For safety-critical automotive applications, Murata offers the SCHA600, six degrees of freedom (DoF) xyz axis MEMS inertial sensor with patented self-test function for continuous monitoring.

The single package sensor offers cm-level accuracy for vehicle dynamics and position, for safe, robust and verified autonomous driving and in advanced driver assistance systems (ADAS).

The SCHA600 is qualified to AEC-Q100, includes advanced self-diagnostic features and complies to ASIL-D.

With an Allan variance down to 0.9 degrees/h at room temperature and gyro RMS noise level below 0.007 degrees/s, the sensor is claimed to deliver best in class performance for automotive applications in regard to bias stability and noise. The orthogonality of the measurement axis is calibrated at Murata to save systems integrators time and money.

The SCHA600’s failsafe functions and error bits for diagnostics include internal reference signal monitoring, checksum techniques for verifying communication and signal saturation/over range detection. Its component-level dynamic cross-axis calibration enables better than 0.3 degrees cross axis error over temperature.

The three-axis accelerometer contains a diagnostic feature of a continuously operating self-test function to monitor the sensor during measurement. This patented self-test function verifies the proper operation of the entire signal chain from MEMS sensor movement to signal conditioning circuitry for every measurement cycle.

The component is supplied in a SOIC housing body with dimensions of 18.7 mm x 8.5 mm x 4.5 mm and with 32 pins. Operating temperature range is −40 to +110 degrees C. Samples are available now.

Murata manufactures electronic components, modules and devices. The company’s range includes ceramic capacitors, resistors/thermistors, inductors/chokes, timing devices, buzzers, sensors and EMI suppression filters. As well as ceramic capacitors, the company manufactures Bluetooth and Wi-Fi modules, board-mount DC/DC converters and standard and custom AC/DC power supplies.

UltraSoC and Canis Labs address automotive cybersecurity

Thu, May 28, 2020

UltraSoC and Canis Automotive Labs have partnered to develop hardware-based intrusion detection and mitigation techniques to secure the CAN bus for automotive cybersecurity.

The project is to address the lack of security features within the CAN bus, which is commonly used to interconnect in-vehicle systems such as brakes, steering, engine, airbags, door locks, and headlights. This includes automatic hardware anti-spoofing, defence against bit-level attacks such as the bus-off attack and bit-glitching and resistance to denial of service (DoS) attacks. The collaboration deploys Canis Labs’ CAN-HG technology, a compatible augmentation of the standard CAN bus protocol that includes bus guardian security features which can carry payloads 12 times larger than standard CAN frames.

When combined with UltraSoC’s semiconductor IP for detection and mitigation of cyber threats, CAN-HG allows designers to secure CAN bus designs at the hardware level. The cybersecurity capabilities employ fast bits within the CAN-HG augmented part of a CAN frame to add security information to CAN frames. This can be used by UltraSoC’s protocol-aware monitoring hardware to identify and block suspicious or unauthorised traffic traveling over CAN. These new capabilities will be refined and proved for deployment as part of Secure-CAV, a project that seeks to improve the safety and security of tomorrow’s connected and autonomous vehicles (CAVs).

Aileen Ryan, UltraSoC CSO, commented “Incorporating Canis Labs’ innovative CAN-HG technology into UltraSoC’s products allows us to secure the vehicle ‘from the inside out’ within the underlying electronic hardware.”

Ken Tindell, Canis Labs’ CTO, added: “The most effective way to protect a CAN bus from attacks is to deploy a hardware security device – or better still, use semiconductor IP to incorporate hardware protections into the underlying system”.

CAN is used in the automotive industry but also in industrial, cyberphysical and robotics applications, where safety is paramount. While CAN is physically robust, it lacks cybersecurity features.

Most existing approaches to CAN security are software-based, meaning that they are often unable to react quickly enough to prevent protocol-level attacks. The hardware based Canis Labs / UltraSoC solution can react quickly to prevent an attack from completing, said UltraSoC. Many exploits rely on creating a window of opportunity during which the system is in a vulnerable or unknown state. A fast reaction time can eliminate this window and significantly improve the overall robustness of cybersecurity defences. Secondly, CAN bus is used in many cyberphysical systems, in which elapsed time equates to distance travelled. A faster response time has significant benefits in terms of mitigating the physical consequences of an attempted intrusion, better protecting the safety of citizens and infrastructure.

