Software development model for the ISO/SAE 21434 standard

In the functional safety world, once a system is developed, it remains protected as long as the system is in service. In contrast, the security world demands that software must continue to defend a system against constantly evolving methods of attack long after a product is released. With the explosion in demand for in-vehicle connectivity, … Read more

ISO/SAE 21434: Software certification for automotive cybersecurity

Automotive embedded applications have traditionally been isolated, static, fixed-function and device-specific implementations, and development practices and processes have relied on that status. But the explosion in demand for connectivity now sees non-critical systems such as entertainment systems sharing the same communications infrastructure as steering, braking, and control systems. These changes bring the potential for safety … Read more

How to design a battery management system

Battery-powered applications have become commonplace over the last decade, and such devices require a certain level of protection to ensure safe usage. The battery management system (BMS) monitors the battery and possible fault conditions, preventing the battery from situations in which it can degrade, fade in capacity, or even potentially harm the user or surrounding … Read more

N-channel trench MOSFETs eases thermal management for wearables

With their low on-resistance, Nexperia’s 12-V and 30-V N-channel trench MOSFETs minimize energy losses and increase efficiency. The 30-V PMCB60XN and PMCB60XNE come in ultra-compact wafer-level DSN1006 (SOT8026) packages, while the 12-V PMCA14UN is housed in a DSN1010 (SOT8007) package. Nexperia reports that the MOSFETs’ RDS(on) is up to 25% better than competing devices. Simplified … Read more

SSD test appliances ensure PCIe 5 compliance

OakGate R300 3U rack-mount and DE200 desktop test appliances offer scalable conformance testing of PCIe Gen 5 solid-state drives (SSDs). The 8-bay systems give engineers the flexibility to interchange all standard SSD connector types and form factors, while the 16-bay expansion enclosures enable the creation of large test configurations. According to OakGate Technology, now part … Read more

CMOS image sensor boasts dual speed streaming

Sony’s IMX675 CMOS image sensor simultaneously outputs full-pixel captured images at 40 fps, as well as high-speed regions of interest. The 5.12-Mpixel, 1/2.8-in. (6.53-mm diagonal) sensor is the first from Sony leveraging dual speed streaming technology. Aimed at security applications, the IMX675 allows a single camera to not only provide comprehensive images of scenes, but … Read more

The start-up transistor works once!

It’s the mid 1990’s and I am a design engineer for a company that designs and manufactures custom measurement systems and high power electronics. Our customers range from experimental fusion reactor operators to electric utilities. One day my boss tells me to join him in the conference room to meet with some people from a … Read more

DSP IPs for radar, lidar and communication processing applications

The DSP IP cores continue to provide more flexible compute options while allowing system-on-chip (SoC) designers to tailor the instruction set, add data types, and implement tightly-integrated interfaces between the DSP and external logic. These IPs are also supported by a comprehensive set of complex math library functions. Take the case of two new DSP … Read more

200-Mpixel image sensor shrinks pixel size

Samsung’s latest 200-Mpixel image sensor, the ISOCELL HP3, touts a pixel size of 0.56 µm, 12% smaller than its predecessor. At 56 µm, Samsung believes the sensor has the industry’s smallest pixels, packing 200 million pixels in a 1/1.4-in. optical format. Further, ISOCELL HP3 can reduce camera module surface area by up to 20%, allowing … Read more

Mixed Signal Oscilloscope easily goes from bench to field

The 2 Series mixed signal oscilloscope (MSO) from Tektronix provides benchtop performance, yet is small enough to fit in a backpack. Weighing less than 4 pounds, the tablet-like oscilloscope is just 1.5 in. thick and has a 10.1-in. TFT display with a capacitive touchscreen. An optional battery pack supplies up to eight hours of power … Read more
