OmniVision increases image sensors and adds cybersecurity

Wed, Jan 20, 2021

Digital imaging specialist, OmniVision Technologies, has added the OX03F10 automotive image sensor to its family for automotive viewing cameras.

The ASIL-C sensor maintains simultaneous 140dB HDR and LED flicker mitigation, and offers increased resolution and cybersecurity to support vehicle designers transition from Level 2 and Level 3 advanced driver assistance systems (ADAS) to higher levels of autonomy.

The OX03F10 maintains the combination of a large 3.0M pixel size with a high dynamic range (HDR) of 140dB featured in the company’s other automotive image sensors in the series. It is also claimed to have the best LED flicker mitigation (LFM) performance for minimised motion artefacts. The sensor is offered in a 1/2.44-inch optical format and features a four-lane MIPI CSI-2 interface.

It is also believed to be the first viewing image sensor with HDR and LFM that can deliver the wide vertical array resolution of 1920 x 1536p at the highest rate of 60 frames per second. This provides the high image quality needed when feeding surround view system (SVS) captures into autonomous, machine vision systems, explains OmniVision. The OX03F10’s wider vertical array is also important in e-mirror applications, for wider coverage and blind-spot elimination.

“In addition to excellent image quality across all lighting conditions, higher resolution and cybersecurity are becoming must haves for the designers of viewing cameras—particularly for SVS,” said Kavitha Ramane, staff automotive product marketing manager at OmniVision. The OX03F10 operates over the entire automotive temperature range and has ASIL-C functional safety.

The 3Mpixel resolution and cybersecurity features are required to integrate viewing cameras into autonomous vehicle systems. Cybersecurity ensures the images supplied to autonomous systems have not been altered, and augmented reality (AR) can take advantage of the OX03F10’s capabilities, for use within the vehicle, including in infotainment systems.

The OX03F10 also maintains the industry’s smallest package size, says OmniVision, and low power consumption, so that cameras that continuously run at 60 frames per second, can be positioned even in the tightest spaces. The image sensor also retains the family’s basic image processing capabilities, including defect pixel correction and lens correction. The integrated HDR and LFM engine (HALE) algorithm is the only imaging technology that can simultaneously provide top HDR and LFM performance, claims OmniVision. The result is high image quality for automotive viewing applications, including SVS, rear view cameras (RVC) and e-mirror camera monitoring systems (CMS), across all lighting conditions and in the presence of flickering LEDs from headlights, road signs and traffic signals.

OmniVision’s Deep Well, dual conversion gain technology enables the OX03F10 to capture significantly lower motion artefacts than competing sensors offering 140dB HDR. The split-pixel LFM technology with four captures offers the best performance over the entire automotive temperature range, claims OmniVision.

The viewing camera image sensors have OmniVision’s PureCel Plus-S stacked architecture, which provides pixel performance advantages over non-stacked technology. For example, explains the company, 3D stacking allows a boost to pixel and dark current performance, for a “significant performance improvement” over the prior generation of OmniVision’s viewing camera sensors.

This OX03F10 image sensor is available now for limited sampling in a-CSP and a-BGA packages, and is planned to be AEC-Q100 Grade 2-certified.

Tri-band chipset opens access to 6GHz spectrum, says NXP

Tue, Jan 19, 2021

The CW64 Wi-Fi 6E tri-band SoC from NXP is designed for access points and service provider gateways and enables end network devices to take full advantage of the 6GHz spectrum. The 6GHz band increases capacity in wireless networking and expands spectrum available for Wi-Fi by up to 1.2GHz.

This is the first Wi-Fi 6E Tri-Band SoC from NXP to support the 6GHz band to provide greater capacity in wireless networking, as congestion increases in the legacy 2.4 and 5GHz bands. It supports 160MHz channel bandwidth with PHY rates of 4.8Gbits per second and over 4Gbits per second of real-world throughput

The 4×4 Wi-Fi device has four spatial streams and 160/80/40/20MHz channel bandwidth, with uplink and downlink orthogonal frequency division multiple access (OFDMA) and uplink and downlink Multi-user, multiple input, multiple output (MU-MIMO) technology.

The CW641 is the first of six planned devices in the series. It enables increased speeds of over 4Gbps and multi-user performance in the new 6GHz band, providing greater capacity and lower latency. Adding 6GHz capabilities to gateway platforms gives service providers options to efficiently partition available bandwidth across devices to ensure optimum user experience for a wide range of applications.

Web authentication IC to make NFC authentication scalable

Fri, Jan 15, 2021

Swiss semiconductor company, EM Microelectronic, announces full volume production of em|linq, the NFC tag authentication IC. em|linq offers to brands the possibility to engage with their customers via NFC and to offer advanced product authentication.

NFC tags are a popular support for consumer engagement, turning any smartphone into a portal for accessing brand content. When the NFC tag content is dynamic, the tags also provide enhanced protection against cloning.

Scalability requires robust, cost-effective products but the authentication component adds cost and complexity typical to smartcards, making the return on investment proposition more difficult. In response, em|linq combines powerful cryptographic mechanisms typically reserved to smartcard products with the convenience and affordability of RFID products, says EM Microelectronic.

It is based on proven, open standards, allowing for full degree of freedom in the implementation of the authentication service. The key management and provisioning. critical for the security architecture, can be handled and fully controlled by the company who implements the solution, regardless of its position in the value chain, whether inlay or label manufacturer, integrator, brand or retailer.

Programming the cryptographic keys into the chips is segregated from programming the URL for the authentication service, providing additional flexibility and security for the system implementation.

The IC also opens up integration possibilities for electronic labels. Its small form factor provides superior mechanical robustness, says EM Electronic. Its power efficiency enables small antenna form factor to enhance communication performance. Electrical characteristics are compatible with most of the antenna designs on the market, reducing the engineering effort.

The authentication engine is built on top of a traditional RFID architecture rather than by simplifying a cumbersome smartcard one. Adding the authentication functionality remains an extension of a traditional RFID use case, with no unnecessary overhead. The tags are produced using the same process flow and with the same quality and cost-effectiveness as the standard RFID products. EM Electronic says its RF performance allows for very small inlay constructions, for ease of integration and to reduce the cost.

em|linq is NFC Type-2 compliant. Optimised cryptographic hardware implementation provides best-in-class web authentication brand protection to consumers’ smartphones, claims EM Electronic, using a dynamically generated HMAC-SHA1 code appended to the URL stored in the NDEF container.
