Majeed Ahmad explores the latest sensor hub offerings for wearable devices.
Atmel has beefed up its sensor hub offerings for wearable devices with SAM D20 Cortex M0+ microcontroller core to add more functionality and further lower the power bar for battery-operated devices. The SAM D20 MCUs offer ultra-low power through a patented power-saving technique called “Event System” that allows peripherals to communicate directly with each other without involving the CPU.
Atmel is part of the group of chipmakers that use low-power MCUs for sensor management as opposed to incorporating low-power core within the application processor. According to market research firm IHS Technology, Atmel is the leading sensor hub device supplier with 32 percent market share.
Sensor hubs are semiconductor devices that carry out sensor processing tasks — like sensor fusion and sensor calibration — through an array of software algorithms and subsequently transform sensor data into app-ready information for smartphones, tablets and…
