Wed, Sep 09, 2020

Renesas Electronics has added the P9415-R wireless power receiver to its portfolio. The 15W receiver uses WattShare technology and enables smartphones, power banks, and portable industrial and medical equipment, to wirelessly charge other mobile devices and accessories that also have wireless charging capabilities.

The P9415-R features up to 5W of transmit power capability in transmitter/receiver (TRx) mode, as well as receive up to 15W on Qi transmitters, enabling quick and convenient mobile device charging on the go.

Renesas believes the P9415-R will bring WattShare technology to a wider audience. It combines receiver and transmitter capabilities, allowing smartphones, smart watches, wireless ear buds and other devices to be wirelessly charged simply by placing them on top of a smartphone or other industrial and medical portable devices.

In WattShare TRx mode, the P9415-R enables these mobile devices to change the power flow direction and deliver up to 5W of power to charge other devices. Customers can use the same wireless power coil and same P9415 circuitry to both receive and transmit power wirelessly.

The P9415-R wireless power receiver has an MTP non-volatile memory for easy firmware and device function updates. It also has graphic user interface (GUI) support for user customisation.

It receives up to 30W in proprietary mode and has under voltage lockout down to 2.7V which increases the available charging area and connection times. Sensory accuracy has been improved compared with earlier devices in Renesas’ wireless portfolio to increase foreign object detection capabilities.

The receiver also has bi-directional communications to support proprietary authentication with encryption and x-y alignment circuitry for better receiver/transmitter device alignment.

It is also Renesas’ first WPC 1.3-ready wireless power receiver based on the Wireless Power Consortium’s latest inductive standard.

Renesas produces both the power receivers (PRx) used in smartphones and other applications, as well as the power transmitters (PTx) used in charging pads and automotive in-car applications.

The P9415-R 15W WattShare wireless power receiver is available now.

IAR Embedded Workbench supports Renesas’ low-power RE MCU family

Wed, Sep 09, 2020

For embedded design using the code optimisations and debugging features in Arm tools, the IAR Embedded Workbench will speed up development of low-power IoT applications based on the Renesas RE microcontroller (MCU) family, says IAR Systems.

The company announced the update of its development toolchain IAR Embedded Workbench for Arm, with coverage for microcontroller family which is built around an Arm Cortex-M0+ core. The RE is suitable for IoT devices that require low power consumption, such as wearables and sensing applications for homes, buildings, factories and farms or agricultural IoT applications. It reduces power consumption via Renesas’ proprietary Silicon-on-Thin-Buried-Oxide (SoTB) process technology, which reduces power consumption in both active and standby mode, thereby eliminating the need for battery replacement or recharging, says Renesas.

IAR Embedded Workbench for Arm is a C/C++ development toolchain for embedded applications. Developers can use it to leverage advanced code optimisation techniques and power debugging for fast, efficient, compact devices. It has integrated static and runtime code analysis tools for code quality. IAR Systems also offers technical support and services, to support developers as they develop IoT applications which may need the energy harvesting capabilities of the RE microcontrollers.

“IAR Embedded Workbench is well-known for its ability to make the most out of the capabilities of an MCU in an embedded application,” said Anders Holmberg, general manager Embedded Development Tools, IAR Systems. “Coupled with Renesas RE MCUs, the toolchain offers a powerful, yet easy-to-use, solution for developing low-power applications for the IoT space.”

Support for Renesas RE is available using IAR Embedded Workbench for Arm, from version 8.50.6.

IAR Systems supplies future-proof software tools and services for embedded development. Since 1983, IAR Systems’ products have been used in the development of over one million embedded applications.

The company is headquartered in Uppsala, Sweden and has sales and support offices all over the world.

In 2018, Secure Thingz, the global domain expert in device security, embedded systems, and lifecycle management, became part of IAR Systems Group.

SnapDragon and software stack drive ADAS and autonomous systems

Tue, Sep 01, 2020

Automotive software provider, Veoneer and Qualcomm have announced a collaboration to deliver scalable advanced driver assistance systems (ADAS), collaborative and autonomous driving (AD) solutions powered by Veoneer’s next-generation perception and driving policy software stack and Qualcomm’s Snapdragon Ride ADAS/AD scalable SoCs and accelerators. Qualcomm’s portfolio range from L1 to L4 systems designed to create an open platform for Tier-1 suppliers and vehicle manufacturers.

Veoneer’s software stacks are automotive grade solutions designed to meet the requirements of manufacturers, regulators and rating agencies globally. It has received top performance ratings and enabled automakers to achieve five star safety ratings for European New Car Assessment Program (Euro NCAP) in 2018 and 2020.

The companies plan to launch an automotive grade, functional safety compliant and optimised platform which will include a range of optimised NCAP features and up to hands-free driving on highways and slow-moving traffic with over the air updates.

The software stack will be developed in a dedicated organisation within Veoneer.

Designed to address the growing complexities associated with developing ADAS, including safety compliance, the integrated software and SoC platform targets the automotive ecosystem with advanced and power-efficient compute, connectivity and cloud service capabilities across all vehicle tiers with Veoneer’s fifth generation perception software and driving policy software and the Snapdragon Ride portfolio.

Qualcomm Technologies intends to make this integrated SoC and software stack platform available to global manufacturers and Tier 1 suppliers.

Veoneer will serve as a Tier 1 system integrator for the software and SoC platform and will continue to develop ADAS and collaborative driving products and systems.

The company will develop an open and programmable platform to offer more customisation. The companies expect the integrated platform to be available through automotive Tier 1 suppliers or directly to OEMs for 2024 vehicle production.

The Qualcomm Snapdragon Ride platform was introduced earlier this year. It is based on the Snapdragon family of automotive SoC and accelerator products, which are built on scalable and modular heterogenous, multi-core CPUs. This basis makes it suitable for planning and decision making, energy efficient AI and computer vision (CV) engines, graphics processor units (GPUs) for visualisation, image signal processors for camera sensors, and dedicated safety and security subsystems.

The integrated platform with Veoneer’s software stack will be built on the scalable Snapdragon Ride roadmap, offering industry leading scalability from L1 ADAS to L4 autonomous driving SoC and accelerator products.
