First Commercial iSIM with Remote SIM Provisioning: G+D and Sony Semiconductor Israel are proud to announce the first-ever commercial iSIM solution that supports remote SIM provisioning, a landmark that is set to make IoT connectivity more seamless and cost-effective.
Optimized Efficiency & Security: The iSIM-enabled ALT1350 chipset by Sony incorporates G+D’s secure SIM operating system in a tamper-resistant element, providing unparalleled security features and operational efficiency.
Flexible Network Selection & Global Scaling: This pioneering iSIM technology enables high flexibility in choosing cellular networks and simplifies the global scaling of deployments, addressing the varying needs of IoT devices across diverse sectors.
The integrated SIM (iSIM) is an important evolutionary step in SIM technology, empowering simple and cost-efficient connection, deployment, and go-to-market for Internet of Things (IoT) devices. Giesecke+Devrient (G+D) is playing a key role in shaping this development and, together with Sony Semiconductor Israel (Sony), is launching the first commercial iSIM solution that supports remote SIM provisioning.
The iSIM, or integrated Universal Integrated Circuit Card (iUICC), has the potential to revolutionize IoT and makes devices more flexible and efficient. It is cost-optimized, smaller, more adaptable, and sustainable than previous generations of SIMs and will complement established solutions such as the pluggable SIM and eSIM. As the world’s first providers, G+D and Sony are now taking iSIM development a step further by introducing a secure solution that is specifically designed for remote SIM provisioning (RSP), enabling seamless over-the-air activation and management of SIM profiles. This allows for high flexibility to choose the preferred cellular network throughout the long lifespan of an IoT device, while also offering the most cost-effective solution over its lifetime, according to a recent whitepaper from Transforma Insights. The capability to set profiles depending on the device’s location simplifies the global scaling of deployments. Additionally, RSP helps streamline production, storage, and logistics processes, to enhance operational efficiency.
The new solution is based on the iSIM-enabled ALT1350 chipset by Sony, which now supports standardized and future-proof RSP. G+D’s secure SIM operating system (OS) is stored in a tamper-resistant element (TRE) within a system-on-a-chip (SoC), unlike insertable SIM cards or soldered eSIMs. It acts as an isolated hardware component that is combined with a baseband chipset to form a single connectivity module.
The iSIM offers numerous advantages: Less hardware comes with a minimal footprint and enables the production of small, lightweight, and therefore cost-effective devices, and the optimized energy consumption increases device efficiency. High security is provided by the isolated hardware in combination with G+D’s secure and certified SIM OS. Production and warehousing processes can be optimized because there is no need to solder different hardware components or plug SIM cards into the device. Finally, iSIMs also support higher sustainability requirements, with the absence of slots, additional housings, or plastic.
Due to its low power consumption and small size, the iSIM is an ideal choice for battery-constrained IoT devices operating in low-power wide-area networks (LPWANs) through Narrowband IoT (NB-IoT) or Long Term Evolution for Machines (LTE-M) technologies. Wearables are also among the potential areas of application. Typical use cases can be found in market segments such as smart metering, agtech, smart health, tracking and tracing or the entire spectrum of massive IoT.
With the AirOn360® central SIM management solution, G+D provides a comprehensive service for over-the-air administration of iSIMs. It supports both remote SIM provisioning of network operator-specific data and update management. The solution complies with GSMA RSP specifications for consumer, M2M, and IoT applications and helps Original Equipment Manufacturers (OEMs) or device owners manage the iSIM lifecycle efficiently and securely. RSP in accordance with the new GSMA SGP.32 standard for M2M/IoT use cases empowers IoT device operators with maximum flexibility in their choice of mobile network operators. This allows them to choose the optimal provider in terms of cost, service quality or network coverage, for example.
“As market leader in eSIM, G+D has been investing in the research and development of iSIM technology for a long time. Together with industry partners, we want to accelerate SIM innovation. A good example for this is our cooperation with Sony, under which we are now announcing the industry’s first commercial iSIM with remote SIM provisioning. This pioneering achievement empowers our customers to unlock the full potential of the IoT with flexible and cost-optimized connectivity. We are convinced that this will be another important milestone in the iSIM evolution,” explains Bernd Müller, Head of Technology and Strategy in the connectivity & IoT business at G+D.
