A panel of experts at ARM TechCon predicted that chips need to get a lot cheaper to really make the Internet of Things thrive. EE Times reports future applications will probably need fully functional, energy-efficient SoCs with a cost of less than 50 cents. Furthermore, the power consumption of these chips will need to go down massively.
Today’s SRAM and flash memories, Bluetooth interfaces and sensors consume too much power to serve volume IoT nodes in 2027, panelists said. They sketched out a few possibilities for what may replace them.
Ideally, a 2027 end node SoC will consume just 10 microwatts/MHz and send and transmit data on a radio drawing only 1 or 2 milliwatts, said Jason Hillyard, a director of software in ARM’s wireless group. His “slideware SoC” used a new architecture built of subthreshold circuits suited for its energy harvesting power source.
