Q&A With Jeff Blecher, Agero Senior VP, Strategy.
Agero is working with the AgeLab and the New England University Transportation Center to study the risks and benefits associated with advanced driver assistance systems (ADAS).
Are automakers designing features that assume a driver is paying attention?
Automakers are taking different paths regarding driver attention – some are using eye tracking technologies, some are requiring you to keep your hands on the steering wheel, and others are relying on the driver to mostly self-monitor.
The MIT AgeLab, the New England University Transportation Center and Agero are working together to assess the safety relevant benefits of Advanced Driver Assistance Systems (ADAS) and the risks involved with in-vehicle demands.
The collaboration will draw initially upon the automotive insurance industry and eventually involve automotive manufacturers, suppliers, and the consumer electronics industry. It will attempt to:
• Characterize the relative safety benefits of various ADAS in different operating contexts
• Develop objective data on the utilization of these systems
• Establish normative and environmentally valid characterizations of “safety critical events”
• Collect the most up-to-date set of data on the ecosystem of electronics usage and related distractions in the vehicle

FLEXConnect.IVI Improves IVI User Experience and
FLEXConnect.ANC Reduces In-Vehicle Noise
Mitsubishi Electric announced two new FLEXConnect™ In-Vehicle Infotainment (IVI) systems. FLEXConnect.IVI provides a three-screen user interface that is both intuitive and cost effective, and FLEXConnect.ANC is an Active Noise Control (ANC) system that cancels less predictable and harmonically unrelated road sounds.
The FLEXConnect architecture is a family of systems that extend typical infotainment uses by allowing easy access across multiple devices over Ethernet and Wi-Fi. Last year Mitsubishi Electric introduced the FLEXConnect series with FLEXConnect.RSE, (Rear Seat Entertainment). FLEXConnect.RSE features two rear-seat screens that allow the user to stream multiple contents per individual preferences while operating as independent units controlled through the Ethernet AVB architecture.
Analog Devices 4-channel, 24-GHz Receiver Downconverter MMIC Combines Low-Noise, High Linearity and Low Power Consumption.
Analog Devices, Inc. introduced the ADF5904, a highly integrated, 4-channel, 24-GHz receiver downconverter MMIC that combines low-noise performance, high linearity and low-power consumption.
The ADF5904 is designed for multi-channel receiver, high-frequency applications that use digital beam forming, such as automotive ADAS, microwave radar sensors, and industrial radar systems – environments where energy efficiency is becoming a more important system-level design consideration.
The ADF5904 24-GHz receiver enables these and other sensor applications by offering best-in-class receive sensitivity, according to the company, while using less overall power than competing RF technologies.
Linear Technology Corporation announces the LT8495, a current mode, fixed frequency SEPIC/boost DC/DC converter with an internal 2A, 70V switch.
Ultralow quiescent current of only 9µA makes it ideal for always on automotive systems, and its integrated power-on reset (POR) and watchdog timer offer enhanced system reliability required in automotive and industrial applications.
The LT8495 starts up from an input voltage range of 2.5V to 32V, and once running, it operates from inputs of 1V to 60V, making it suitable for applications with input sources ranging from a single-cell Li-Ion to automotive inputs.

Silicon Storage Technology and GLOBALFOUNDRIES Announce Qualification of Automotive Grade 55nm Embedded Flash Memory Technology
Microchip Technology Inc., through its Silicon Storage Technology (SST) subsidiary, and GLOBALFOUNDRIES, a leading provider of advanced semiconductor manufacturing technology, announced the full qualification and availability of SST’s 55nm embedded SuperFlash® non-volatile memory (NVM) on GLOBALFOUNDRIES’ 55nm Low Power Extended (LPx)/ RF enabled platform.
The qualification of GLOBALFOUNDRIES’ 55nm, split-gate-cell SuperFlash technology-based process was performed according to JEDEC standards. This process technology also met the requirements of AEC-Q100 Grade 1 qualification with an ambient temperature range of -40°C to 125°C, and demonstrated endurance of 100K program/erase cycles with more than 20 years of data retention at 150°C.
Most battery and plug-in hybrid electric vehicle (PHEV) manufacturers in Europe and the United States (US) have been adopting onboard chargers with a power output between 3 to 3.7 kilowatts (kW). Now, according to Frost & Sullivan, EV manufacturers are moving towards onboard chargers with a power output greater than 6.6 kW to reduce charging time.
Not So Fast
While high-end PHEVs are contributing to this trend, lower-end models in this segment are still using 3.7 kW onboard chargers. Consequently, onboard chargers with power ratings between 3 to 3.7 kW are expected to remain dominant, accounting for 62 percent of sales even in 2020.

At the Embedded Vision Alliance Summit 2015 in Santa Clara, CogniVue Corporation said its new APEX Processing Core, Opus, is at the center of an intense battle for Advanced Driver Assistance Systems (ADAS) market share as challengers to Mobileye, the current market share leader, line up to capture business for next-generation ADAS systems.
Next-generation ADAS systems will provide a range of critical new autonomous driving functions requiring orders of magnitude more performance than previous offerings. CogniVue said its Opus APEX core offers dramatic advances in performance per power at a critical time in this disruption of the ADAS market.
Seiko Instruments Releases Selectable Mode Watchdog Timer with Reset Function for Automotive Applications
May 11, 2015 by John Day
Seiko Instruments Inc. (SII) released the new S-19400/19401 series watchdog timer with reset function featuring selectable window or timeout modes, current consumption of 3.8µA, and high temperature operation up to 125°C.
Modern automobiles incorporate from 50 to 100 microcontrollers including many that have to be continuously monitored for vehicle safety or performance reasons.
The new SII watchdog timers are optimized for use in automotive microcontroller monitoring and automotive ECUs that require precise fault detection. They monitor periodic signals from microcontrollers and signal any abnormal operation.
