PHY is integrated for fibre optic automotive networking

Thu, Nov 19, 2020

Believed to be the first device for optical in-vehicle connectivity incorporating a transceiver IC, optoelectronics and optics, the KD7051 is an integrated fibre optic transceiver (FOT) from KDPOF.

The integrated FOT is a 100Mbit per second optical port in one single component. “By constructing the ASIC IC, photodiode and LED as one single device, we significantly reduce cost and footprint for automotive Ethernet connectivity at 100 Mbits per second,” said Carlos Pardo, CEO and co-founder of KDPOF. “The decreased number of parts also reduces the effort in testing and qualification,” he added.

The KD7051 reduces cost, compared to shielded twisted pair (STP) of copper wires, said KDPOF. There are no margin stacking between links in the supply chain and supply chain simplification, which offers competitive pricing for EMC critical or galvanic isolated critical links, says KDPOF. Applications include battery management systems, camera and sensor links, fast Ethernet links and smart antenna links.

KDPOF’s KD7051 transceiver IC offers a complete FOT design, which reuses low cost MEMs encapsulation and allows SMD reflow assembly with 8.0 by 7.0mm LGA components. The FOT is shielded against electromagnetic radiation. Fibre connection is via a simple plastic connector placed on top. The temperature range, from -40 to +105 degrees C, conforms with harsh automotive environmental requirements. It has a vibration class of V2 and withstands motor conditions. According to KDPOF, the device endures water without sealing. Shielding is integrated into the PCB component to strengthen EMC performance even with the ECU shield case removed. The first prototypes are available now.

The plastic optical fibre has a large diameter, making it more cost-effective to manufacture and install. During car assembly, the optical harness can be installed in the same process as the copper harness to ease installation.

Fabless semiconductor supplier KDPOF provides innovative high speed optical networking for harsh environments. It makes Gbit communications over fibre optics a reality, and supplies 1Gbit per second POF links for automotive, industrial, and home networks.

The company was founded in 2010 in Madrid, Spain, and offers a cost-effective technology as either ASSP or IP to be integrated in SoCs. The adaptive system works with a range of optoelectronics and low cost large core optical fibres, for a low risk, low cost, reduced time to market for vehicle manufacturers.

Automotive -grade proximity sensors prevent false triggers

Tue, Nov 17, 2020

Two integrated automotive-grade proximity sensors with high resolution up to 20 micron for force sensing applications have been released by Vishay Intertechnology. Each combine a photodiode, amplifier and ADC circuitry in a 4.0 by 2.36mm surface mount package with a low 0.75mm profile. The VCNL3030X01 features an on-board infrared emitter (IRED) while the VCNL3036X01 is designed to be used with up to three external IREDs, for which an on-board driver with internal logic is provided.

They are intended for use in automotive, consumer, smart home, industrial, office products and toys. The AEC-Q101-qualified devices provide higher resolution compared to previous generation sensors at a lower cost, says Vishay Intertechnology. The VCNL3030X01 and VCNL3036X01 can be used for force sensing applications in steering wheel controls, laptop smart power buttons and multi-force trackpads, and touchpads for IoT devices and kitchen appliances. The sensors prevent false triggers and even allow users to wear gloves, advises Vishay. The VCNL3036X01 is designed to work with external IREDs, for increased flexibility for product design.

Both VCNL3030X01 and VCNL3036X01 sensors support the I²C bus communication interface and the programmable interrupt function allows designers to specify high and low thresholds, which reduces the continuous communication with the microcontroller. The proximity sensors have selectable 12-bit and 16-bit outputs, and use intelligent cancellation to eliminate crosstalk. There is also a smart persistence scheme which ensures accurate sensing and faster response time. The VCNL3030X01’s emitter wavelength peaks at 940nm and has no visible ‘red-tail’, says Vishay.

The VCNL3030X01 and VCNL3036X01 have an IRED / LED pulse current of 200mA, a supply voltage range of 2.5 to 3.6V and an I²C bus voltage range from 1.8 to 5.5V. For force sensing applications, the sensors offer the flexibility to fine-tune the current for short displacements.

The devices are RoHS-compliant, halogen-free, and Vishay Green.

The VCNL3030X01 and VCNL3036X01 proximity sensors are sampling now and available in production quantities with lead times of six to 12 weeks for large orders.

Automotive OEMs and their module suppliers can use TrustAnchor to upgrade existing designs to meet security requirements, says Microchip. The cryptographic security IC supports in-vehicle network security solutions such as secure boot, firmware update and message authentication, including controller area network (CAN) MAC at bus speed, says Microchip.

The rise of in-vehicle network connections like Bluetooth and LTE/5G, means convenience but also more vulnerabilities in an automotive system. The TrustAnchor100 (TA100), CryptoAutomotive security IC helps OEMs and their module suppliers to simplify the upgrade of existing designs to meet security requirements for future generations.

To comply with new security specifications, automotive designers have to revise the vehicle’s electronic control units (ECUs) with secure hardware. Using single chip, dual core hardware security module (HSM) devices for this requires OEMs and module suppliers to rework application software to integrate the security element. This can introduce security holes, which can be overcome by third party security software but it will increase development costs.

The TA100 provides an alternative in-vehicle network architecture implementation for secure boot and message authentication. It has been approved by OEMs around the world as a solution for EVITA (e-safety vehicle intrusion protected applications) medium and full HSM requirements. Its feature set was designed following the review of OEM cybersecurity specifications. Microchip also offers security specification and request for quote (RFQ) review services to assist Tier 1s in developing educated responses.

According to Microchip, the TA100 removes the challenges associated with secure code development and provisioning by offering pre-programmed cryptographic internal application code provisioned with unique asymmetric key-pairs and associated x.509 certificates, thereby reducing risk, cost and time to market.

The device has high resistance to attack through intensive third-party vulnerability assessments, says Microchip and is AEC-Q100 Automotive Grade-1-qualified, FIPS 140-2 CMVP Security Level 2-rated and Physical Key Protection Level 3-certified. It has also achieved the highest possible vulnerability assessment rating of Joint Interpretation Library (JIL) High. The TA100 provides software components like AUTOSAR drivers, MCALs and Microchip’s CryptoAuthentication library for seamless integration into AUTOSAR, the industry standard OS, or customised software stacks for crypto functions.

The TA100 offers AUTOSAR-compliant MCAL drivers that can be integrated into an AUTOSAR software stack. A full AUTOSAR reference stack is available, enabling automotive vendors to deploy the latest crypto standards into automotive systems within standard automotive production environments, explains the company. MikroBUS-compatible socket boards are also available.

The TA100 is available in an eight- and 14-pin SOIC packages.
