Smart Watch

Overview

Comfort, compact, fashionable, rich user experience, low power consumption and performance efficiency are just a few requirements of smart watch designers.

With a broad portfolio of sensors, connectivity, security and embedded processing, NXP's technology is designed to meet the growing and demanding need of smart watch designs. Take the i.MX RT500 family of crossover MCUs for example. This family of MCUs is optmimized for low-power HMI application by combining a graphics engine and a streamlined Cadence^® Tensilica^® Fusion F1 DSP core with a next-generation Arm^® Cortex^®-M33 core.
