NXP rolls AEC-Q100-compliant GPIO with interrupt and reset

June 13, 2013 // By Christoph Hammerschmidt
Addressing the demand of smart and secure solutions for connecting the car, NXP Semiconductors announced two AEC-Q100-compliant General Purpose parallel Input/Output (GPIO) devices for I2C-bus/SMBus applications. The PCA9538PW/Q900 and PCA9539PW/Q900 are vailable 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.

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