Microchip offers ISO 26262-compliant, AUTOSAR-ready DSCs

Tue, Jun 07, 2022

Digital signal controllers (DSCs) from Microchip Technology support AUTOSAR, OS, MCAL drivers and functional safety for automotive designs.

The addition to Microchip’s dsPIC33C DSCs portfolio, is the ISO 26262-compliant dsPIC33CK1024MP7xx family. The latest DSCs cover the large memory segment with 1Mbyte flash to enable applications running automotive software like AUTOSAR, OS, MCAL drivers, ISO 26262 functional safety diagnostics and security libraries. The dsPIC33 DSCs also includes a central processing unit (CPU) with deterministic response and specialised peripherals for general automotive, advanced sensing and control, digital power and motor control applications. 

The dsPIC33C DSCs enable accelerated development and a high level of system optimisation while reducing total system cost, claimed Microchip. They have been developed in response to OEMs experiencing increasing application complexity and the need for AUTOSAR, ISO 26262 functional safety-compliant and secure solutions for electric and autonomous vehicles. 

“The AUTOSAR-ready dsPIC33C DSCs enable designers to achieve a high level of system optimisation by implementing AUTOSAR-based applications, functional safety goals and security use cases in a single microcontroller while meeting robust automotive application requirements,” said Joe Thomsen, vice president of the MCU16 business unit at Microchip Technology.

By adopting AUTOSAR-ready devices, designers can improve risk and complexity management while decreasing development time through reusability. Customers who have previously designed bare metal or non-AUTOSAR automotive applications and are now adopting AUTOSAR can scale up by staying within the dsPIC33C DSC ecosystem, pointed out the company. The AUTOSAR ecosystem for the dsPIC33C DSCs includes MICROSAR Classic from Vector, KSAR OS from KPIT Technologies and ASPICE- and ASIL B-compliant MCAL drivers from Microchip.

Microchip has expanded its functional safety packages that include FMEDA reports, safety manuals and diagnostic libraries to cover the ISO 26262-compliant dsPIC33CK1024MP7xx DSCs. These AUTOSAR-ready dsPIC33C DSCs, used together with Microchip’s TA100 CryptoAutomotive security ICs, enable the implementation of robust security in automotive designs.

Software and tools from Microchip Technology include certified MPLAB XC16 compiler functional safety licenses, MPLAB X IDE (integrated development environment), MPLAB Code Configurator (MCC), programming and debugging tools for dsPIC33C DSCs, ISO 26262- and ASPICE-compliant MCAL drivers for dsPIC33C DSCs, ISO 26262 functional safety packages for dsPIC33C DSCs and software libraries and reference code for security use cases. Third-party software includes MICROSAR Classic from Vector and KSAR OS from KPIT Technologies. Third-party hardware tools include TRACE32 debugger from Lauterbach.

Charger IC is wireless power transfer-compatible

Tue, May 31, 2022

A multi-functional, compact charging IC for lithium-ion (Li-ion) batteries, the XC6810, supports wireless power transfer.

Available from Torex Semiconductor, the XC6810 series of charging ICs for Li-ion batteries are suitable for wearables, hearables or IoT devices. Functions include charge and discharge control as well as wireless power supply support. 

Charging current is 1.0 to approximately 25mA, making it suitable for small Li-ion batteries. The ICs can provide a wide charging range of 3.8 to 4.4V.The XC6810 series are equipped with shutdown function to suppress battery discharge when stored or not in use as well as a wake-up function, activated using an external push button, to extend the life of batteries and devices. 

In addition to the conventional LED-driven display, a terminal indicates the charging status, showing charging level by frequency. It also supports charging monitoring using a microcontroller. 

The XC6810 is equipped with a battery voltage monitoring function, which can directly monitor the battery voltage through a microcontroller, or a low battery voltage notification function. 

The wide input voltage range of 3.5 to 28V supports wireless power and energy harvester charging, confirmed Torex. For contact-type charging using a cradle, for example, one version has a terminal which modulates the power supply line for the charging status to be notified by two-wire communication. The charging status and charging control can be displayed through the cradle. 

Torex Semiconductor provides CMOS power management ICs for battery powered and energy efficient applications. The company specialises in CMOS analogue technology, with LDO voltage regulators, voltage detectors and DC/DC converters in its product portfolio.

Infineon combines Airoc Wi-Fi / Bluetooth in Nvidia Jetson for edge AI

Mon, May 30, 2022

Airoc Wi-Fi and Bluetooth connectivity provides Wi-Fi 6 / 6E and low power wi-Fi 5 connectivity to Nvidia’s Jetson system on modules (SoMs) for developers to accelerate artificial intelligence (AI) -enabled edge devices.

AI at the edge devices require reliable and instant Wi-Fi cloud connectivity for lifecycle management functions like deploying AI models through over the air (OTA) updates.

“In congested network environments, AI devices often encounter disconnections or low-data throughput, leading to poor user experience, explained Infineon. The Airoc Wi-Fi family delivers low latency, robust connectivity and high data throughput streaming, said Sivaram Trikutam, vice president, Wi-Fi product line at Infineon. 

The Wi-Fi will be used for AI applications which require real time blending effects from live action to computer-generated images or videos, such as gaming and AR / VR (augmented reality / virtual reality) in industry applications. In these applications, high-throughput and low-latency wireless transmissions are critical and require simultaneous processing and streaming of data. Infineon said its Wi-Fi 6E solution, operating in the 6.0 to 7.0GHz band, minimises latency and prevents interruptions due to congested wireless networks. This is combined with the fast processing power of the Nvidia Jetson platform for AI-enabled devices in, for example, robotics, smart cities, healthcare, industrial, retail, energy and agriculture where processing in the cloud is blended with edge processing.

The Airoc CYW4373, CYW5459x and CYW5557x are available to design now. The Nvidia Jetson compute platform is claimed to be the leading AI at the edge compute platform with over one million developers. With pre-trained AI models, developer software development kits and support for cloud-native technologies across the full Jetson line up, intelligent machine manufacturers and AI developers can build and deploy software defined features on embedded and edge devices.

Authenticator protects against counterfeiting with ECDSA and 1-Wire interface

Fri, May 27, 2022

To detect and protect products from counterfeiting or misuse, Analog Devices has introduced the DS28E30, a 1-Wire ECDSA secure authenticator. 

The authenticator combines a fixed-function cryptographic toolbox based on the industry standard FIPS 186 elliptic curve digital signature algorithm (ECDSA) with secure storage of keys and application data and the single-contact 1-Wire interface for minimal interconnect requirement. Authentication is based on challenge/response sequences. Analog Devices said that the authenticator is easy to integrate into new or existing designs.

The DS28E30 provides secure features to enable the use of limited life tools, sensors, and other peripherals. Features include a monotonic, non-resettable, decrement-only counter and 1kbit of general-purpose EEPROM. It can optionally be ECDSA protected to store application data including end-product life cycle information.

The DE28E30 has a wide operating range of 1.62 to 5.25V and a temperature range of  -40 to +85 degrees C.

The authenticator is supplied in a four-ball WLP with a 0.5mm pitch and measuring 1.2mm x 1.4mm. It is in full production and available now.

Analog Devices offers a suite of analogue and mixed signal, power management, radio frequency (RF), and digital and sensor technologies with more than 75,000 products in the industrial, communications, automotive, and consumer markets. ADI is headquartered in Wilmington, Massachusetts, USA.