Dialog Semiconductor combines Wi-Fi and BLE in DA16600 modules

Thu, May 28, 2020

Leveraging the DA16200 VirtualZero Wi-Fi technology with SmartBond Tiny DA14531 Bluetooth, Dialog Semiconductor claims that the DA16600 module offers best-in-class battery life and configurability.

The DA16200 SoC was purpose-built for battery-powered IoT applications, including connected door locks, thermostats, security cameras and other devices that require an always-on Wi-Fi connection, but may be only used sporadically. Its VirtualZero technology enables the industry’s lowest level of power consumption for Wi-Fi connectivity, so that even continuously connected devices can achieve up to five years of battery life in many use cases, said Dialog Semiconductor. The DA16600 module also leverages the capabilities of the SmartBond TINY DA14531, claimed to be the world’s smallest and lowest power Bluetooth SoC.

The DA16600 Wi-Fi and Bluetooth Low Energy module combines the two complex protocol stacks, eliminating issues often caused by the co-existence of two radios at 2.4GHz in the same design, said Dialog. Bluetooth Low Energy provides ease of configurability for Wi-Fi in the application, simplifying the task of Wi-Fi set up for the end user. The module design is optimised to be incorporated into an embedded IoT product using is a simple set of guidelines provided by Dialog.

The module is certified for worldwide operation, including certifications for FCC, IC, CE, Telec, Korea and SRRC. It is also Wi-Fi Certified for interoperability.

Evaluation boards and a complete software development kit (SDK) are available for the DA16600 module via DigiKey. The SDK includes sample applications, provisioning apps, AT command library and power management tools.

NFC reader IC delivers rapid car key response and extended range

Thu, May 28, 2020

STMicroelectronics says the latest addition to the ST25R NFC reader ICs deliver rapid car-key response and reliable connections over extended distances. The ST25R3920 complies to the recently published Digital Key Release 2.0 specification by the Car Connectivity Consortium and certified by NFC Forum.

Digital keys let drivers conveniently lock and unlock their cars using smartphones, and support added-value features including easy sharing and management of access privileges for other users. The keys could also enable new vehicle-ownership models, including car subscription services.

The Car Connectivity Consortium (CCC) Digital Key Release 2.0, relaying on NFC, offers the ability to use the key while the phone battery is so low that normal device operation is disabled.

The ST25R3920 uses Dynamic Power Output (DPO) and Noise-Suppression Receiver (NSR) technologies to increases RF output power and enhance input-circuit design for rapid car-key response, said STMicroelectronics.

With DPO, the device operates at up to 1.6W continuous RF output power and 2.5W short-term input peak, to maintain reliable NFC connections over distance with a small antenna. ST’s NSR technology increases immunity to interference from noise sources to simplify EMI and is also claimed to ease certification. Automatic antenna tuning compensates for changes in the RF environment to maintain the best possible connection to the user’s smartphone, while low-power key-signal detection with inductive wakeup minimises load on the battery when the key is not being used.

The ST25R3920 has been designed for space-constrained locations that severely limit the maximum antenna size, as a result in can be positioned in door handles, B-pillar, or centre console.

The ST25R3920 supports the CCC Digital Key Standardization Release 2.0, the architecture endorsed by the world’s leading carmakers, smartphone manufacturers, and electronics suppliers. ST is a CCC member and plays a key role in setting NFC standards as a member of the NFC Forum board, various working groups, and ISO 14443 and ISO 15693 task forces.

The IC is also certified by NFC Forum and can work as an NFC reader or NFC universal device. Compliance with NFC Forum standards for pairing applications, as well as EMVCo 3.0 standards, allows its use as an in-car contactless-payment terminal for services such as electric-vehicle charging. In addition, a Qi wireless charging NFC-card protection algorithm enables safe wireless charging of portable devices.

The ST25R3920 is in production now.
