Building on its leadership in smart and secure solutions for connecting the car, NXP Semiconductors today announced the AEC-Q100-compliant PCA9538PW/Q900 and PCA9539PW/Q900 General Purpose parallel Input/Output (GPIO) for I2C-bus/SMBus applications. Available as 8- and 16-bit GPIOs with interrupt output and hardware reset input, these new interface devices now comply with the automotive industry’s stringent AEC-Q100 quality specification and are rated for 4.5V to 5.5V operation.
Along with NXP’s other AEC-Q100 compliant products, the new GPIOs offer many options for designing next-generation body control units, instrument clusters, engine control and car infotainment systems. The PCA9538PW and PCA9539PW devices offer design engineers using the I2C-bus the flexibility of additional I/O port access without the need to replace microcontrollers. Additionally, NXP’s I2C-bus/SMBus-based GPIOs enable seamless migration to newer microcontrollers while allowing design engineers to keep the same peripherals. NXP’s interface products portfolio continues to expand, with over 700 products and over 10,000 customers worldwide.

The introduction of these new AEC-Q100-compliant GPIOs further supports NXP’s vision of connecting the car. From telematics and car-to-x communications to smarter infotainment systems, NXP is creating the devices making the connected car a reality.

Jens Hinrichsen, general manager, Interface Products, NXP Semiconductors, said, “Offering a new GPIO with interrupt output and hardware reset input meets the next-generation design requirements of our customers. By taking existing, market-proven products and putting them through the AEC-Q100 compliance process, NXP has grown its automotive solutions portfolio and has already delivered over 100 million interface product units to the automotive industry.”


The PCA9538PW/Q900 and PCA9539PW/Q900 are both released and shipping in volume.
