NXP Introduces Microcontrollers for the Growing Sensor-Processing Market


NXP Semiconductors N.V. has unveiled the LPC54100 series of microcontrollers, an innovation, the company says in ultra-low power performance for "always-on" sensor processing. With patented architectural innovations, the series will consume an average of 20 percent less power than its closest competitors.

Designed for always-on applications, the LPC54100 series requires as little as 3µA for continuous sensor listening.  Its asymmetric dual-core architecture enables scalable active power/performance that enables developers to optimize power efficiency by using the 55 µA/MHz Cortex-M0+ core for sensor data collection, aggregation, and external communications, or the Cortex-M4F core (100 µA/MHz) to execute math-intensive algorithms (i.e., motion sensor fusion) more quickly while saving power.

This architecture is complemented by a range of analog and digital interfaces designed from the ground up for power efficiency "” including a 12-bit, 4.8 Msps ADC capable of full-spec performance at the full voltage range (1.62 to 3.6 V), as well as low-power serial interfaces "” enabling the LPC54100 series to offer the lowest power consumption for sensor processing than any other microcontroller in its class.

"The advanced features appearing in mobile devices today such as context-, location-, and environment-awareness; motion-, touch-, and gesture-based interaction, even voice activation are made possible by the growing number of "˜always-on' sensors," said Jim Trent, vice president and general manager, microcontrollers business line, NXP Semiconductors. "In the near future, other industries will make similar strides by requiring mobile phone product features to enhance their customer's experience. Today, many older MCU sensor-processing architectures are just too power hungry or do not scale efficiently as the number of sensors increase. The LPC54100 series enables any industry to benefit from the smarter, more user-centric experience that sensors can bring."

The LPC54100 Series targets products in mobile, wearable health/fitness, industrial applications (environmental monitoring, home and building automation lighting, and robotics), gaming, or other use cases that require long battery life as a key driver to enhance the end-user experience.

To enable embedded developers to bring sensor-based designs to market quickly, NXP partnered with strategic manufacturers and sensor-processing middleware providers, including Bosch Sensortec, CyWee Motion, Hillcrest Labs, and others. NXP has also partnered with Bosch Sensortec to offer an application-in-a-box Sensor Processing/Motion Solution that combines an LPC54102 microcontroller, nine popular sensors, including Bosch Sensortec's motion and pressure sensors and sensor fusion middleware, and NXP's LPCXpresso development platform and support.
