A vital technology to simplify any design

As a simple two-wire bus, I²C lends itself to virtually any application, with a broad portfolio of bus enablers and peripherals you'll easily find the device you need at NXP. It could be an LED controller for the enticing lights of gaming machines, a level translator to manage the voltages differences in mobile devices, or a temperature monitor for a blade server. The applications are as varied as NXP's portfolio.

We have created a number of dedicated sample kits to assist you in deciding which components will be most appropriate for your designs. The following application-focused sample kits are now available - for more information on what's in each sample kit simply click one of the above tabs or the links below.

Harness the speed and power of Fast-mode Plus in gaming / vending machines and white goods

Industrial electronics covers a wide range of sub-systems that benefit from I²C technology, including user interface, safety and monitoring, and increasingly complex displays and indicators. And new designs often require higher bus transfer speed for more data bandwidth, and higher drive current for longer buses.

NXP's Fast-mode Plus (Fm+) I²C-bus technology (PCA96xx family) solves these challenges. The simple two signal line I²C-bus greatly simplifies wire congestion in applications from vending machines and industrial control to white goods and kitchen appliances. In addition this higher speed and higher drive I²C-bus technology is supported by NXP's Cortex-M0 family of microcontrollers.

Solve low-voltage logic level challenges in advanced mobile electronics

Battery power and limited space are the two key challenges in mobile electronics, especially with the increasing feature sets on new platforms. Core logic, including processors, operate from lower supply voltages, and consume less power. While this is great for battery life, these components still need to work with existing higher voltage peripherals.

I²C technology not only directly addresses these issues with voltage level translation and easy to add low-voltage I/O capacity, it can also be used for keypad control as well as driving and controlling LEDs.
