Electronic circuits form a mostly invisible part of the world we live in today. These circuits are present in microchips or just "chips", which combine the latest advances in performance, intelligence and, efficiency. Hundreds or thousands of these chips are integrated into each of the millions and billions of electronic devices people across the globe interact with every day. It is in this unseen realm that STMicroelectronics creates the sparks that animate the products we use at any given moment. Our technology is found everywhere microelectronics makes a positive contribution to people's lives. Chips from ST embedding the most advanced innovations are an essential part of products as diverse as cars and key fobs, giant factory machines and data center power supplies, washing machines and hard disks, and smartphones and toothbrushes. We help our customers make these devices more intelligent, more energy efficient, more connected, safer and more secure.
