For power-sensitive and space-constrained mobile and IoT applications, the SiT3901 uPower digitally controlled MEMS oscillator (DCXO) has been introduced by SiTime. It improves wireless charging speed by up to 25 per cent while reducing the overall timing solution area by up to 90 per cent, says the company. The MEMS oscillator is suitable for wireless charging systems for smart watches, activity trackers, hearing aids, and wearables.

Software packs, tools and eval board accelerate STM32U5 development
Extensions to STMicroelectronics’ STM32 ecosystem accelerate development with the STM32U5 extreme low power microcontrollers. The STM32Cube software packs, tools and evaluation boards are available now and are in stock at authorised distributors.
Smallest Arduino Pro board brings sensing to the edge
Claimed to be the smallest Arduino board to date, Nicla Sense ME has been created by Arduino Pro and Bosch Sensortec. It makes sensing and intelligence at the edge accessible to all, says Bosch Sensortec.
Single chip for remote patient monitoring devices measures four vital signs
Synchronised measurement of ECG (electrocardiogram), heart rate, SpO2 (blood- oxygen saturation) and respiration rate can be achieved using a single chip from Analog Devices. The MAX86178 triple-system vital signs analogue front end (AFE) from Analog Devices has been developed to simplify the design of wearable remote patient monitoring (RPM) devices by measuring four vital signs with a single chip.
