Controller provides safety functions for widescreen automotive displays

Fri, Dec 11, 2020

Two display controllers from Socionext have enhanced security support for high resolution, wide format displays.

The SC1702 display controller meets the automotive market’s demand for high-resolution widescreen automotive displays. Socionext has added a display controller to its SC1701 series, providing low-cost, optimal safety functions for meter clusters. Both display controllers deliver scalable in-vehicle remote display systems with high levels of safety, says the company.

The use of automotive displays is rapidly expanding in instrumentation and vehicle control operations, including meters, climate controls and other dashboard indicators integrated into graphics, as well as head-up displays (HUDs) and e-mirror displays, ranging from conventional small displays to large format, wide screens with some spanning across the entire dashboard.

The SC1702 is capable of transferring data at rates of up to 12Gbits per second, using APIX 3 technology. It is equipped with a newly developed panel interface port (PIP) that supports advanced, high-resolution, wide landscape format displays, such as 8K x 1K, which cannot be supported with conventional interfaces. It is also designed to conform to the HDCP 2.3 encryption technology, making it possible to effectively use rich, 4K-resolution content for multi-displays in a vehicle.

The SC1702 can detect display abnormalities that are unobservable with current technology, advises Socionext. In addition to the conventional safety features, displays can now recognise panel link loss, inconsistencies of CRC of pixel data and other behaviours at the source drivers and gate drivers, enhancing the capabilities to meet further safety requirements.

The SC1701BH5-300 has been added to the SC1701 family, providing additional functions to existing meter systems. Safety features include multi-window signature unit, picture freeze detection, and watchdog, as well as the 2D rendering capability of Deep Color (30 bpp) built-in graphics engine, at a competitive price, says Socionext.

The SC1701BH5-300 is available in an EP-LQFP-216 package, measuring 24 x 24mm and the SC1702AK3 is available in an HS-BGA-319 package, measuring 23 x 23mm.

The join the SC1701BK3-100 and SC1701BH5-100 display controllers.

Samples of the SC1701BH5-300 are now available. Sample shipment of the SC1702AK3 will start in February 2021.

Radar sensor suite has all-round sensing for vehicles

Wed, Dec 09, 2020

Sensing to cover all radar segments from Europe’s NCAP (New Car Assessment Programme) to 4D imaging radar is provided by a suite of automotive radar sensor chipset suite by NXP.

The NXP radar sensors are built on 16nm FinFET and 40nm RFCMOS technology. The include the RFCMOS 77GHz radar transceivers, the S32R45 high-performance radar processors for imaging radar and the S32R294 radar processor for corner and front radar applications

The processors and transceivers offer automotive manufacturers flexible and scalable configurations that address NCAP requirements for corner and front radar applications as well as what is claimed to be the first commercially viable path to volume production for 4D imaging radar.

4D imaging radar expands radar’s capabilities from measuring range and speed to include direction, angle of arrival, and elevation measurement.

NXP offers imaging radar, which “significantly enhances radar’s performance”. It delivers multi-modal capabilities and extends today’s L2+ features, such as highway pilot and lane change assistance, by offering very high resolution images for precise environmental mapping and scene understanding. This is an important part of enabling full autonomy in urban settings, says NXP.

NXP’s new purpose-built S32R45 radar processor and the TEF82xx transceivers deliver the fine angular resolution, processing power and range required to distinguish between small objects in the distance and separate and classify vehicles and vulnerable road users (e.g. cyclists or pedestrians) in crowded environments. This capability is targeted at providing better driving decisions.

The suite also provides scalability for long-range front radar and advanced multi-mode use cases, e.g. simultaneous blind-spot detection, lane change assistance and elevation sensing. These advanced applications require extended range and significantly enhanced angular resolution to detect and separate multiple objects simultaneously. The new S32R294 radar processors, combined with the NXP TEF82xx transceivers provide a scalable solution to address NCAP, advanced corner radar and long-range front radar sensor requirements. They can also be tailored for individual use cases.

“Radar has evolved from just detecting other cars’ velocity and distance to providing imaging radar’s high-resolution object and feature detection for precisely mapping the car’s surroundings,” said Torsten Lehmann, executive vice president and general manager, Radio Frequency Processing, NXP.

NXP claims to be the first company to broadly deliver 77GHz RFCMOS radar technology in high volume, mass production and says it helps customers optimise the total cost of ownership with scalable, re-useable radar systems.

Target applications are in traditional automotive manufacturers, focused on automated driving levels one to three, and for mobility as service innovators developing robotaxi and safe delivery applications for levels four and five automation.

The devices are sampling now, with mass production expected in 2021.

