STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, and Tapko Technologies, a leader in KNX solutions for home and building control, have released a KNX communication stack for all ST’s STM8 and STM32 microcontrollers. This initiative will speed up development of smart-building systems for automatic lighting, heating and other environmental controls that help enhance energy efficiency and user comfort.

The move addresses a market estimated at over EUR 600 million in Europe alone, and allows engineers to leverage the advanced capabilities of ST’s STM8 and STM32 microcontroller families for innovative residential or commercial building-automation products. Over 500 variants are available, including ultra-low-power STM8L and STM32L devices, maximizing freedom to optimize price, power consumption and functionality.

KNX is currently used in over 70% of European smart-home devices. As an open standard, KNX promotes interoperability, saves costs and enhances flexibility for product developers and equipment owners. Now managed by the KNX Association, it is ratified as CENELEC EN 50090 or CEN EN 13321-1 in Europe, GB/Z 20965 in China, ANSI/ASHRAE 135 in the USA, and globally as ISO/IEC 14543-3.