“This solution marks another joint success between Sony and G+D. The iSIM is poised to reshape the future of IoT in which everything is connected,” added Dima Feldman, VP Product Management & Marketing at Sony Semiconductor Israel. “Our ALT1350 baseband chipset combined with G+D’s SIM operating system and management solution, has led to a powerful, simple, and secure IoT connectivity management system that will drive the market forward.”

ARIES Embedded, a specialist in embedded services and products, presents the new SMARC®-compliant system-on-modules (SoM) MRZG2LS and MRZV2LS. The SoMs are based on the Renesas RZ family architecture and provide high performance for embedded systems. The RZ/G2L microprocessor from Renesas includes a Dual Cortex®-A55 (1.2 GHz) CPU, 16-bit DDR3L/DDR4 interface, 3D graphics engine with Arm Mali-G31 and video codec (H.264). “While the MRZG2LS SoM integrates the single/dual Cortex®-A55/Cortex®-M33, the MRZV2LS is equipped with a Cortex®-A55 (1.2GHz) CPU and built-in AI accelerator ‘DRP-AI’ for vision applications, which is Renesas’ original technology,” explained Andreas Widder, Managing Director of ARIES Embedded. “Our new SoMs are ideal for applications such as entry-class industrial human-machine interfaces (HMIs), embedded vision, edge artificial intelligence (edge-AI), real-time control, industrial ethernet connectivity, and embedded devices with video capabilities.”
With the MRZG2LS and MRZV2LS, ARIES Embedded provides their first SoMs compliant with the SMARC® 2.1 (Smart Mobility Architecture) standard by SGET (Standardization Group for Embedded Technologies e. V.). This standard defines a versatile small form factor computer module targeting applications that require low power, low costs, and high performance.
Artificial Intelligence Acceleration
The AI accelerator “DRP-AI” from Renesas is configured with DRP and AI-MAC. DRP-AI’s excellent power efficiency eliminates the need for heat dissipation measures such as heat sinks or cooling fans. AI can be implemented cost efficiently, not only in consumer electronics and industrial equipment but also in a wide range of applications such as point-of-sale (POS) terminals for retail. Also, the DRP-AI provides both real-time AI inference and image processing functions with the capabilities essential for camera support, such as color correction and noise reduction. This enables customers to implement AI-based vision applications without requiring an external image signal processor (ISP).
High-Performance Embedded Systems
The new SoMs MRZG2LS and MRZV2LS offer a manifold feature set around the single or dual Cortex-A55, up to 1 GHz, and the Cortex-M33.

The art of wine appreciation and the joy of opening a bottle have long been intertwined with using a corkscrew. Over the years, advancements in technology have revolutionized this process, bringing about the advent of electric corkscrews. These innovative devices, powered by a motor, have streamlined the wine-opening experience, making it effortless, efficient, and enjoyable for wine enthusiasts and professionals alike. This article guides how to use the Renesas’ SLG47105 HVPAK so as to implement an electric corkscrew. However, you may download our free GreenPAK Designer software to open the .gp file and view the proposed circuit design. Use the GreenPAK development tools to freeze the design into your own customized IC in a matter of minutes.
Brushed DC motors are used to implement the design. The motor driver plays a crucial role in them, providing the necessary torque, speed, and control required to perform the delicate task of removing the cork from the bottle.
The Renesas’ SLG47105 HVPAK combines mixed-signal logic and high-drive H-/Half-Bridges and proves to be an ideal choice for implementing the functionality of an electric corkscrew. Figure 2 illustrates a general schematic of the device based on the HVPAK.
Figure 2. General Schematic of Electric Corkscrew Based on the SLG47105 HVPAK
GreenPAK Design
Figure 3 shows an internal design of the electric corkscrew in the GreenPAK Designer software.
Figure 3. Electric Corkscrew GreenPAK Designer Schematic
The main role in driving the motor is performed by high-drive pins 7, 8, 9, and 10 along with their corresponding control macrocells HV OUT Ctrl0 and HV Out Ctrl1. To increase the current rating, users have the option to connect the outputs in parallel, which was implemented in the corkscrew circuit.
Because the corkscrew needs to rotate in both directions, the macrocells HV OUT Ctrl0 and HV Out Ctrl1 are configured in Full-Bridge mode. By supplying a HIGH level signal from the POR (Power-On Reset) to the Decay inputs of HV OUT Ctrl0 and HV Out Ctrl1, a Slow decay mode is activated. This mode allows for a gradual reduction in an inductive current, resulting in a quick halt of the motor’s movement.
