Mentor Graphics Extends Nucleus RTOS; Targets Next-Generation Applications for Embedded Devices

August 20, 2014  by  

Mentor Graphics Corporation Nucleus with Multicore Framework
Mentor Graphics Corporation announced a new version of the Mentor® Embedded Nucleus® real time operating system (RTOS) targeting high-performance, next-generation applications for connected embedded devices.

The Nucleus RTOS process model is expanded to include ARM® Cortex® M- based cores. For the first time, software developers can use a single embedded operating system to increase system reliability through memory partitioning for the entire spectrum of ARM cores, facilitating code reuse across an entire product family comprising low-end to high-end devices.

New in this release is a multicore framework to manage inter-process communication (IPC) and processor life cycle for complex heterogeneous system-on-chip (SoC) and enhanced Nucleus RTOS graphics capabilities with Imagination and Vivante GPU support.

To complement its brushless direct current (BLDC) pre-driver portfolio and address conventional DC motor applications, Melexis introduces the MLX83100 N-FET pre-driver IC.

Offered in a compact 28-pin package, with four digital inputs, this pre-driver IC provides a very flexible, inexpensive and space-saving solution for high current N-FET DC motors.

Though BLDC motors are now becoming increasingly commonplace, DC motors are still more cost effective in a broad spectrum of application areas, especially where the motor is not continuously running.

By Barrett Kalellis

For the past decade, car manufacturers and their suppliers have given a lot of consideration to human-machine interface (HMI) factors in the design of auto interiors, particularly with respect to various controls that drivers need to access during vehicle operation.

This trend is gathering momentum, as designers try to integrate ever more sophisticated HVAC, navigation and infotainment control systems into the cockpit.

Based on customer feedback about a previous console design, German auto supplier Preh used its long-standing innovative and advanced development expertise to premiere a new center console concept with much acclaim at last year’s Frankfurt Motor Show, making new inroads with HMI.

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

July 31, 2014  by  

vishay new aluminum14740427311_de01d4e700_o

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.

UL60950 Recognized 2kVAC, 2.5W Isolated µModule Converter

 

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.
