Smart meter transceiver works on dual bands
Atmel Corporation, a global leader in microcontroller (MCU) and touch solutions, announced a new family of wireless transceivers. Atmel’s AT86RF215, the first sampling device, is the industry’s first dual-band sub-1GHz / 2.4GHz transceiver compliant to IEEE 802.15.4g-2012 and ETSI TS 102 887-1. Expanding the Atmel SMART metering portfolio, the new devices include the AT86RF215M, a […]
Choosing, using and designing oscillators
Most electronics today have oscillators in them. Digital circuitry needs a clock. Radio frequency signals require an oscillator or clock. Some analog circuitry also needs a clock or oscillating signal source. If you are using a microcontroller then it might have a built-in clock, although it may not be accurate enough, depending on your application, […]
Low Power Conversion for Energy Harvesting
by Tony Armstrong, Director of Product Marketing, Linear Technology Corporation There is plenty of ambient energy in the world around us and the conventional approach for energy harvesting has been through solar panels and wind generators. However, new harvesting tools allow us to produce electrical energy from a wide variety of ambient sources. Furthermore, it is not the […]
Terminal block and header target LED designs
New additions to Phoenix Contact’s PTSM family give LED designers more options. The new single-pole PTSM terminal block and the vertical header are ideal for space-critical applications, and a new through-board header expands connection options. Like the original PTSM terminal blocks, the single-pole PTSM features push-in termination technology for quick wire connection. The 2.5 centerline […]
