Energy Micro løfter sløret for banebrydende radio familie
Energy Micro annoncerer flere detaljer om en radio produktfamilie, som ifølge firmaet kan reducere energiforbruget med en faktor fire (in english).
Energy Micro has announced advance details of its forthcoming energy friendly radio (EFR) product family. Complementing the companys EFM32 Gecko microcontrollers, EFR4D Draco high performance radio solutions will consume only 25% of the energy of competing products, the company claims. Based on an ARM Cortex-M0 core, Draco system-on-chip (SoC) radios will achieve receive and transmit current consumption as low as 5mA and 6mA respectively.
To maximise design flexibility, the EFR4D Draco product family will be offering users 3 alternative and cost effective radio device implementations: transceiver only, supported by EFM32 for protocol stack and user application; combined transceiver and protocol stack, supported by EFM32 for user application; and complete SoC solution, integrating transceiver, protocol stack and user application in a single EFR4D. The first transceiver only and SoC products are scheduled to be sampling during Q42011. Pricing will start at $1.1 each in 100k quantities.
The radio performance of the EFR4D products will also be higher than existing alternatives, with a maximum output power of +17dBm at 868MHz for example, receive sensitivity of typically -121dbm, FSK 1.2kbps and high receiver selectivity, blocking and image rejection capability.
EFR4D will also be handling more frequency bands and radio protocols than competing products. The products will span the complete RF spectrum between 167MHz and 2500MHz and will support the industrys broadest range of radio protocols, including IEEE 802.15.4, Bluetooth LE and Wireless M-Bus. EFR will also readily suit customers proprietary protocols.
Energy Micro President and CEO, Geir Frre says:
- In the pursuit of the lowest possible energy consumption, designers of energy sensitive products relying on wireless connectivity need to consider the overheads presented by both the processor core and the RF transceiver both have a significant impact on energy budgets. We have already proven, with our Gecko product family, that we can create the worlds most energy friendly microcontrollers, so it makes perfect sense that we also now turn our attention to creating the worlds most energy friendly radio transceivers and SoCs. Draco will combine a state-of-the art RF transceiver with a technology-leading microcontroller to help designers achieve a 4 times longer battery life.
Before founding Energy Micro in 2007, Frre led Chipcons development as Co-founder, President and CEO, from its origins in 1996 as a design house to becoming the market leader in low-power RF solutions 10 years later. Chipcon was acquired by Texas Instruments in January 2006.
