Microcontrollers add smartphone-like graphics to wearables

Microcontroller chips designed to bring the same graphics-enabling, intuitive smartphone-like user interfaces in the world of wearable devices, smart appliances, and other IoT (Internet of Things) applications, says STMicroelectronics.

The STM32F469/479 microcontrollers combine Chrom-ART Accelerator and the MIPI-DSI technology, without higher cost or shorter battery-lifetime penalties, says the company.
Paving the way to wearable fitness aids or intelligent home appliances, they combine real-time processing with extended connectivity to deliver software ecosystems such as application stores.
The 32bit low-power ARM Cortex-M4 MCU (microcontroller unit) core is augmented by the Chrom-ART Accelerator and ART Accelerator that speed up graphics and real-time processing as well as access to the MCU’s program memories.
Minimising power extends operating time without a battery recharge, and shrinking circuits allows equipment makers to meet the consumer demand for smaller and lighter products.
The STM32F479 devices also include an embedded cryptographic co-processor for applications where high security is required.
The microcontrollers are sampling now and volume production is scheduled for Q3 2015.
