Sub-threshold IC company Ambiq has announced two low-power microcontrollers for IoT end-points, one with Bluetooth. They are Apollo4 Plus and Apollo4 Blue Plus, both with an Arm Cortex-M4 core (up to 192MHz, with floating point), up to 2Mbyte MRAM (4μA/MHz operation executing from MRAM, with cache) and up to 2.75Mbyte of SRAM. The ‘Blue’ version also has a Bluetooth Low Energy 5.1 ...
Lacuna Space has announced an agreement with Omnispace to collaborate on an IoT service that will use LoRaWAN to enable direct-to-satellite communications for an IoT devices. The idea is for satellite coverage to fill connectivity gaps in hard-to-reach areas that are without cellular or Wi-Fi signals. It is planned for the service to be available to customers and distribution partners in ...
Toshiba has introduced a mosfet load switch gate driver in a 1.2 x 0.8 x 0.35mm 6bump WCSP6G the chip-scale package, suiting it to wearables and smartphones, it said. The IC, called TCK421G, can separately drive the gates of a pair of back-to-back n-channel mosfets to make a reverse-blocking switch – useful when multiplexing power sources. If reverse blocking is not needed, ...
Astrocast has made its bidirectional satellite IoT service commercially available, aimed at connecting IoT devices globally for use outside of cell-based terrestrial networks. The service uses Astrocast’s own recently launched nanosatellite constellation, in Low Earth Orbit, and it is bidding to support low-cost applications in asset tracking and telemetry. Target sectors include agriculture and livestock, utilities, transport and mining – ...
Some new Arduino hardware is coming to town, joining the Arduino PRO Portenta family: the Portenta Cat M1/NB IoT GNSS Shield
Toshiba has launched tiny load switches for wearables and IoT that consume only 80pA quiescent current – the Electronics Weekly calculator makes that 300,000 years from a CR2030 coin cell. They come in the company’s 0.65mm x 0.65mm WCSP4G package that is only 0.45mm and can switch up to 1A (2A pulsed). On-resistance varies from 46mΩ running at 5.5V, to 343mΩ ...
