Winbond RAM and Ambiq SoC reduce power needs for intelligent wearables
Memory supplier, Winbond Electronics has collaborated with Ambiq, to combine the former’s HyperRAM and the latter’s Apollo4 SoC to deliver low power system solutions for IoT endpoints and wearables.
Dialog Semiconductor uses low power flash memory to increase hearable lifetimes
Reducing the footprint of a hearable device, such as an ear bud, by using smaller batteries can come at the cost of shorter runtimes between recharges, advises Dialog Semiconductor. Hearable devices frequently read data to support advanced functionality such as connectivity, auto-pairing, charge cradle data exchange and equalisation. Dialog Semiconductor has developed the AT25SL128A Flash to minimise power consumption. It features low power, 1.8 V operation, fast read, low profile wafer level chip scale packages (WLCSPs) and is intended for small IoT devices like hearables.
Proximity sensor reduces power consumption in wearables
Power consumption is reduced to just 6.63 microA by the Optoelectronics Group of Vishay Intertechnology in its VCNL36825T integrated proximity sensor. The surface mount package measures 2.0 x 1.25 x 0.5mm. It has a vertical-cavity surface-emitting laser (VCSEL) and a 1.6mm light hole. The sensor is suitable for space-constrained battery-powered applications can be used in consumer and industrial applications, such as true wireless stereo (TWS) and virtual reality / augment reality (VR / AR) headsets. The sensor has a range of 200mm, which means it also provides collision detection in toys and consumer and industrial robots.
