Tiny low-power Hyperlux LP camera sensors can extend battery life by up to 40%

onsemi has introduced the Hyperlux LP image sensor family for battery-powered industrial and commercial cameras with resolutions from 5MP to 20MP and a low power consumption that can extend battery life by up to 40% based on the company’s internal testing. Three models of the 1.4 µm pixel sensors will initially be offered: the 5MP AR0544, the 8MP AR0830, and the 20MP AR2020. Those camera sensors should eventually be found in a wide range of products such as smart doorbells, security cameras, AR/VR/XR headsets, devices leveraging machine vision, and video conferencing. The AR2020 is a 1/1.8inch Back-Side Illuminated (BSI) Stacked CMOS digital image sensor with a 5120 x 3840 active pixel array with a rolling shutter readout and capable of capturing images in either linear or enhanced Dynamic Range (eDR) modes. Its smaller siblings support the same features, but the AR0830 is a 1/2.9-inch image sensor with a 3840 […]

Nordic nRF54L15 Cortex-M33 wireless MCU halves Rx power consumption over nRF52 chips

Nordic Semiconductor has recently unveiled the 128 MHz nRF54L15 Cortex-M33 multi-protocol wireless microcontroller, the first from the nRF54L Series, and the second from the wider nRF54 family after the more powerful 320 MHz nRF54H20 dual-core Cortex-M33 MCU was introduced last Spring. While the nRF54H20 was designed to enable new types of IoT devices with a leap in performance and lots of resources with up to 2 MB flash and 1MB SRAM, the new nRF54L15 aims to be an upgrade to the nRF52 series with twice the performance and much better power efficiency, with for instance, half the Rx power consumption over its predecessor. Nordic Semi nRF54L15 key features and specifications: CPU Arm Cortex-M33 @ up to 128 MHz with up to 1.5 MB Flash + 256 KB SRAM RISC-V coprocessor for “software-defined peripheral” Wireless Bluetooth 5.4 LE with direction-finding, Bluetooth mesh, etc… Ready for future Bluetooth releases 802.15.4 radio for […]

Sony energy harvesting module generates power from electromagnetic wave noise

Sony Semiconductor Solutions Corporation (SSS) has developed an energy harvesting module that uses electromagnetic wave noise energy to power IoT devices. The new module leverages Sony’s tuner development process to generate power from electromagnetic wave noise from robots inside factories, monitors and lighting in offices, monitors and TVs in stores and homes, etc. in order to provide a stable power supply needed to run low-power IoT sensors and communications equipment. The tiny 7×7 mm module uses the metal parts of electronic devices that serve as the source of electromagnetic wave noise as part of an antenna and employs a rectifier circuit in order to convert electromagnetic wave noise in a range of several Hz to 100 MHz into electrical energy and supply power to low-power consumption IoT sensors and communications equipment or to charge batteries. The module harvests energy from electronic equipment that generates a significant amount of electromagnetic wave […]
