November 26, 2014 by John Day
The single-line, automotive-qualified RClamp0531TQ offers low-clamping voltage performance, an essential requirement for safeguarding the sensitive electronics common in today’s automotive infotainment and telematics systems.
Built on Semtech’s highly differentiated process technologies that achieve the industry’s lowest clamping voltages, the RClamp0531TQ delivers optimal transient protection. This low-clamping voltage protection performance is critical in an automotive industry where maximum ESD protection margin is needed.
Teledyne LeCroy has added new measurement and graphing capabilities to its CAN Flexible Data-Rate (FD) serial trigger and decode solution.
Teledyne LeCroy is the only provider of CAN FD measurement and graphing capabilities, and was the first to provide a trigger and decode solution for CAN FD in June 2014. The new CAN FD trigger and decode solution with measurement and graphing capabilities (CAN FD TDM) enables designers using this new standard to gain unprecedented insight in to their systems, correlating physical layer signals and protocol layer data on a single display while also measuring and plotting bus performance. These tools can be used to measure the time between two CAN or CAN FD messages, or from a message to an analog signal. These measurements can then be extracted to recreate analog waveforms.
Microchip Introduces 5V dsPIC33 “EV” Family for Enhanced Noise Immunity and Robustness in Harsh Environments
Devices Feature Advanced Motor Control, CAN, SENT and Touch Peripherals for Automotive and Other Applications
Microchip Technology announced from the SPS IPC Drives Conference in Germany a new family of 16-bit dsPIC33 Digital Signal Controllers (DSC) with the dsPIC33 “EV” family.
This new family provides 5V operation for improved noise immunity and robustness, ideal for devices operating in harsh environments such as automotive applications.
The dsPIC33EV family is the first dsPIC(®) DSC with Error Correcting Code (ECC) Flash for increased reliability and safety. For safety-critical applications, the dsPIC33EV devices also include CRC, Deadman Timer (DMT), and Windowed Watchdog Timer (WWDT) peripherals as well as a backup system oscillator and certified Class B software.
Symtavision has extended its collaboration with Lauterbach to improve integration between SymTA/S and TraceAnalyzer timing design tools and Lauterbach’s TRACE32® suite of modular microprocessor development tools.
The improved integration will better ensure the safety and reliability of automotive real-time software while also speeding development and reducing costs.
The existing workflow, which enables real-time traces from TRACE32 to be imported and analyzed using Symtavision’s SymTA/S and TraceAnalyzer timing design and analysis tools, has been improved to facilitate better support of rich traces with wait and release behavior, the import of traces with runnable activity within tasks and the ability to import and analyze functional-level traces generated by TRACE32.
dSPACE has released version 4.3 of its AUTOSAR tool SystemDesk®. The software now enables design engineers and software integrators to generate virtual electronic control units (V-ECUs) according to AUTOSAR R4.
SystemDesk is used for the model-based development of ECU software, specifically, for designing the software architecture according to AUTOSAR and generating AUTOSAR-based V-ECUs. It supports the software architecture development process from modeling software components (SWCs) to specifying system-level hardware topology and network communication.
V-ECUs make testing new ECU functions without a hardware prototype fast and easy with the dSPACE virtual validation tool chain.

CSR plc (LSE: CSR; NASDAQ: CSRE) announced two important software releases for the SiRFstarV™ 5ea automotive-grade quad-GNSS location platform. Support has been added for concurrent use of GPS and BeiDou (BDS) satellite constellations, along with major updates to the SiRFDRive® software dead reckoning algorithms.
Together, these upgrades ensure that SiRFstarV™ 5ea offers improved automotive positioning performance meeting the requirements of leading OEMs across the globe. By adding support for China’s BDS constellation to SiRFstarV™ 5ea’s existing GPS and GLONASS capabilities, the new software offers automotive OEMs the flexibility to perform concurrent GPS and GLONASS or GPS and BDS operations.
A Network Enforcement Module (NEM™) designed by Battelle to detect cybersecurity threats in today’s increasingly connected vehicles has successfully completed field trials with several automakers and is ready for commercialization.
The dramatic increase in automotive Internet connectivity to other devices and the Internet provides more entry points to the vehicle’s electronic systems and hackers have taken notice. Vehicles today can have as many as 100 microprocessor-based Electronic Control Units (ECUs) networked together to coordinate and control critical systems such as air bags, infotainment, active cruise, park assist and active steering.
STMicroelectronics’ latest STM32F091 ARM® Cortex®-M0 microcontroller overcomes the resource constraints imposed by similar devices positioned for cost-sensitive applications by providing large on-chip memories and up to eight USARTs that save multiplexing communication ports in applications such as in-car audio or three-phase power metering.
With up to 256Kbytes of Flash on-chip and a 32Kbyte SRAM — enough to implement a Java stack — the STM32F091 can host applications that deliver user experiences normally associated with larger or more expensive devices. All variants, including those in economical 48-pin packages, have at least six USARTs. Three of the USARTs are able to support smartcard, LIN, IrDA, and Modbus modes.
New Microchip 32-bit Microcontroller Series Features Rich Peripheral Set; Large, Scalable Memory Configuration
Microchip Technology announced a new series of its low-cost, high pin count 32-bit PIC32 microcontrollers (MCUs).
By blending the key features of Microchip’s existing PIC32MX1/2 and PIC32MX5 MCU families, this latest PIC32MX1/2/5 MCU series delivers the benefits of a rich peripheral set for a wide range of cost-sensitive applications that require complex code and higher feature integration at a lower cost.
Based on magnetic Circular Vertical Hall (CVH) technology, the A1332 and A1334 devices, with their system-on-chip (SoC) architectures, provide fast output refresh rates and low signal path latency to support a wide variety of demanding automotive and industrial applications.
Both devices are ideal for automotive applications such as electronic power steering (EPS), transmission, motor position, throttle/pedal position, and other systems that require accurate measurement of angles.
