Secured Cortex M4F MCUs run at 4μA/MHz
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’s IoT network to offer LoRaWAN direct-to-satellite connectivity
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 ...
High-side mosfet load switch driver is 1.2 x 0.8mm
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’s bidirectional satellite IoT service launches commercially
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 – ...