Current Regulation
In this design, a current control was used. The current control circuit is provided to regulate the system in the event of an overcurrent condition, such as an abnormal mechanical load on a DC motor. The current is sensed by an external sense resistor connected to the SENSE_A and SENSE_B pins. The resistor value is calculated using the formula:
The current sense comparator (CCMP0) is used to convert the sense resistor current into a logic level, thus limiting the output current. In this case, Rsense was chosen to be equal to 0.11 Ω, Vref was set to 998 mV, and the gain was set to 4, resulting in a limiting current of 2.2 A. This current comparator signal is utilized by the PWM Chopper to chop the PWM duty cycle. By using the current comparator with the PWM block, the output current can be dynamically adjusted. The operational principle of the PWM chopper is illustrated in Figure 4.
Figure 4. PWM Chopper Circuit Block Diagram
A delay allows us to ignore the Current Comparator signal during the Blanking time, which occurs during the motor start period. Any active signal from the Current CMP after the Blanking time causes the PWM Duty Cycle to be chopped to the end of the current period. Figure 5 demonstrates the PWM chopping process in the electric corkscrew.
Figure 5. PWM Chopper Working Waveform
Voltage Regulation
Because the device is powered by a lithium-ion battery, the PWM voltage regulation is useful for this design. It allows us to maintain a constant motor speed with a changeable power supply level. When the VDD is decreasing (the battery discharging), it becomes possible to increase the PWM duty cycle.
For the voltage regulation, the Differential Amplifier with Integrator and Analog Comparator macrocell is used. This macrocell monitors the voltage difference between HV_GPO0_HD and HV_GPO1_HD pins of the Full Bridge and integrates it to get an average voltage value. If the average output voltage is lower than Vref, the duty cycle of the PWM output needs to increase; if the average output value is higher than Vref, the duty cycle needs to decrease; when the average output value is equal to the comparator threshold, the PWM duty cycle is kept by EQUAL output. Figure 6, Figure 7, and Figure 8 show the voltage regulation process in the electric corkscrew.
Figure 6. PWM Chopper OUT at VDD = 4.2 V (Duty Cycle = 76 %).Figure 7. PWM Chopper OUT at VDD = 3.7 V (Duty Cycle = 86 %)Figure 8. PWM Chopper OUT at VDD = 3.3 V (Duty Cycle = 97 %)
The integrator reference voltage was set to 864 mV, resulting in a threshold of 3.456 V. This threshold value guarantees a constant voltage of 3 V across the motor winding, regardless of the battery voltage.
Motor Control Logic
When the user presses the “Uncork” button, a short LOW level pulse is generated at the output of Pin 16. To eliminate switch bouncing, a Delay macrocell DLY2 is used. In sleep mode, the output of the 3-bit LUT9 remains LOW. However, when any of the following events occurs: the “Uncork” button is pressed, the cork activates the microswitch, or the timer is triggered – the output transitions to a HIGH level. On the rising edge of this pulse, DFF8 changes its state to the opposite, resulting in a LOW level output. Subsequently, the output of the 4-bit LUT1 goes HIGH. This signal is fed to the Edge Detector macrocell that works as both edges delayed inverter. It activates the HV OUT control blocks and auxiliary macrocells, bringing them out of sleep mode and initiating the clockwise rotation of the motor. The 4 ms DLY3 is necessary to ensure that the comparators are powered up before the 3-bit LUT9 output signal reaches the CLK input of the DFF8.
Additionally, the rising edge of the signal from the output of 4-bit LUT1 is delayed by DLY0 for 30 seconds. If the corkscrew is not turned off within 30 seconds, this delayed rising edge signal reaches the input of the 3-bit LUT9, causing its output to go HIGH. This change in state forces DFF8 to switch its state, and the output of the 4-bit LUT1 goes LOW, resulting in the motor ceasing its operation. A similar sequence of events occurs when the cork is unscrewed to a sufficient extent to activate the microswitch (signaling the end of uncorking), which connects Pin 3 to GND. The 30-second timer function ensures that the motor shuts off and the corkscrew enters sleep mode for both the uncorking and cork removal modes. This shutdown function enables power conservation and prevents overheating.
