• Quasi-bidirectional I/Os: This feature eliminates the need for external resistors, simplifying circuit design and reducing component count.
• Power Management: The PCA9675PW/S911,118 includes built-in power-on reset and features a low standby current, making it suitable for power-sensitive applications.

Applications

The PCA9675PW/S911,118 is ideal for a wide range of applications, including:

• Server motherboards
