Freescale Semiconductor is now offering alpha samples of its Kinetis L series, the industry’s first microcontrollers (MCUs) built on the ARM® Cortex™-M0+ processor. New 32-bit MCUs designed to transform consumer and industrial applications currently using legacy 8- and 16-bit architectures   As machine-to-machine communication expands and network connectivity becomes ubiquitous, many of today’s standalone, entry-level applications will require more intelligence and functionality. With the Kinetis L series, Freescale provides the ideal opportunity for users of [...]

  Vishay Intertechnology, Inc. has  introduced a new series of surface-mount multilayer ceramic chip capacitors (MLCCs) offering high self-resonance, a high Q factor of ? 2000, and a low dissipation factor of ? 0.05 % for operation in high-frequency commercial applications.   With their low dissipation factor, devices in the VJ HIFREQ series are optimized for filter and matching networks, and amplifier and DC blocking circuits. The MLCCs reduce signal loss and energy consumption in power amplifier [...]

Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, today announced the availability of three new super-junction metal-oxide-semiconductor field-effect-transistors (Super Junction MOSFETs) featuring figure of merit: on-state resistance x gate change in a 600 V power semiconductor device suitable for high-speed motor drives, DC-DC converters, and DC-AC inverter applications. This industry-leading low on-state resistance and low gate charge combination benchmark, combined with the fast body diode feature, allow the new RJL60S5DPP, RJL60S5DPK and RJL60S5DPE [...]

Project: It is not hard to make gas sensors for many common gases like CO2, CO, etc. You can also make sensors for Nitrogen, Potassium and Phosphorus to track their quantities in the soil. Just buy the sensor for that gas and attach to an embedded system. Calibrate it and then sync it to a mobile system so that when someone texts a shortcode, he/she can get the amount of that gas in that environment. [...]

The project: The solar inverter performs the conversion of the variable DC output of the PV cells into a clean sinusoidal 50- or 60 Hz current. This product is built around Texas Instrument C2000 or MSP430 Microcontroller series.   The design: Please click the image to zoom     Design Strategy The solar inverter is a critical component in a solar energy system. It performs the conversion of the variable DC output of the Photovoltaic [...]
