Renesas is claiming “industry’s lowest overall power consumption for general purpose 32-bit MCUs” for its Arm Cortex-M23 based RA0 series. Consumption is 84.3μA/MHz and the company “offers a ‘software stand-by’ mode that reduces power consumption by a further 99% to 0.2 µA”, it said. Wake from this mode is in 4.6μs or less if the internal 32MHz oscillator is used. ...
Resasas has put its in-house developed 32bit RISC-V core into a few-pin general-purpose MCU series, following earlier RISC-V projects with Anders and SiFive. Announced last November, the core implementation can accommodate various standard RISC-V options, to which Renesas has added its own options including: a stack monitor register to protect against rogue software, a dynamic branch prediction unit improve the ...
Renesas has added a 24bit ΣΔ (sigma-delta) ADC to a 48 MHz Arm Cortex-M23 microprocessor, as well as dual-bank code flash for over-the-air firmware updates. “RA2A2 devices offer multiple power structures and voltage detection hardware to realise energy-efficient operation as low as 100µA/MHz in active mode, and 0.40µA in software stand-by mode,” according to the company. “An independent power supply ...
Renesas is aiming at industrial robots with a microcontroller that combines AI vision and real-time control processing. Called RZ/V2H, the ICs include the company’s DRP-AI3 ‘dynamically reconfigurable processor’ AI accelerator – recently revealed at ISSCC in San Francisco – in 10Top/s/W form. “Pruning technology employed in the DRP-AI3 accelerator improves AI computing efficiency, boosting inference performance to 80Top/s,” according to ...
Hitachi and NEC are to sell off their shares in Renesas. Hitachi Semiconductor and Mitsubishi Electric were the founding partners in Renesas in 2002 with NEC Electronics, the semiconductor arm of NEC, joining Renesas in 2010. In 2013, the state-backed fund INCJ took a 69% stake. Since then, Renesas has been a success with its share price rising 13x and ...
Renesas has invented a non-contact industrial rotary inductive position sensor that works up to 600,000rpm and has a propagation delay less than 2μs. This image is part one of the snippets of information available Beyond that, the company is not saying much as the IC (or ICs) is is not scheduled for mass production until Q2 next year. It is ...
Having trawled though Arduino’s just-released Uno R4 literature, here are the Uno R4 WiFi and R4 Minima in a nutshell: Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO connections are in physically similar positions to Uno R3, and IO remains 5V. USB connector changed to Type-C. 6 – 24Vin (barrel jack – higher than ...
Renesas has bought NFC specialist Panthronics AG in an all-cash transaction. The acquisition will enrich Renesas’ portfolio of connectivity technology, extending its reach into high-demand NFC applications in fintech, IoT, asset tracking, wireless charging, and automotive applications. NFC has emerged as a de facto standard in the digital economy and touches many aspects of daily life. Fintech, such as mobile ...
Following its acquisition of Steradian Semiconductors in August, Renesas entered the automotive radar market this week when it introduced a multi-channel 76 – 81GHz transceiver at Electronica. Designed for driver assistance and Level 3 (and higher) autonomous driving, the MMIC (monolithic microwave integrated circuit) is aimed imaging radar, long-range forward radar and ‘4D’ radar, “but can also be used for ...
At Electronica 2022 we caught up with Nathan John, Senior Director of Marketing at Renesas Technology, as part of our promotional coverage for the event. Nathan presents the GreenPAK platform for integration and flexibility. GreenPAK is a broad family of mixed-signal parts enabling designers to integrate multiple discrete components into a single chip reducing current consumption, BOM, cost, and PCB ...
