Platform protects comms between smart factory and the cloud

Thu, Mar 28, 2019

At the Hannover Fair next week, Infineon Technologies will present what it claims is the world’s first Trusted Platform Module (TPM) specifically for industrial applications. The Optiga TPM SLM 9670 protects the integrity and identity of industrial PCs, servers, industrial controllers or edge gateways, explains Infineon. It controls access to sensitive data in key positions in a connected, automated factory as well as at the interface to the cloud.

The TPM protects sensitive data in connected devices and lowers the risk of data and production losses due to cyber attacks. It also shortens time to market and reduces costs, claims Infineon. Using Infineon’s audited and certified TPMs, manufacturers of industrial devices can achieve higher security levels of the IEC 62443 standard and accelerate their certification processes. Infineon says they can also cut costs for maintenance of the devices through secured remote software updates.

The Optiga TPM SLM 9670 meets the TPM 2.0 standard of the Trusted Computing Group and is certified by an independent test lab in accordance with Common Criteria. Service life is 20 years firmware can be updated on the chip to meet long-term security risks that may be encountered in an industrial environment. The Optiga TPM SLM 9670 has an extended temperature range of -40 to +105 degrees C and is qualified according to the industrial JEDEC JESD47 standard.

The Optiga TPM SLM 9670 is manufactured at Infineon’s security-certified facilities in Germany and will be available in large volumes from the second half of 2019.

Infineon offers application-specific solutions for business PCs and routers, connected vehicles, or cloud applications. The Optiga TPM SLM 9670 will be presented for the first time at this year’s Hannover Messe (1 to 4 April). Infineon will run a demonstrator for energy-efficient and secured smart factories at the stand of Amazon Web Services (Hall 6, Stand F46).

Hall-effect sensor ICs enhance ADAS safety

Wed, Mar 27, 2019

Two Hall-effect sensor ICs have been announced by Allegro Microsystems for systems that require functional safety.

The APS11450 is a family of unipolar switch ICs and the APS12450 devices are bipolar latches. They are pin-compatible upgrades for existing three-wire Hall switch and latch ICs developed in accordance with ISO 26262:2011 with ASIL-B capability (pending assessment).

The magnetic sensors have integrated self-test features that are always active in the background while the system is running. This leads to very short fault detection times, says Allegro. The action is automatic, and the tests are executed, typically in 25 micro seconds, making them transparent to the host system. Allegro points out this is even in latches used in high-speed motors and encoders. The voltage-mode output communicates the sensor’s status (including the safe state), while remaining backward compatible with logic-level interfaces, application circuits, wiring, and firmware.

The APS11450 and APS12450 are designed to enhance automotive applications and intelligent motion systems, such as advanced driver assistance systems (ADAS) and encoders for windows, seat motors, seatbelt tensioners, and closure systems. The ICs are also suited for off-road vehicles, heavy equipment, human machine interfaces (HMI) and roll-over (bank angle) sensors, kickstands and driver controls in two-wheeled vehicles.

The APS11450 and APS12450 are qualified beyond the requirements of AEC-Q100 grade 0, says Allegro. They were developed to ISO 26262 as a hardware safety element with ASIL-B capability (pending assessment) for automotive safety systems.

When using the APS11450 or APS12450 devices, developers can achieve an ASIL-B (or higher) rating without redundant sensors, for smaller, less expensive systems.

Two package choices are available, with magnetic characteristics that match legacy Hall sensors. The monolithic ICs operate from 3.3 to 24V and at up to 175 degrees C junction temperature, surviving up to +35V inputs, reverse-battery (-30V), output shorts, load-dump, and other over-voltage transients. Allegro’s miniature LH package is a SOT-23W style package for surface mount applications and the UA version is a three-pin, single inline package (SIP) for through-hole mounting. Both packages are lead (Pb) -free, with 100 per cent matt-tin leadframe plating.

RZ/G Linux aims to reduce industrial control certification time

Wed, Mar 27, 2019

With the aim of reducing IEC 62443-4-2 user certification time by up to six months, Renesas Electronics has collaborated with Civil Infrastructure Platform Security Working Group in Linux Foundation to release a security option based on its RZ/G Linux platform.

