To help device manufacturers to develop secure IoT products, Microchip Technology introduces the PIC-IoT WG development board for Cloud IoT Core. PIC microcontrollers are used in a wide variety of products, from coffee makers to thermostats and irrigation systems yet as developers migrate next-generation PIC microcontroller-based applications to the cloud, they have to overcome complexities associated with communications protocols, security and hardware compatibility. To accelerate the development of these applications, Microchip has announced an IoT rapid development board for Google Cloud IoT Core that combines a low-power PIC microcontroller, CryptoAuthentication secure element IC and fully certified Wi-Fi network controller. According to Microchip, this provides a simple way to connect and secure PIC microcontroller-based applications, removing the added time, cost and security vulnerabilities that come with large software frameworks and real time operating systems (RTOS). Once connected, Google Cloud IoT Core provides powerful data and analytics to help designers make better, smarter products, explains Microchip.

Microchip Technology has an extended partnership with Google Cloud, which means that the PIC-IoT WG development board enables PIC microcontroller designers to easily add cloud connectivity to next generation products using a free online portal at www.PIC-IoT.com. Once connected, developers can use Microchip’s MPLAB Code Configurator (MCC) development tool to develop, debug and customise an application. The board combines smart, connected and secure devices to enable designers to create connected applications. It includes the eXtreme low-power PIC microcontroller with integrated core independent peripherals. Suitable for battery-operated, real-time sensing and control applications, the PIC24FJ128GA705 microcontroller employs the PIC architecture with added memory and advanced analogue integration explains Microchip. It is supported by the latest Core Independent Peripherals (CIPs) designed to handle complex applications with less code and decreased power consumption.

There are also secure element to protect the root of trust in hardware. The ATECC608A CryptoAuthentication device provides a trusted and protected identity for each device that can be securely authenticated. It is supplied pre-registered on Google Cloud IoT Core. For Wi-Fi connectivity to Google Cloud, the ATWINC1510 is an industrial-grade, fully certified IEEE 802.11 b/g/n IoT network controller that provides an easy connection to a microcontroller via an SPI, with the designer needing networking protocols expertise.

Google Cloud IoT Core provides a managed service that enables designers to easily and securely connect, manage and ingest data from devices at a global scale. The platform collects, processes and analyses data in real time to enable designers to improve operational efficiency in embedded designs.

Ethernet PHYs optimise network performance

Fri, Feb 22, 2019

Two Ethernet physical layer (PHY) transceivers have been introduced by Texas Instruments. They are designed to offer more connectivity options for designers of both space-constrained applications and time-sensitive networks (TSNs).

The DP83825I low-power 10-/100-Mbits per seocnd Ethernet PHY has a 44 per cent smaller package size than competing devices, claims Texas Instruments and provides a 150m cable reach. The DP83869HM is the industry’s only gigabit Ethernet PHY that supports copper and fibre media, and offers high -temperature operation up to 125 degrees C, which enables engineers to leverage the speed and reliability of Gigabit Ethernet connectivity in harsh environments.

The small package, low power consumption and long cable reach of the DP83825I enable designers to reduce the size and cost of compact IP network camera, lighting, electronic point-of-sale and other space-constrained applications without sacrificing network reach, explains Texas Instruments. The high operating temperature of the DP83869HM, as well as its electrostatic discharge (ESD) immunity and support for media conversion, are claimed to help increase performance and design flexibility in factory automation, motor drive and grid infrastructure equipment designs.

Network reach can be expanded while system size and cost can be reduced, with the DP83825I. This is claimed to be the industry’s smallest Ethernet PHY, in a 3.0 x 3.0mm QFN 24-pin package. It also has a long cable reach and helps designers shrink system designs while increasing the physical span of networks, says Texas Instruments. The device’s extended cable reach eliminates the need for Ethernet repeaters, which further reduces operating costs.

The DP83825I reduces thermal loading and power demands for Ethernet connectivity and enables the allocation of power to other critical components within a system by consuming less than 125mW. The device also includes power-saving features such as energy-efficient Ethernet, wake-on-LAN and media access control isolation.

The DP83869HM is claimed to have the industry’s widest temperature range and high ESD immunity. Operating temperature is -40 to +125 degrees C for Gigabit fibre operation and ESD immunity exceeds the 8kV International Electrotechnical Commission 61000-4-2 standard. The DP83869HM helps improve Ethernet system reliability in high-temperature and static-prone industrial environments such as factory floors.

It supports 1000Base-X and 100Base-FX Ethernet protocols and conversion between copper and fibre Ethernet standards, to extend long-distance networks. There is also TSN support through low latency (less than 390 nano seconds total) for both 1000Base-T and 100Base-TX standards.

Evaluation models for both PHYs are available.

Microprocessor adds Linux distribution to accelerate IoT innovation

Thu, Feb 21, 2019

As part of its commitment to 10-year industrial-grade supply, STMicroelectronics has introduced the STM32MP1 microprocessor series with Linux distribution. According to STMicro, the multi-core STM32MP1 architecture is particularly suited to open-source software-based applications in real-time and power-constrained sub-systems

It also reduces development time using OpenSTLinux mainlined, open-source Linux distribution and the established STM32Cube ecosystem

STMicro has applied its Arm Cortex expertise to expand the capabilities of its STM32 microcontroller to applications which require more performance, resources and large open-source software. The STM32MP1 multi-core microprocessor series has compute and graphics support combined with power-efficient real-time control to support developers of industrial, consumer, smart home, health and wellness applications.

The STM32MP1 series microprocessor uses the STM32-family ecosystem from ST and its partners, including tools and technical support.

“The STM32MP1 brings the strength of the STM32 experience to applications that need MPU compute and graphics support, combined with power efficient real-time control and high feature integration,” said Ricardo De Sa Earp, general manager of STMicroelectronics’ microcontroller division. “Our commitment to consolidating open-source Linux software and microcontroller development support, combined with the longevity that consumer-oriented alternatives cannot equal, establish solid confidence in STM32MP1 for embedded MPU projects,” he adds.

Designers can use the STM32MP1 microprocessor series to develop a range of applications using the STM32 heterogeneous architecture that combines Arm Cortex-A and Cortex-M cores. The architecture performs fast processing and real-time tasks on a single chip, always achieving the greatest power efficiency, says STMicro. For example, by stopping Cortex-A7 execution and running only from the more efficient Cortex-M4, power can typically be reduced to 25 per cent. From this mode, going to standby further cuts power by 2.5k times – while still supporting the resumption of Linux execution in one to three seconds, depending on the application.

The STM32MP1 embeds a 3D graphics processor unit (GPU) to support human machine interface (HMI) displays. It also supports a wide range of external DDR SDRAM and flash memories. The large set of peripherals can be seamlessly allocated either to Cortex-A / Linux or Cortex-M / real-time activities. The STM32MP1 series is available in a range of BGA packages to minimise PCB cost and use the smallest board space.

The release of OpenSTLinux distribution has already been reviewed and accepted by the Linux community: Linux Foundation, Yocto project and Linaro. The distribution contains all the essential building blocks for running software on the application-processor cores.

Enhanced STM32Cube tools, upgraded from the STM32Cube package for Cortex-M microcontrollers, accelerate microprocessor development using Arm Cortex-A-core MPUs.

Two evaluation boards (STM32MP157A-EV1 and STM32MP157C-EV1) and two Discovery kits (STM32MP157A-DK1 and STM32MP157C-DK2) will be available through distribution channels in April.
