NXP PCA9698 Demo Board

This add-on to NXP's I2C 2005-1 demo board makes it easy to test and design with the PCA9698, a Fast-mode Plus (Fm+) GPIO device, that provides 40-bit I/O expansion with outputs capable of sourcing 10mA and sinking 25mA with a total package load of 1A.

• Easy-to-use daughter card with comprehensive evaluation software
• Demonstrates a wide range of functions
• 1MHz Fast-mode Plus I2C-bus serial interface with 30mA drive
• Complies with I2C-bus Fast-mode (400kHz) and Standard-mode (100kHz)
• 2.3 to 5.5V operation with 5.5V-tolerant I/O
• 40 configurable I/O pins that default to inputs at power-up
• Designed for live insertion in PICMG applications
• Onboard PCA9530 LED dimmer/blinker for LED applications
• Low standby current
• Temperature range: -40 to +85 °C

The PCA9698 Demo Board contains the NXP PCA9698, four status LEDs, seven user-controllable LEDs, and a high-intensity RGB LED.

The board is designed to quickly set-up, allowing you to explore configuring the PCA9698 with a simple GUI interface. The board's layout provides access to the 40 advanced GPIO pins using standard 0.100" spacing headers. On-board LEDs are present so that the user can visually check the effect of changing register settings in the PCA9698. A user manual is available describing three commonly used configurations:

This demonstration shows you how to use the PCA9698 in GPO mode through turning on and off the on-board LEDs.

In this demonstration, you explore GPIO input using polling mode and interrupt mode.

This colorful demonstration pairs the PCA9698 with a PCA9530 to create a powerful visual experience. The PCA9530 controls the OE pin of the PCA9698, creating eye-catching blinking and dimming patterns.
