NXP® continues its leading position in I2C-bus devices, offering you a vast portfolio for all of your design needs.

NXP’s I/O expander (GPIO) drives LED and monitors switches without using any microprocessor pins.

I2C -bus multiplexers and switches connect an upstream I2C -bus to any combination of downstream I2C busses.

LCD display drivers for a variety of applications. AEC-Q100 qualified versions available

RTCs to suit applications needing accurate time keeping: ultra-low power, high-temperature tolerant, temperature compensated, and high-accuracy

Bridge ICs allow designers to connect together devices that use different serial buses. Interface between standard parallel bus and the serial I2C –bus.

I2C-bus functions for any system. Serial EEProms to store configuration data and DIP switches for replacement of mechanical switches

LED controllers/drivers for blinking, dimming, and color mixing LEDs. Using I2C LED controllers frees the microprocessor for other purposes.

NXP I2C -bus interface temperature sensors offer high-resolution solutions for your thermal management needs – from process control to computing applications.

NXP voltage level translators allow easy connection of I2C signals between a wide range of supply voltage domains.

Buffer I2C signals for a more reliable system and better nosie immunity. Drive I2C signals across a backplane or even further.
