A new kind of flash memory is optimized specifically to handle the hostile environment imposed on electronics in vehicular uses. Leland Teschler | Executive Editor You’d have to say the NAND flash memory had an inauspicious beginning. Invented in 1987 by Toshiba, the first NAND flash chip didn’t sell until 1995 when it finally found […]
Tech refresher: Basics of flash, NAND flash, and NOR flash
Flash memory stores information in an array of memory cells made from floating-gate transistors. Each memory cell resembles a standard metal-oxide-semiconductor field-effect transistor (MOSFET) except that the transistor has two gates instead of one. The floating gate (FG) and the control gate (CG) control the current flowing between the source and drain. The CG resembles […]
Newark to offer Infineon MERUS Class D audio amplifiers
Newark, the Development Distributor, announced today the availability of Infineon’s MERUS Class D audio amplifier solutions, which use pioneering multilevel switching technology to increase audio performance and reduce power loss during operation. Infineon’s enhanced design and production standards deliver extreme reliability and stability for the entire product lifetime. The new range offers improved power efficiency, […]
Data injection — Testing autonomous sensors through realistic simulation
Proof that autonomous vehicles are safe to put on the road begins with rigorous models of the sensors that guide them. Holger Krumm | dSPACE GmbH Onboard sensors are critical for autonomous vehicles to navigate the open road, but the real environment is full of obstacles. Everyday interferences such reflective surfaces, whiteout conditions, fog, rain, […]
Portable AWG allows signal-generation for up to 16 channels
A new line of Arbitrary Waveform Generators (AWGs) is based on the LXI instrumentation standard and has been created for engineers and scientists that need to simultaneously generate up to 16 precise electronic signals. Small and compact, the units are candidates for automated testing or remote-control type applications. With six new instruments being released, users […]
Bluetooth and the road to a keyless future
Efforts are underway to let smartphones double as car keys. Erik Peters, Dialog Semiconductor From hands-free calling to tire pressure monitoring systems, Bluetooth has revolutionized the way we interact with our vehicles and how the vehicle itself communicates with other technology systems and services. So, what’s next? Improved internet connectivity and other technological advancements have […]
First implementations of Bluetooth-enabled keyless cars reveal a few bugs
The first production vehicle to employ a Bluetooth (actually a BLE) digital key is Tesla’s Model 3. When the owner approaches carrying his or her smartphone equipped with Bluetooth, Model 3s can be set to unlock their doors and trunk automatically, and starting the Model 3 is as simple as shifting out of Park. Nevertheless, […]
Spectrum co-existence challenges in the fully connected car
High-performance RF bandpass filters may hold the key to autonomous vehicle communication without interference. Ali Bawangaonwala | Qorvo, Inc. Continuing advances in technology are making the autonomous vehicle a practical reality, and there is frequent discussion among technologists about Wi-Fi and 5G as enablers of the connected car. Equally important, but less talked about, are […]
How GMR wheel speed sensors help advance vehicle control and braking systems
Giant magnetoresistance sensors are strong candidates for the high-accuracy wheel-speed sensing necessary in autonomous vehicle systems. Christine Graham | Allegro MicroSystems The purpose of a braking system has evolved from simplistic stopping to critical functions in vehicle safety through highly accurate feedback to traction control (TCS) and advanced driver assistance systems (ADAS). These advances have […]
RF limiters protect sensitive RF receivers up to 40 GHz
A line of broadband, high-power coaxial limiters are designed to help protect sensitive components in the receive chain and other microwave circuits in close proximity to high power signals. The typical applications for these RF limiters include electronic warfare, military communications, instrumentation, fiber optic communication systems, SATCOM, radar, point-to-point wireless, telecom and R&D applications. Pasternack’s […]
