The University of Lancaster has taken a step forward with its novel non-volatile memory that can be written and erased for one hundredth of the energy needed by flash or DRAM. It is also fast enough to be used instead of DRAM. This article was originally published last week, but without a diagram It is around ...

Microchip has announced what it claims is industry first space-qualified Ethernet transceiver – a radiation-tolerant device based on a COTS (commercial off-the-shelf) chip. Called VSC8541RT, according to Microchip it is a single-port Gigabit Ethernet copper PHY with GMII, RGMII, MII and RMII interfaces. That said, the firm also said “100M limited bit rate VSC8540RT is ...

Panasonic is claiming a record – the world’s smallest 2pole safety relay with power contacts on both normally-open and normally-closed sides. It is 33 x 14.0mm, by 7.8mm tall (including 0.5mm stand-off), and called the SFM series – which have forcibly guided contacts according to EN61810-3. Forcibly guided means that if one contact welds, the other cannot close. ...

Efficient Power Conversion has introduced a 28A 1.2ns laser pulser demonstration and development board built around one if its GaN power transistors. The intended application is ‘time-of-flight’ range measurement, and the chosen GaN transitor (EPC2216 ) is AEC Q101-qualified, allowing the circuit to be used in automotive lidar projects. A novel aspect of this board ...

University of Toronto researchers have developed a stretchy, transparent and self-powering sensor that records the sensations of human skin. It consists of a layer of hydrogel that can converts mechanical stimuli and humidity into variable resistance and capacitance, as well as self-generating power than can be measured as open-circuit voltage or short-circuit current. Hydrogels are ...

A claim that AI could one day deal with on-line trolls could easily be dismissed as vacuous, if it wasn’t coming from the California Institute of Technology. Current ways to detect offensive, harassing, and negative social media posts are either fully automated and not interpretable, or rely on a static set of keywords, which can ...

CML Microcircuits has introduced an evaluation board for its low-power voice codec based around a Raspberry Pi. The codec, the CMX655D, has been built into the EV6550DHAT – a board compliant with Raspberry Pi’s HAT (hardware attached on top) extension board standard. “The Raspberry Pi single board computer is widely recognised by makers, enthusiasts and professional ...

Just before Christmas, Maxim introduced the MAX22701 isolated gate driver intended to drive the gates of fast-switching silicon carbide and gallium nitride transistors. Noise immunity is high, offering a typical common-mode transient immunity (CMTI) of 300kV/µs (fully functioning), plus an isolation withstand voltage of 1.2kVpeak (continuous, 3kVrms for 60s). Devices are available in an 8pin, narrow-body SOIC ...