According to the company, it will reduce the amount of time required for users to obtain certification under IEC 62443-4-2, the international standard for security technologies used to protect industrial control systems from cyber attacks.

Such cyberattacks on industrial control systems’ infrastructure, such as manufacturing plants and power stations are a serious threat which promoted the establishment of the IEC 62443 international security standard covering industrial control system operators, system integrators and equipment suppliers as well as enterprises and organisations involved in industry and public infrastructure. Within the standard, endpoint devices (sensors and programmable logic controllers – or PLCs) must be certified under IEC 62443-4.

To help developers overcome the certification challenges, the Renesas RZ/G Linux Platform security solution, together with the activities in Civil Infrastructure Platform (CIPTM) project, will enable users to reduce the time required for obtaining IEC 62443-4-2 certification by as much as six months.

Within the IEC 62443-4 standard, IEC 62443-4-1 deals with development process compliance and IEC 62443-4-2 deals with the technical compliance of the devices themselves. Renesas is working through the newly established CIP Security Working Group to develop secure open source software (OSS) that complies with IEC 62443-4-2, to establish guidelines for implementing security functions and applications using OSS, and to help create the testing procedures and testing environments necessary for obtaining IEC 62443-4-2 certification.

Renesas supports embedded Linux devices in the industrial field with the RZ/G Linux platform which combines an RZ/G microprocessor and a verified Linux package with long-term support. The security solution will include all the software and documentation necessary for obtaining IEC 62443-4-2 certification, confirms Renesas. It provides an optimal development environment for products employing the RZ/G Linux Platform.

The new IEC 62443-4-2-compliant security solution is scheduled to be available by the end of 2019, starting with the RZ/G2M microprocessor, with solutions for other RZ/G2 MPUs to follow.

Renesas will continue to provide solutions with IEC 62443-4 support while working to advance enhanced endpoint intelligence to develop shared technologies such as security technology and functional safety technology

Infineon claims industry’s first true 1000A voltage regulator for AI

Tue, Mar 26, 2019

Adding to its high current system chipset portfolio, Infineon claims to offer the industry’s first 16-phase digital PWM multiphase controller.

The XDPE132G5C extends the existing portfolio which enables currents of 500 to 1000A and above for next generation CPUs, GPUs, FPGA and ASICs used in artificial intelligence (AI) and 5G datacomms applications.

It has been introduced as CPU current requirements increase to enable next-generation AI and networking workloads, DC/DC voltage regulators to deliver more than 500A to the load. The XDPE132G5C has a true 16-phase digital PWM engine and an improved advanced transient algorithm to address these high phase count requirements, says Infineon. The true active current sharing between phases enables a reliable, compact and cost-saving design, with no need for extra logic doubler ICs.

The XDPE132G5C offers fine V out setting in 0.625mV increments to meet the demands of ASICs and FPGAs of V out control in less than 1mV steps, seen in communication systems today. The XDPE132G5C also supports auto-restart for communications with options to reduce remote site maintenance following power or system glitches.

The XDPE132G5C is packaged in a 7.0 x 7.0mm 56-pin QFN to accommodate 16 phases. It employs a full digital and programmable load line and is PMBus 1.3/AVS-compliant.

Infineon advises that it can be paired with TDA21475, the thermally efficient integrated current sense power stage, to efficiently deliver over 1000A.

The 70A-rated TDA21475 power stage is housed in a 5.0 x 6.0mm package. It provides efficiency of more than 95 per cent. The exposed top significantly reduces the R th(j-top) from 19 degrees C/W in the over-moulded package to 1.6 degrees C/W. This removes heat from the top of the package, for voltage regulator power density and optimal phase count and footprint. The TDA21475 also offers smart over-current and over-voltage protection and delivers temperature and current information to the XDPE132G5C controller.

The company also offers the IR35223 true 10-phase PWM digital controller. This controller provides a cost-effective option for voltage regulation up to 500 A. The IR35223 is housed in a 6.0 x 6.0mm, 48-pin QFN package and provides advanced transient performance and telemetry features including PMBus 1.3/AVS bus compliance.
