Updated: More on: Maxim’s AI chip for battery-powered products also adds Risc-V

Earlier today, Maxim announced an AI processing chip for battery-powered devices needing convolutional neural networks (CNNs). What the company has done, is to put custom CNN processing hardware alongside a conventional 100MHz Arm Cortex-M4F core – 4F is the floating point M4 – and squeezed in the added surprise of a 60MHz 32Bit Risc-V core for ...

Global shutter CMOS image sensor for machine vision

ON Semiconductor has introduced a 2.3Mpixel 120frame/s global shutter image sensor for machine vision and mixed-reality displays. Called AR0234CS, te CMOS sensor captures 1080p video and single frames, and “produces crisp and clear images by minimising frame-to-frame distortion in high-speed scenes and reducing the motion artifacts”, according to the company, which also sees the device being used in AR ...

Non-volatile DACs self-configure at power-up

Microchip has announced low-power DACs that self-configure at power-up, using internal non-volatile memory instead of host processor intervention. They are DACs with multiple channels, built-in EEPROM, a built-in reference and an I2C interface: MCP47FEBx4 quad channel MCP47FEBx8 octo channel MCP48 parts have similar functions, but with SPI replacing the I2C interface. There are 8bit, 10bit ...

Selective metal plating of 3D printed plastic

3D printed plastic parts can be accurately nickel plated if the plastic is pre-doped with catalyst before printing, according to scientists from Waseda University, Japan. It is an alternative to a conventional technique, where a plain plastic object is dip-coated with catalyst after manufacture, and then immersed in an electroless metal-plating solution. To improve adhesion, ...

Graphene bolometer detects microwaves best

A superconductor-graphene-superconductor Josephson junction has shown a noise-equivalent power of 7 x 10-19W/√Hz, which corresponds to an energy resolution of a single 32GHz photon, according to an international research team. The bolometer is embedded in a 7.9GHz microwave resonator with >99% coupling efficiency. “Our results establish that two-dimensional materials could enable the development of bolometers with the ...

Stanley Electric tests UV-C leds against Covid-19

In tests conducted with Yamaguchi-University, Stanley Electric has achieved 99.9% ‘inactivation’ of Covid-19 virus SARS-CoV-2 using its aluminium nitride-based 265 nm UV-C leds. Inactivation here, said the company, is defined as the inability to multiply after exposure through damage to DNA and RNA. “10ml of virus solutions [5 x 105 PFU/ml] in dishes were irradiated ...
