STMicroelectronics has rolled out a line-up of microcontroller chips geared to deliver the same high-performance graphics allowing intuitive smartphone-like user interfaces in wearable devices, smart appliances and other Internet of Things (IoT) applications. According to the company, the STM32F469/479 devices provide this level of performance through the combination of ST's Chrom-ART Accelerator and the MIPI-DSI technology that is widely deployed in today's smartphones and tablets, without higher cost or shorter battery runtimes.

Paving the way to enabling "smart objects" such as wearable fitness aids or intelligent home appliances, the product line combines leading real-time processing performance with extended connectivity to deliver to these applications the benefit of software ecosystems such as application stores that are increasingly part of everyday life, ST indicated.

At the heart of the product line is a 32bit low-power ARM Cortex-M4 MCU core 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 programme memories. Through the combination of the accelerators and the MIPI-DSI interface, the MCU performs the demanding real-time system control, monitoring and application tasks that would otherwise require even more powerful, and more power-hungry, processors, ST said.

Minimising power extends operating time without a battery recharge, and shrinking circuits allows equipment makers to meet the ever-increasing 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 company added.

The STM32F469/479 MCUs are sampling to lead customers and volume production is scheduled for 3Q15. Budgetary pricing starts at $8.29 for the STM32F469AEH6 with 512KB Flash Memory in the BGA 169 package in volumes of 10,000 units.
