ST ups digital power game with high-end peripherals in Cortex-M4 MCU

STMicroelectronics has created MCU peripherals for improved digital PSUs and motor control: hardware trigonometric and filtering accelerators, a high-resolution timer, a fast analogue comparator and a low-error op-amp. Silicon carbide and gallium nitride converters are a particular target market. Released today, they are all built into STM32G4, a 170MHz Arm Cortex-M4 cored microcontroller – rated ...

Cadence design and sign-oftools for 7nm Arm Cortex-A77

Cadence has announced design and sign-off tools for Arm’s new Cortex-A77 CPU on 7nm processes. The 7nm rapid adoption kit (RAK) provides an RTL-to-GDS flow using Arm 7nm POP IP libraries. “We worked with Arm to optimise our digital implementation and sign-off solutions for the Cortex-A77 so customers can create 7nm designs that meet PPA ...

C&K adds to vandal-resistant switch range

C&K has added a smaller size to its range of vandal-resistant sealed switches for outdoor ATMs, ticket machines and security systems. Called ATP16, the push-buttons fit through a 16mm diameter panel cut-out – and join earlier ATP19 (19mm) and ATP22 (22mm) types. Construction is from a mix of stainless steel, aluminium alloy and the engineering ...

MCU gets high-accuracy analogue front-end for precision industrial sensing

Renesas is claiming 10nV/°C offset drift, 1ppm/°C gain drift and 30nV RMS noise from the analogue front-end (AFE) of its latest microcontrollers “a level that could previously only be achieved by combining dedicated A/D converter circuits with high-precision operational amplifier ICs”, it said. Included monolithically alongside a 32MHz 32-bit RXv2 core, the AFE will appear in ...

Why selenium makes CdTe thin film solar cells better

Selenium-alloyed cadmium telluride solar cells can achieve 22.1% solar cell efficiency, but why? asked a team from Loughborough and Colorado State Universities – particularly when cadmium telluride on its own can only hit 19.5%. The addition of selenium reduces the bandgap, but this is only part of the story, it appears. Cathodoluminescence – turning the ...

TI unveils the fastest 12bit ADC ever

Texas Instruments has revealed the fastest 12bit ADC – the ADC12DJ5200RF – that can sample two channels at 5.2Gsample/s, that can be interleaved into a single 10.4Gsample/s channel. That is two channels of 12bit 2.6GHz instantaneous bandwidth, or one of 5.2GHz instantaneous bandwidth. “The design comes from our centre in Friezing Germany – they have been ...

Locking right-angle IEC mains plug fits in tight spaces

Schaffner has created a right-angled locking IEC C14 plug for space-constrained applications. Part of the firm’s IL13 family “due to its angled construction the connector can be used with devices standing next to a wall or in table-top applications”, said the firm. “All types are usable with any standard IEC C14 inlet, locking without any ...

Optimising AI algorithms can save 10x power

Re-thinking neural network algorithms can deliver 10 times more performance from the same hardware, according to Lattice Semiconductor, which has overhauled its ‘sensAI‘ artificial intelligence-based vision processing intellectual property. SensAI is aimed at edge AI – always-on local pre-processing of images to decide whether more powerful remote processing resources need get involved – reducing the ...
