Smart manufacturing specialist, Foxconn, video and imaging SoC company, Socionext and artificial intelligence (AI) chip manufacturer, Hailo, have partnered to introduce Boxiedge AI edge computing for energy-efficient, standalone, AI inference nodes.

Foxconn’s high-density, fanless Boxiedge edge computer is combined with Socionext’s SynQuacer SC2A11, high-efficiency parallel processor and the Hailo-8 deep learning processor. According to the trio, the combination provides market-leading energy efficiency for standalone AI inference nodes, in smart cities, smart medical, smart retail applications and the industrial IoT.

It is designed to address the need for cost-effective multi-processing capabilities required in video analytics, image classifications and object segmentation in these compute-intensive applications. The robust, Boxiedge AI edge computing product is capable of processing and analysing over 20 streaming camera input feeds in real-time, at the edge. The result is a high-density, low-power, local video management system (VMS) server, ensuring top performance for video analytics and privacy, including image classification, detection, pose estimation, and various other AI-powered applications – all in real time.

Hailo’s specialised Hailo-8 deep learning processor features up to 26 Tera operations per second (TOPS). Its architecture enables edge devices to run sophisticated deep learning applications that could previously only run on the cloud. Its structure translates into higher performance, lower power and minimal latency, enabling enhanced privacy and better reliability for smart devices operating at the edge, said the company.

Gene Liu, VP of semiconductor sub group at Foxconn Technology, said: “We recognise the great potential in adopting AI solutions for a multitude of applications, such as tumor detection and robotic navigation. . . our edge computing solution combined with Hailo’s deep learning processor will create even better energy efficiency for standalone AI inference nodes to positively impact rapidly evolving [market] sectors.”

“We are very pleased with this joint effort by the companies, and to officially announce our strategic partnership with Hailo,” said Noriaki Kubo, executive VP at Socionext. “This collaboration will lead to more innovative solutions that specifically address the growing demand from our AI customers in multiple sectors. We are confident that this product will enable endpoint devices to operate with better performance, lower power, more flexibility, and minimal latency.”

The next generation of the Boxiedge AI computing is equipped with applications for a broader market relying on low latency, a high data rate, high reliability and quick processing at the edge. Smart retail and smart cities, for instance, require hundreds of cameras – either in-store or in traffic monitoring – to generate video streams that need to be processed locally, quickly, and efficiently with minimal latency.

Similarly, for industrial IoT, data acquiring, processing, inferencing, and presenting on the production floor rather than in the cloud translates into significant cost savings along with more efficient processing for tasks such as inspection and quality assurance.

Renesas extends Bluetooth 5.0 security to RA 32-bit microcontrollers

Bluetooth 5.0 connectivity has been extended to the RA family of 32-bit microcontrollers by Renesas Electronics, with the introduction of the RA4W1, with an Arm Cortex-M core.

In addition to the 8MHz, 32-bit Arm Cortex-M4 core, it has an integrated Bluetooth 5.0 low energy radio and is delivered in a 56-pin QFN package. The RA4W1 microcontroller and Flexible Software Package (FSP) enables engineers to immediately begin development with Arm ecosystem software and hardware building blocks, says Renesas. FSP features FreeRTOS and middleware for device-to-cloud development. Renesas also points out that options can be replaced and expanded with any other RTOS or middleware.

The RA4W1 microcontroller allows embedded designers to develop safe and secure IoT endpoint devices for industry 4.0, building automation, metering, healthcare, consumer wearable and home appliance applications. It is intended for engineers developing IoT edge devices for wireless sensor networks, IoT hubs, an add-on to gateways and an aggregator to IoT cloud applications.

Sakae Ito, vice president of IoT Platform Business Division at Renesas, said that customers can use the on-chip features, such as Renesas’ Secure Crypto Engine. This feature supports customers with symmetric encryption and decryption, hash functions, true random number generation (TRNG), and advanced key handling with key generation and microcontroller-unique key wrapping for strong key management for IoT security. It also has what is claimed to be best-in-class output power consumption and sensitivity for secure, longer range applications.

The Arm Cortex M4 core and Bluetooth 5.0 core are housed in a 7.0 x 7.0mm 56-pin QFN. The single-chip RA4W1 48MHz microcontroller features 512 kbyte flash memory, 96 kbyte SRAM and connectivity such as USB, CAN and Renesas’ HMI capacitive touch technology.

Bluetooth 5.0 support includes 2 Mbits per second data throughput, all advertising extension functions with maximum advertising length (1,650 byte), periodic advertisements and channel selection algorithm #2 for applications requiring large amounts of traffic. The RA4W1 also offers low peak power consumption at 3.3mA during receiving and 4.5mA (at 0dBm) while transmitting. Renesas claims its sensitivity of -105dBm in 125 kbits per second mode is an industry best and is achieved without additional loss from external components.

Renesas provides several API functions that conform to all standard profiles, including a heart rate profile (HRP), an environment sensing profile (ESP) and an automation I/O profile (AIOP), to allow users to quickly start and speed up prototype development and evaluation.

Renesas’ Smart Configurator GUI generates Bluetooth code and microcontroller peripheral function driver code as well as pin settings for the e2 Studio integrated development environment (IDE). The Renesas QE tool for Bluetooth LE generates programs for custom profiles and embeds them in user application programs to support application program development. The Bluetooth Trial Tool Suite GUI allows users to perform initial wireless characteristics evaluations and Bluetooth functional verification. Users can typically have the RA4W1 evaluation board up and running with the downloadable smartphone applications demo in less than 30 minutes, says Renesas.

