LDRA tool suite implementation is now so small and fast that test environment mirrors the speed and functionality of application execution
LDRA has optimized the LDRA tool suite target implementation to deliver the same comprehensive software test and verification capabilities with a 60 percent smaller on-target footprint.
The reduced footprint minimizes test overhead significantly so that time-critical dependencies can now be properly traced. Instrumentation overhead no longer interferes with the real-time execution on the target.
New Verification Method Reduces Overhead to 5-10 Times Less than Conventional Approaches
Surface-Mount Precision Thin Film Chip Resistors on Aluminum Nitride Substrates Deliver Power Ratings to 6W
Vishay Intertechnology introduced a new series of high-power, surface-mount precision thin film chip resistors. Built on aluminum nitride substrates, PCAN series devices offer power ratings of 2 W and 6 W in compact 1206 and 2512 case sizes, respectively.
The aluminum nitride substrates of the Vishay Dale Thin Film resistors released today feature enlarged backside terminations to reduce the thermal resistance between the topside resistor layer and the solder joint on the end user’s circuit assembly. As a result, the devices provide four times the power handling capability of commercial chip resistors, making them ideal for use in power supplies for industrial, telecommunications, test and measurement, medical, and military and aerospace equipment and instrumentation.
Airbiquity announced the deployment of two “best-of-breed” content providers to serve the European connected car market. They are Eurosport.com, the leading sports news and information provider in Europe, and NAVX, the leading fuel station location, pricing, parking, and EV charge point information provider.
Both deployments reflect the growing importance of the connected car market, driver demand for locally relevant in-vehicle infotainment, and the continued regionalization of the Airbiquity smartphone app and cloud content portfolio made available to Airbiquity’s automotive OEM customers.
Linear Technology UL60950-Recognized 2kVAC, 2.5W Isolated µModule Converter in 9mm x 15mm x 4.92mm BGA
July 30, 2014 by John Day
Linear Technology Corporation introduced the LTM8046, a 2.5W output DC/DC µModule® (micromodule) converter with 2kVAC galvanic isolation (production tested to 3kVDC) in a 9mm x 15mm x 4.92mm ball grid array (BGA) package.
A minimum creepage distance of 4.3mm on the package exterior supports operation at a working voltage up to 400VRMS in a pollution degree 2 environment.*
The isolated transformer, control circuitry, power switches, and a modest amount of input and output capacitance are encased in the BGA package. The UL60950 recognized (file# 464570) LTM8046, combined with three 1206 case size or smaller ceramic capacitors and one 0603 size resistor, comprise a highly compact solution for isolated transportation and other applications.
ERM Advanced Telematics, a manufacturer of tracking and telematics solutions, is marketing an analog fuel level reader called eFuel that can transmit refueling and fuel theft events via its StarLink family of tracking devices, using ERM’s proprietary eNet technology.
The eFuel converts the original float sensor data into clear and simple information and offers fuel level changes alerts also during IGNITION OFF/ON thanks to its specially designed pull-up mechanisms. The eFuel offers fast dry calibration, so there is no need to empty the fuel tank. Total calibration takes up to 30 minutes.
Altium Limited announced a new addition to its TASKING C compiler solutions for automotive application development, providing support for the RH850 architecture from Renesas Electronics.
The RH850 is the latest automotive microcontroller family from Renesas to offer high performance balanced with very low power consumption over a wide and scalable range of products. This family provides rich functional safety and embedded security features needed for new and advanced automotive applications. It offers a range of CPU core structures (single, multiple, lock-step and combination thereof) to support high performance and/or high reliability requirements.
CD-adapco announced the completion of its development project targeting the automotive and lithium ion battery industries, enabling faster design and development of advanced electric drive vehicle power systems.
The project, which began in August 2011, is co-funded by the Vehicle Technologies Office in the U.S. Department of Energy (DOE) and managed by DOE’s National Renewable Energy Laboratory (NREL). The project is part of the competitive Computer Aided Engineering of electric drive Batteries (CAEBAT) activity launched by DOE in 2010. The initial award of the project was reported on July 7(th), 2011 and the project team included CD-adapco, Battery Design Inc., Johnson Controls Inc., and A123.
Based on Texas Instrument’s 1 GHz Sitara™AM335x ARM Cortex-A8, the VAR-SOM-AM3_V2 targets automotive applications in addition to those in other industries. Connectivity features in the new version are based on TI’s FCC/CE certified dual band Wi-Fi 802.11 a/b/g/n with optional MIMO and Bluetooth 4.0 / BLE that can achieve effective bit rates of 100 Mbps, together with extended wireless range.
TRW Automotive Holdings Corp. launched its latest-generation Electric Park Brake (EPB) technology with three major Japanese based vehicle manufacturers and will begin production with a fourth automaker in the near future.
The EPB system functions as a conventional hydraulic brake for standard service brake applications, and as an electric brake for parking and emergency braking.
“Because EPB is electronically rather than mechanically controlled it can work with a variety of vehicle systems and sensors,” said Peter Lake, executive vice president, sales for TRW. “As an example, in the U.S. following NHTSA’s recent FMVSS 111 amendment that will require rear backup cameras, an EPB system could be integrated with the video signal and automatically brake the vehicle if a potential issue is detected.”

Flexpoint Sensor Systems, Inc. received notice that an automobile maker has completed testing of a horn switch system incorporating its Bend sensor technology. The system functioned properly and the product can now be designated for incorporation into future vehicle programs.
It is expected that as the horn switch units are integrated into the first available program, the sensor will be expanded to integrate control switches onto the horn pad. Current airbag configurations have limited the design flexibility of horn switches, which are generally placed on the sides of the center steering column to avoid interference with the driver’s side air bag.
