ST Microelectronics has introduced what it is calling the world’s smallest digital e-compass — a three-axis magnetometer combined with a three-axis accelerometer on a 2x2mm MEMS chip.
By saving board space on next-generation mobile devices, this device should enable new ultra-miniature, location-aware applications. Micro-electromechanical systems already provide much of the smarts to smartphones, and ST is already a major supplier for devices from Apple’s iPhone to Samsung’s Galaxy. However, a new generation of smartphones and other personal devices will have even less board space.
ST said in a press release that its new LSM303C is 20 percent smaller than previous models, saving just under a square millimeter of board space. That does not seem like much, but it will be welcome for devices such as smartwatches or monitoring bracelets, where space is especially precious.