Integrating a high-precision, low-speed on-chip oscillator, an RF oscillator adjustment circuit and on-chip matching circuit for easy antenna connection reduces both bills of materials costs and circuit board area.

Bluetooth beacons help hospitals track equipment

Keeping track – in real time – of medical equipment assets such as ventilators and defibrillators has never been more vital. Sixgill has developed Sense Hospital Asset Orchestration to track portable equipment to save time when it needs to be delivered quickly. The Bluetooth Low Energy (LE) AC plug-in wireless hub and ‘stick on’ beacon asset tracking solution uses Nordic Semiconductor’s nRF52832 SoC.

It tracks the location of assets within rooms and hallways using a technique based on Bluetooth LE beacon received signal strength indication (RSSI). All collated data is made available to hospital staff on a Sixgill-developed, cloud-based control panel. This graphically displays all tracked assets with colour-coded circles to show various status alerts (e.g. red to show assets that have been recently moved).

Sixgill says the rapid installation speed of its tracker is due to the simplicity of the drill- and screw-free design. This comprises two parts. First is AC plug-in wireless hubs based on a pass-through socket design. This is plugged into a single mains power socket in each room or hallway where asset tracking is required. Each one can cover a space of around 7.6 x 7.6m or 58m2 (25 x 25 feet or 625 feet2). The mains plugs have a Nordic nRF52832 installed to look and listen for Bluetooth LE beacons, and Wi-Fi to communicate to the cloud.

The stick-on Bluetooth LE beacons are attached to any asset the hospital would like to track. The nRF52832 SoC’s low power consumption means each beacon does not need to be recharged once installed. Its battery will last three to five years depending on the duty cycle. The Sense solution is scalable to support an unlimited number of Bluetooth LE beacons.

“Now a hospital is able to capture all asset information, transmit data and alerts as needed to appropriate staff, and reduce if not eliminate errors and delays when delivering critical assets to where they are needed,” says Joan Silver, VP of product marketing at Sixgill. “By collecting meaningful data and analysing it over time hospitals are also able to gain insights that optimise their operational and planning efficiencies. Our solution even supports [artificial intelligence] AI and machine learning to continuously improve a hospital’s understanding of its portable asset utilisation patterns to enable prediction of needs during both normal operations and emergency surges.

“Wireless ultra-low power consumption removes customer objections to extensive new wiring or incessant battery maintenance,” added Silver.

Microcontroller enables real-time control for smart cities, says Microchip

Core independent peripherals, advanced analogue and on-chip communications are integrated in the latest AVR microcontrollers from Microchip. The higher-performance microcontrollers are required for better real-time control as well as to enable enhanced human machine interface (HMI) applications, explains Microchip. The AVR DA family of microcontrollers is the company’s first functional safety-ready AVR microcontroller family with Peripheral Touch Controller (PTC).

The family of microcontrollers meets new demand across multiple industries with advanced analogue and core independent peripherals and more capacitive touch channels over existing devices, said Greg Robinson, associate vice president of marketing, 8-bit microcontroller business unit. Target applications are the connected home security, building automation and sensor systems to automotive and industrial automation.

Microchip’s Functional Safety Ready designation covers devices that incorporate the latest safety features and are supported by safety manuals, failure modes, effects, and diagnostic analysis (FMEDA) reports, and in some cases, diagnostic software. This reduces the time and cost of certifying safety end applications. The AVR DA microcontroller family includes several integrated safety functions to ensure robust operation to ensure a sufficient supply voltage such as power-on reset, brown-out detector and voltage-level monitor. The cyclic redundancy check (CRC) scan ensures the application code in the flash memory is valid. By ensuring code integrity, unintended and potentially unsafe behaviour of the application can be avoided.

The AVR DA family of microcontrollers enable CPU speeds of 24 MHz over the full supply voltage range, memory density of up to 128 kbyte flash, 16 kbyte SRAM and 512 bytes of EEPROM, 12-bit differential ADC, 10-bit DAC, analogue comparators and zero cross detectors.

The PTC enables capacitive touch interface designs supporting buttons, sliders, wheels, touchpads, smaller touch screens as well as gesture controls used in a wide range of consumer and industrial products and vehicles. The AVR DA family supports up to 46 self-capacitance and 529 mutual capacitive touch channels and features the latest generation PTC with Driven Shield+ and boost mode technologies to enhance noise immunity, water tolerance, touch sensitivity and response time, says Microchip.

For embedded real-time control systems, the integrated event system enables inter-peripheral communication without involving the CPU. Events are latency-free and never lost, for predictable, reliable and safe designs. By reducing the time the CPU needs be active, the overall power consumption of the application is reduced.

The configurable custom logic peripheral enables the set-up of logical functions internally, eliminating the need for external components, reducing board space and bill of material costs. With the advanced analogue features like the 12-bit differential ADC, the AVR DA family of microcontrollers can measure small amplitude signals in noisy environments, making them well suited for sensor node applications in harsh environments.

According to Microchip, the high memory density and SRAM-to-flash ratio make the microcontrollers attractive for both wireless and wired connected sensors nodes, as well as other stack-intensive applications.

Software support includes Microchip’s MPLAB X, MPLAB Xpress and Atmel Studio, code configuration tools including MCC and START, and compilers including GCC, XC8 and the IAR Embedded Workbench. A functional safety certified version of the XC8 compiler is available via Microchip’s Functional Safety Ready program. Hardware support is included in debuggers/programmers including MPLAB PICkit 4, MPLAB SNAP, Atmel ICE and the AVR128DA48 Curiosity Nano evaluation kit.

The AVR DA family of microcontrollers is available in volume production now.
