Microchip introduces ECC608 TrustMANAGER with Kudelski IoT keySTREAM

Wed, Apr 03, 2024

As the world comes to rely on interconnected IoT systems—for everything from household items like smart thermostats, virtual assistant technology and digital door locks to medical and industrial applications—the need for reliable cybersecurity on embedded systems has never been greater. To increase security on IoT products and facilitate easier setup and management, Microchip has added the ECC608 TrustMANAGER with Kudelski IoT keySTREAM, Software as a Service (SaaS) to its Trust Platform portfolio of devices, services and tools.

With security credentials managed and updated in the field via keySTREAM—instead of being limited to a static certificate chain implemented during manufacturing—the ECC608 TrustMANAGER allows custom cryptographic credentials to be accurately provisioned at the end point without requiring supply chain customisation and can be managed by the end user. keySTREAM offers a device-to-cloud solution for securing key assets end-to-end in an IoT ecosystem throughout a product’s lifecycle.

The ECC608 TrustMANAGER relies on a secure authentication IC that is designed to store and protect cryptographic keys and certificates, which are then managed by the keySTREAM SaaS. The combined silicon component and key management SaaS allow the user to set up a self-serve root Certificate Authority (root CA), and the associated public key infrastructure (PKI) secured by Kudelski IoT, to create and manage a dynamic certificate chain and provision devices in the field the first time they are connected. Once claimed in the SaaS account, the devices are automatically activated in the user’s keySTREAM service via in-field provisioning.

Security standards and upcoming regulations are increasingly requiring upgradability of security infrastructure for IoT devices. This is a difficult task with traditionally static IoT security implementations, which require physical upgrades like changing out the security ICs in each device to stay in compliance. With the ECC608 TrustMANAGER, the process is automated and highly scalable, allowing devices to be managed securely and efficiently throughout their lifecycle. It also enables easy device ownership management without needing to change hardware, as security keys are updated digitally from the cloud into the device. This approach streamlines the supply chain processes for distribution partners as well.

This type of in-field provisioning and device management meets IoT security standards and will be useful in device certificate updates needed to stay in compliance with evolving security requirements. The keySTREAM SaaS allows for ongoing updates of keys designed to prevent and protect against evolving threats and security requirements. In-field provisioning also removes the need for customisation for more efficient manufacturing.

Arrow Electronics launches intelligent vision ecosystem

Thu, Mar 28, 2024

Arrow Electronics is utilising the onsemi Imager Access System (IAS) module standard for developing intelligent vision solutions for use in robotics, machine vision, commercial cameras and other uses.

The solution reduces the design complexities that are common with designing a product that utilises image sensors. Part of that complexity is there is no standardisation of the hardware interfaces of the different technology blocks. This is where the onsemi IAS module standard comes in and is adopted throughout the ecosystem.

Working with Appletec, Arrow developed the newest IAS module, AP-VISION-AR0830-83 that utilises the latest generation of onsemi image sensors.

“The onsemi Hyperlux LP family of sensors set a new industry benchmark for ultra-low power sensor design. Combined with a small form factor, purpose-oriented features and best-in-class imaging, Hyperlux LP will be a fixture for smart home, office, and robotics for years to come,” said Stephen Harris, senior director of marketing for onsemi’s Industrial and Commercial Sensing Division. “onsemi is now able to bring the newest high-performance, feature-rich 4k sensor in the Hyperlux family, AR0830, to market with Arrow’s IAS module, allowing our customers to reduce camera development efforts significantly with best-in-class module design.”

This new module joins the existing portfolio of IAS modules offered by Arrow and Appletec.

Arrow worked with its company, eInfochips, and onsemi to develop drivers that enable the Appletec IAS modules to work with leading embedded processors.
“eInfochips has extensive experience in developing end-to-end vision solutions. This includes hardware design, image sensor integration and tuning, image processing, image driver development, low latency streaming and AI Inferencing on edge/cloud,” said Gaurav Patel, vice president and general manager of product engineering services for eInfochips. “Companies rely on eInfochips to deliver innovative vision solutions and accelerate and de-risk design cycles.”

Renesas introduces industry’s first general-purpose 32-bit RISC-V MCUs with internally developed CPU core

Wed, Mar 27, 2024

Renesas Electronics Corporation has announced the industry’s first general-purpose 32-bit RISC-V-based microcontrollers (MCUs) built with an internally developed CPU core. While many MCU providers have recently joined investment alliances to advance the development of RISC-V products, Renesas has already designed and tested a new RISC-V core independently, which is now implemented in a commercial product and available globally. The new, R9A02G021 group of MCUs provides embedded systems designers a clear path to developing a wide range of power-conscious, cost-sensitive applications based on the open-source instruction set architecture (ISA).

While most of today’s RISC-V solutions target specific applications, the R9A02G021 group MCUs are designed to serve multiple end markets, such as IoT sensors, consumer electronics, medical devices, small appliances and industrial systems. Similar to existing general-purpose MCUs, designers will have access to a full-scale development environment for the R9A02G021, provided by Renesas and its extensive network of toolchain partners. This will allow them to significantly reduce costs, engineering resources and development time.
The R9A02G021 RISC-V group offers ample performance with clock speeds up to 48MHz, while consuming extremely low power in standby at 0.3µA. It provides 128KB of fast flash memory, 16KB of SRAM memory and 4KB of flash memory for data storage. Designed to withstand harsh conditions, the MCUs can operate reliably at ambient temperatures ranging from -40 °C to 125 °C. The MCUs come with standard serial communications interfaces, as well as digital-to-analog converter (DAC) and analog-to-digital converter (ADC) functions to facilitate high-speed and secure connections with sensors, displays and other external modules. The wide 1.6V to 5.5V input voltage range enables low-voltage, low-current operation and allows noise immunity, making the R9A02G021 ideal for battery-powered devices.

The R9A02G021 RISC-V MCUs are fully supported by Renesas’ e² studio Integrated Development Environment (IDE), offered to customers at no cost. The comprehensive toolchain includes a code configurator, the LLVM compiler and a fast prototyping board (FPB). Complete development environments are also available from Renesas’ partners: IAR with its Embedded Workbench IDE and I-jet debug probe, and SEGGER with the Embedded Studio IDE, J-Link debug probes and Flasher production programmers.
