Description and Introduction

40-bit Fm+ I2C-bus advanced I/O port with RESET, OE and INT The **PCA9698BS** from Philips is a versatile **I²C-bus controlled 40-bit I/O expander** designed to enhance system flexibility in applications requiring additional general-purpose input/output (GPIO) ports. This component is particularly useful in scenarios where microcontroller I/O pins are limited, enabling efficient expansion through a simple two-wire serial interface.  

Featuring **40 quasi-bidirectional I/O pins**, the PCA9698BS supports both input and output operations with minimal external components. Each I/O can be individually configured, allowing for precise control in complex systems. The device operates at a **voltage range of 2.3V to 5.5V**, making it compatible with a wide variety of logic levels.  

Key features include **high noise immunity**, **low standby current consumption**, and **hot insertion capability**, ensuring reliable performance in industrial, automotive, and consumer electronics applications. The built-in **interrupt output** pin further enhances functionality by signaling changes on input pins, reducing the need for continuous polling.  

With its **I²C-bus interface**, the PCA9698BS supports fast-mode (400 kHz) communication, facilitating seamless integration into existing designs. Its compact package and robust performance make it an ideal choice for space-constrained and power-sensitive applications.  

In summary, the PCA9698BS offers a scalable, efficient solution for expanding digital I/O capabilities while maintaining system simplicity and reliability.

Description and Introduction

40-bit Fm+ I2C-bus advanced I/O port with RESET, OE and INT The **PCA9698BS** from NXP Semiconductors is a versatile 40-bit I²C-controlled GPIO expander designed to simplify system-level interfacing in complex electronic designs. Featuring an extended voltage range (1.65V to 5.5V), this component is well-suited for mixed-voltage applications, ensuring seamless communication between devices operating at different logic levels.  

With 40 configurable input/output pins, the PCA9698BS offers flexibility for interfacing with sensors, switches, LEDs, and other peripherals. Its I²C-bus interface supports standard (100 kHz), fast (400 kHz), and fast-mode Plus (1 MHz) speeds, enabling efficient data transfer in embedded systems. The device includes interrupt functionality, reducing the need for continuous polling and improving system responsiveness.  

Key features include programmable pull-up/pull-down resistors, output drive strength configuration, and latch-up performance exceeding industry standards. The PCA9698BS is ideal for applications such as industrial automation, consumer electronics, and IoT devices where scalable I/O expansion is critical.  

Housed in a compact TSSOP-56 package, the PCA9698BS provides a space-efficient solution for high-density designs while maintaining robust performance. Its low standby current consumption further enhances energy efficiency in power-sensitive applications.  

For engineers seeking a reliable, high-performance GPIO expander, the PCA9698BS delivers a balance of functionality, flexibility, and ease of integration.