When the user presses the “Remove Cork” button, DFF7 changes its state to the opposite, resulting in a LOW level output. Subsequently, the output of the 4-bit LUT1 goes HIGH, initiating the motor’s counterclockwise rotation. Similarly, to eliminate this switch bouncing, a Delay macrocell DLY1 is used. Furthermore, to eliminate microswitch bouncing, a Pipe Delay is employed.
P DLY macrocell that works as a delayed rising edge detector, paired with DFF0, is designed to detect which button was pressed. The signal from the output of DFF0 is fed to the PH inputs of the HV OUT Control blocks, determining the direction of motor rotation based on the button pressed. Specifically, if the output of DFF0 is LOW, the motor rotates clockwise, and if it is HIGH, the motor rotates counterclockwise.
Depending on which button is pressed and if the corkscrew is in working mode, the 2-bit LUT2 and 2-bit LUT3 generate a HIGH level signal for one of the LEDs. The red LED illuminates when the output of the 2-bit LUT2 is HIGH (indicating the active uncorking mode), while the blue LED lights up when the output of the 2-bit LUT3 is HIGH (indicating the active cork removal mode).
Additionally, the corkscrew can be turned off by pressing either of two buttons while it is in working mode.
The 3-bit LUT0 enables DFF7 and DFF8 only if the following conditions are met: no charger is connected, the battery voltage is above 3 V, and the POR output signal is HIGH. The ACMP1 measures the battery level, while paneACMP0 detects the presence of a connected charger.
To ensure low energy consumption in sleep mode, the Differential Amplifier with Integrator and Analog Comparator macrocell, along with analog comparators ACMP0H and ACMP1H, are designed to exit sleep mode upon pressing any button. The signals from these buttons first pass through the 2-bit LUT1, which outputs a pulse for any change in its inputs. The DFF9 changes its state in response to this pulse. Subsequently, the signal is inverted and supplied to the power inputs of the comparators and the amplifier.
The 3-bit LUT3 enables the operation of HV OUT Control blocks if signals FAULT A and FAULT B are LOW (indicating no fault events).
Conclusion
This article explores the utilization of the SLG47105 HVPAK in a corkscrew implementation. This HVPAK is a versatile device that offers a wide range of mixed-signal functionalities combined with high-voltage capabilities, all packed into a compact and thermally efficient integrated circuit. With its abundance of digital and analog blocks, it can replace multiple ICs required for the corkscrew’s operation, including the motor driver, logic components, and a voltage monitor. Additionally, it provides features such as voltage and current control, along with advanced protection mechanisms against abnormal situations. The device is cost-effective and energy-efficient, making it an excellent choice.

Compared to Arduino PLC IDE where all the programming languages defined by the IEC 61131-3 standard are licensed and you have to pay almost $18 for their Potenta Machine control PLC key, this PLC IDE is completely open source and does not require you to pay license fee for any of the programming languages that it supports. You are only charged for buying copies of the standard, as required by IEC.
OpenPLC Runtime is claimed to be able to run from the tiniest of all microcontrollers to real PLC and then to powerful cloud servers. It is fully supported on several development boards and actual PLC hardware, including:
ESP32 / ESP8266
Arduino Nano / Uno / Micro / Leonardo
Arduino Mega/Due
Arduino Mkr / Zero / WiFi
Arduino Nano Every/IoT/BLE
Arduino Pro
Productivity Open P1AM
PiXtend
Neuron PLC
Controllino Maxi/Automation/Mega/Mini
UniPi industrial platform
Ideally, OpenPLC finds its use mostly in IoT, industrial automation, and control systems but its open-source nature has made it possible for many researchers to also leverage it as a framework for industrial cybersecurity research.
For support and inquiries, the OpenPLC developer, Thiago Alves, encourages users to engage their vibrant community forum which currently has over 3,000 members from everywhere in the globe and over 50,000 page views per month. The forum is fully supportive; you can see all the new stuff coming to the OpenPLC project, drop bug reports from the Editor, or just get engaged in general discussions that relate to the OpenPLC project. You will also have access to learning materials where you can learn about PLC programming, HDMI development, etc. Alves also revealed that they are currently working on bringing training to the community encompassing all major topics, from basic ladder logic programming to advanced cybersecurity.
Other useful details on the OpenPLC including source codes for the Runtime and Editor can be found on the developer’s GitHub repository while the website has links to download the OpenPLC Editor for Windows, Linux and macOS.
