Maxim adds ECC memory to Cortex-M4, and cuts power

Maxim has added error-code correction (ECC) to both flash, RAM and cache in a increased-reliability microcontroller for industrial, healthcare and IoT use. Called MAX32670, it is built around an Arm Cortex-M4 with floating-point unit, and this EEC is capable of single error correction and double error detection. “In many industrial and IoT applications, high energy particles and other ...

A new approach to skin chemistry sensing

Engineers at University of California Los Angeles have found a way to create a stretchable adhesive skin chemistry sensor without serpentine electrical conductors. Instead, they persuaded the liquid sweat to move sideways through the film – maintaining stretchability – while electrical connections are made through the thickness of the sensor to a rigid electrode array at the ...

SlothBot: Grown up, but still hanging around

Georgia Tech’s SlothBot concept has been turned into a demonstrator, that will hang around in the canopy of Atlanta Botanical Garden monitoring temperature, weather, and carbon dioxide levels. The concept was modelled on real sloths – animals that hang from branches and move slowly to conserve energy. “SlothBot embraces slowness as a design principle,” said GaTech ...

Rohm’s 4th gen 1.2kV SiC mosfets

Rohm has announced a 4th generation of 1.2kV silicon carbide mosfets, honing them for driving the traction motors of electric vehicles as well as industrial equipment power supplies. “For power semiconductors, there is often a trade-off between lower on-resistance and short-circuit withstand time,” said the company. “Rohm was able to improve this relationship and reduce ...

Linear position sensor works with rotating tilting target

CambridgeIC has added axial linear position sensing of rotating targets to the list of sensing capabilities available from its products. “The sensors are unique in measuring the continuous position of a freely rotating wireless target, from the side, and with a big gap, and without interference from nearby magnets,” according to the company. “Typically 10 ...

ST moots ways to use Bluetooth wearables for social distancing

STMicroelectronics has released a paper describing ways to combine Bluetooth LE, accelerometers and sub-GHz Sigfox comms in a wearable social distancing node, designed to work with similar nodes. It uses non-connecting Bluetooth modes, measuring signal strength to estimate the proximity of similar devices in real time – acting on three adjustable  virtual ranges: safe (>3m), pre-alert (3m) ...

Isolated RS-485 RS-422 transceiver withstands 5.7kVrms

Analog Devices has introduced RS-485 and RS-422 transceivers that can withstand 5.7kVrms and ±15kV ESD. “The transceivers’ simplified PCB layout and small form factor pack more functionality into space constrained applications than the previous generation,” said ADI. There will be four products: ADM2867E 25Mbit/s full duplex, separate driver and receiver cable inversions pins ADM2865E 25Mbit/shalf ...
