STM32F3 range extended to address high performance applications

STMicroelectronics has extended its STM32F3 MCU family to address applications that require high performance and innovative features at affordable cost. The range now offers memory densities of up to 512kbyte of flash and 80kbyte of SRAM, as well as more capable peripherals for high speed control and off chip storage.

Five UK universities to lead the Alan Turing Institute

The universities of Cambridge, Edinburgh, Oxford and Warwick, along with University College London, will lead the Alan Turing Institute, which will be based at the British Library in London. The Institute is intended to position the UK as a leader in the analysis and application of big data and algorithm research.

Lattice buys Silicon Image in $600m cash deal

FPGA vendor Lattice Semiconductor has signed a definitive agreement to acquire Silicon Image for $600million. Darin Billerbeck, Lattice's president and chief executive officer said the move was a transformative event for both companies. "For the first time in the semiconductor industry, a single company will combine the design flexibility and time to market benefits of FPGAs, with the highly integrated, function and cost optimisation benefits of ASSP solutions."

New class of IGBT reduces switching losses

A new class of low saturation voltage IGBTs specifically optimised for switching frequencies ranging from 50Hz to 20kHz has been announced by Infineon. Applications for the devices are said to include inverters for photovoltaic and welding systems.

Early stage work shows graphene could be used as a semiconductor

A team of researchers from three US universities has demonstrated a way to vary the number of electrons in a give region of a piece of graphene. The team says this is a proof of principle in the creation of semiconductor devices using the so called 'wonder material'. It adds that the number of electrons can be tuned through the application of an electric field and says this could enable future devices to be 'rewired' dynamically.

240MHz RX71M MCUs shipping says Renesas

Renesas Electronics says the RX71M group – the flagship product in the RX Family of 32bit microcontrollers – is now shipping. Developed for use in industrial equipment, the devices run at up to 240MHz and come with up to 4Mbyte of on chip flash.

Kevlar barrier could prevent Li-ion battery fires

A Kevlar based barrier between the electrodes in a lithium-ion battery has been developed by the University of Michigan. The development is believed to prevent fires of the kind believed to have grounded Boeing's 787 Dreamliner in 2013.

Micro ring could hasten the adoption of quantum cryptography

Engineers from Università degli Studi di Pavia have created a micro-ring that entangles individual particles of light. The design is based on a micro ring resonator, a loop etched onto a silicon wafer that can capture and emit particles of light. By tailoring the resonator's design, the researchers created a small and highly efficient source of entangled photons.

USB 3.0 scope range offers 200MHz bandwidth

A range of oscilloscopes from Pico Technology is said to be suited to use by mainstream electronics design engineers. Called the PicoScope 3000D Series, the devices offer bandwidths of up to 200 MHz, two or four analogue channels plus 16 digital channels on the mixed signal models. With memory sizes ranging from 64 to 512Msamples, the scopes offer a maximum real time sampling rate of 1Gsample/s and feature a USB 3.0 interface and a built-in arbitrary waveform generator.

Design and engineering centre opened

Nick Gibb, secretary of state for education, has officially opened a new design and engineering centre at John Warner School, an 11 to 18 comprehensive school in Hoddesdon. The new block will support students at the school in a range of topics, including electronics, robotics and design.

Stable long term operation of graphene devices achieved

Although graphene based devices have shown outstanding electrical and optical performance, they are sensitive to environmental factors, such as humidity or gas composition. This, says a research team, has made reproducible operation in a normal atmosphere impossible.

Top 10 buy 37% of all semiconductors

The top 10 consumer electronics companies bought $125.6billion worth of semiconductors in 2014, equivalent to 37% of all semiconductor purchases and 9.4% more than in 2013, according to a report from market analyst Gartner. Together, Samsung Electronics and Apple bought $57.9bn of semiconductors in 2014, $3.9bn more than in 2013 and equivalent to 17% of total semiconductor demand. However, whilst the top 10 spenders grew their consumption by 9.4%, Apple and Samsung's combined spend grew by 7.1%.
