Smart Home Appliances

IoT / Wearable Device

USB Peripherals

Data Processing / Logger

Increasing home appliances now require 32-Bit processing - for example intelligence or connectivity

Trends for wearable devices is increasing demand for lower power 32-Bit MCUs.

USB is still the most widely used interface and is a necessary feature of PC related products.

Higher data processing demands require power of 32-Bit processor for calculations.

Intelligent Toys Higher level toys require 32-Bit MCUs for computing power and cost effectiveness.