Mach-NX FPGA is designed for cyber-resilient systems

Wed, Dec 09, 2020

Lattice Semiconductor has added support for ECC 384 and SPDM protocols in its second generation of secure control FPGAs. Following on from the secure control of the Lattice MachXO3D FPGAs, released last year, the FPGAs are the third family in 12 months that have been developed on the Lattice Nexus FPGA platform. The company says the Mach-NX FPGAs deliver heightened security features and the fast, power-efficient processing needed to implement a real time hardware root of trust (HRoT) on future server platforms, computing, communications, industrial and automotive systems.

According to the company, the Mach FPGA families can simplify and accelerate implementation of technologies, such as ECC 384 and data security protocols like SPDM, to secure platforms against cyber attack and IP theft.

Esam Elashmawi, chief strategy and marketing officer at Lattice, commented: “Securing systems against unauthorised firmware access goes beyond establishing a HRoT at boot. It also requires that components used to build the system are not compromised as they move through the global supply chain. When combined with the additional protection afforded by our SupplyGuard security service, Lattice Mach-NX FPGAs can protect a system throughout its entire lifecycle: beginning at the time components start moving through the supply chain, through initial product assembly, end-product shipping, integration, and throughout the product’s operational lifetime.”

The Mach-NX FPGAs combine a secure enclave (a 384-bit hardware-based crypto engine supporting reprogrammable bitstream protection) with a logic cell and I/O block. The enclave helps secure firmware, and the logic cell and I/O block enable system control functions such as power management and fan control. The FPGAs can verify and install the over-the-air firmware updates to keep systems compliant as security guidelines evolve and protocols are introduced.

The parallel processing architecture and dual-boot flash memory configuration provide the near instantaneous response times needed to detect and recover from attacks (a level of performance beyond the capabilities of other HRoT platforms like MCUs), reports Lattice.

The FPGAs will support Lattice Sentry, a software stack of customisable embedded software, reference designs, IP and development tools. This accelerates the implementation of secure systems to comply with NIST SP-800-193, Platform Firmware Resiliency (PFR) guidelines and MCTP-SPDM.

The Lattice SupplyGuard supply chain security subscription service tracks locked Lattice FPGAs through their entire lifecycle, from the point of manufacture, through transport via the global supply chain, system integration and assembly, initial configuration, and deployment.

The Lattice Propel design environment accelerates design of a customised, PFR-compliant HRoT solution. It uses a GUI-based development environment that allows developers to create PFR solutions while minimising the need to write RTL code, explains Lattice.

MCUs are validated for security, says NXP

Tue, Nov 24, 2020

Microcontrollers (MCUs) from NXP Semiconductors have received Level 2 certifications by both the PSA Certified scheme co-developed by Arm and the GlobalPlatform Security Evaluation Standard for IoT Platforms (SESIP) using the secure protection profile for embedded processors. The LPC55S16 MCU is intended for IoT and Industrial edge applications, device security and data protection.

The LPC55S16 MCU is part of the NXP EdgeVerse computing and security portfolio and a member of the general purpose LPC5500 MCU series based on the Arm Cortex-M33 core. The MCU series is based on 40nm NVM process technology, and offers advanced security and mixed-signal capabilities.

The LPC55S16 MCU achieved PSA Certified Level 2, based on an assurance framework to showcase robustness of the security. The certification enables device manufacturers to reduce additional security testing and improve time to market. The laboratory evaluation against the PSA Root of Trust (PSA-RoT) security claims to demonstrate that the device can protect against scalable software attacks.

To achieve GlobalPlatform SESIP 2, the LPC55S16 MCU underwent source code analysis and penetration testing and was validated by an independent certification body. SESIP certification helps assure product security claims are tested and verified, and provides evidence of the LPC55S16 MCU’s resistance to basic attack potential. SESIP allows for customers to re-use the LPC55S16 MCU validation results in the certification process for their end applications.

The LPC55S16 MCU integrated security features include Arm TrustZone technology, which enables system-wide software protection with the ability to securely isolate peripherals to reduce the risk of attack on critical components. There is also an AES-256 accelerator which provides confidentiality and a secure hash algorithm (SHA2) accelerator provides integrity of secure communications and secure boot. A Prince module offers real-time encryption and decryption of the on-chip flash to provide both secure storage of data and asset protection of software IP.

The Casper Crypto co-processor enables hardware acceleration of various asymmetric cryptographic algorithms to establish secure connections, while a physical unclonable function (PUF) uses dedicated on-chip SRAM to construct unique device root keys (64 to 4096 bits) for secure storage. Other protection features are a 128-bit unique device serial number for identification (UUID) and a true random number generator (TRNG). A code watchdog enables integrity checking of execution flow of the firmware and a debug authentication protocol is provided for secure debugging.

The LPC55S16 MCU is part of the Certified EdgeLock Assurance program. Both the SESIP and PSA Certified testing and certifications were conducted by the independent security evaluation laboratory, Brightsight.

The i.MX LPC55S16 MCU family is available now.
