Description and Introduction

Remote 8-bit I/O expander for Fm+ I虏C-bus with interrupt and reset The **PCA9672PW** from **NXP Semiconductors** is a versatile **I²C-bus controlled 8-bit I/O expander** designed to enhance system flexibility in microcontroller-based applications. This component provides **remote I/O expansion** via the I²C interface, reducing the need for additional GPIO pins on the host controller.  

With **low standby current consumption**, the PCA9672PW is well-suited for power-sensitive applications. It features **quasi-bidirectional I/O ports**, eliminating the need for direction configuration, and supports **hot insertion** with built-in noise suppression. The device operates across a **wide voltage range (2.3V to 5.5V)**, making it compatible with various logic levels.  

Key applications include **industrial control systems, consumer electronics, and embedded designs** where additional I/O expansion is required. The PCA9672PW also includes **interrupt functionality**, allowing the host to monitor input changes efficiently.  

Available in a **TSSOP16 package**, this I/O expander offers a compact footprint while maintaining robust performance. Its compatibility with **standard I²C protocols** ensures seamless integration into existing designs.  

For engineers seeking a reliable and efficient I/O expansion solution, the PCA9672PW provides a balance of **performance, power efficiency, and ease of implementation**.
