Small sized amplifier but high in performance

Texas Instruments (TI) has introduced the industry’s smallest operational amplifier (op amp) and low-power comparators at 0.64 mm2. Being the first amplifiers in the compact X2SON package, the new TLV9061 op amp and TLV7011 family of comparators enable engineers to reduce their system size and cost.

The noticeable feature of the new amplifiers is that their size does not affect the performance. They offer high performance in a variety of Internet of Things (IoT), personal electronics and industrial applications, including mobile phones, wearables, optical modules, motor drives, smart grid and battery-powered systems.

As part of TI’s small-size amplifier portfolio these new devices enable engineers to design smaller systems, while maintaining high performance. They allow possibility of industry-leading package options and many of the world’s smallest op amps and comparators.

With a high gain bandwidth (GBW) of 10 MHz, fast slew rate at 6.5 V/µs and low-noise spectral density of 10 nV/√Hz, the TLV9061 op amp is designed for use in wide-bandwidth, high-performance systems. Additionally, both devices support rail-to-rail inputs with low-voltage operation down to 1.8 V, enabling ease-of-use in battery-powered applications.

In addition to its tiny size, the TLV9061 op amp also features integrated EMI filtering inputs. This helps provide resilient performance for systems prone to RF noise, while significantly reducing the need for external discrete circuitry.

Two times lower offset drift and typical input bias across a full temperature range, -40 to 125 degrees Celsius, creates a more precise signal chain solution compared to other small devices. With power as low as 335 nA and fast propagation delay down to 260 ns, the TLV7011 family of nano-power comparators enable low-power systems to monitor signals and respond quickly.

Industrial IoT initiative to improve Efficiency and Safety in the Rail Industry

Global demand in the transportation sector continues to outpace supply and is recognized as a key area for economic growth. Leveraging Penteon’s electronic sensor development, telecommunications gateway infrastructure and enterprise cloud expertise, the Industrial IoT initiative will open a new era in low-cost, highly-secure rail sector services.

Penteon Corporation has announced a new Industrial IoT initiative to develop custom industrial sensing solutions for locomotives, rail cars and track-side equipment in partnership with Wabtec Corporation. Aging rail systems and lack of real-time data collection have become limiting factors in addressing this increasing demand. Embracing new technologies to acquire and analyze information across their operations and using that information to become more efficient and effective will deliver a more responsive and agile operating environment to rail operators.

The solutions planned for development by Penteon and Wabtec include data collection from rail equipment and systems to develop a real-time, holistic view on the health and status of locomotives, rail cars, and track-side systems. This IIoT project capitalizes on the more than 25 years of remote sensing engineering within Penteon and will deliver cost effective, secure and efficient solutions leveraging Penteon’s unique “Sensing as a Service” business model.

“Penteon’s new, low-power, long-range wireless network, which it is building in partnership with Landmark Infrastructure Partners, will also play a key role in delivering reliable cost-effective services,” said Clay Perreault, Chief Executive Officer of Penteon. “Our work with Wabtec is a truly collaborative, consultative relationship, which involves dedication from both parties.  By working side-by-side with our customers, we’re able to drive the best outcomes at an accelerated pace.”    Read more…

Presto Protects IoT Chips With Secure Manufacturing & Test

Supporting the growing need for IC security in IoT applications, Presto Engineering is offering a comprehensive manufacturing and test service that is tailored to ensure IoT chips are made to high standards of security.

Presto says it can manage the entire chip manufacturing and testing process to make chips with levels of security right up to that needed for banking standards.

IoT devices’ connection to the Internet provides a potentially vulnerable route for hackers. Presto notes that an IoT chip connected to the internet should have two levels of security built into the design of the ASIC itself to stop unauthorized access.

The first is Cryptography to protect communication and maintain the confidentiality and integrity of data as it moves across the network. The second is Authentication to verify that only authorized computers or people have access.

Turning the design into a chip requires a highly secure manufacturing supply chain. Presto claims “it can manage the entire chip manufacturing and testing process to make chips with levels of security right up to that needed for banking standards, including the secure provisioning of the cryptographic keys. The latter ensures that processors will only execute code and updates identified with the correct secret keys.”

Handling these securely in the manufacturing supply chain is vital to an effective security strategy and is covered by the Common Criteria for Information Technology Security Evaluation standards. These range from the basic Evaluation Assurance Level 1 to Level 7 for government and military, with Level 5 being typical for banks, payment systems, and other highly demanding commercial application.

OPTIGA Trust X Protecting the Internet of Things

The fact that the devices that are online can be attacked, is an area of concern for all. Hitting right on the nail, Infineon Technologies AG is adding the OPTIGA Trust X to its OPTIGA Trust family. This hardware-based security solution Trust X, provides robust security to the diverse applications in the Internet of Things (IoT), ranging from smart homes, smart offices to drones.

“In the Internet of Things, we must think about security from the very beginning,” says Thomas Rosteck, Division President Chip Card & Security at Infineon. “Hardware-based security provides the necessary protection against attackers, as critical data can be separated from operations. Thanks to OPTIGA Trust X, we make it easy for manufacturers to integrate robust security into their IoT devices.”

The security solution covers a broad range of applications: mutual authentication, secured communication, data storage protection, assignment of keys, lifecycle management, power management, secured updates and integrity protection for the platform.

The OPTIGA Trust X can be used in extreme temperatures from extended range from -40°C to +105°C. It is therefore also suitable for deployment in harsh industrial environments. Device manufacturers save time and costs thanks to the plug-and-play concept enabling even companies without specialist know-how in the field of security.

The company shared that the developers of intelligent streetlights at eluminocity also rely on OPTIGA Trust X from Infineon. They use it to protect the streetlights against unauthorized access – from the cloud down to device level. It’s already being used at the Hong Kong Science Park, where it offers flexible street lighting, a charging station for electric cars, and air measurement sensors.

Next use case shared by the company was that of the “Digital Product School” where UnternehmerTUM, employees from Infineon, Nokia and TÜV SÜD have together with students jointly developed the first drone with hardware-based security. Its aim is to provide emergency services with reliable information before they arrive. Here too, sensitive data must be protected, the control unit must be authenticated reliably and attacks be repelled.

The developers are using the OPTIGA Trust X to deliver efficient protection against attackers and serves as a trust anchor.
