| Description | The PCA9535APW,118 is a versatile 16-bit I²C-bus GPIO expander from NXP Semiconductors, designed to provide additional digital input and output capability for microcontrollers and embedded systems. By using a standard I²C or SMBus interface, the device significantly increases available I/O resources while minimizing PCB routing complexity and processor pin requirements. This device provides 16 individually programmable GPIO pins organized into two 8-bit ports. Each pin can be independently configured as either an input or output, offering exceptional flexibility for a wide variety of digital control and monitoring applications. Operating across a wide 2.3V to 5.5V supply voltage range, the PCA9535APW,118 is compatible with both low-voltage and standard logic systems. The device supports 5V-tolerant I/O pins, enabling seamless integration into mixed-voltage environments. The integrated interrupt output allows the host processor to detect input state changes without continuously polling the device. This feature helps reduce processor workload and lowers overall system power consumption, making it ideal for battery-powered and energy-efficient designs. The PCA9535APW,118 incorporates dedicated input, output, polarity inversion, and configuration registers, providing complete control over each GPIO channel. The polarity inversion function allows software-configurable active-high or active-low operation without requiring additional external circuitry. Three hardware address pins enable up to eight devices on a single I²C bus, allowing designers to expand systems to a total of 128 GPIO lines while maintaining a simple two-wire communication interface. The device supports I²C and SMBus communication speeds up to 400kHz. Designed for low-power operation, the PCA9535APW,118 combines minimal standby current with reliable digital performance, making it suitable for portable, industrial, and consumer applications. Its compact 24-pin TSSOP package provides a space-efficient solution for high-density PCB layouts. The PCA9535APW,118 is widely used in industrial automation systems, embedded controllers, IoT devices, communication equipment, consumer electronics, LED control systems, sensor interfaces, building automation products, networking hardware, medical equipment, and microcontroller-based applications requiring additional programmable digital I/O channels. |
