• Radar Scope Eta Compute Eta Compute was founded in 2015 to develop and license the world’s lowest power SoC IP for energy-constrained sensors and devices for the IoT. Eta has raised $3.5 million in seed funding and does not have plans to raise ad¬ditional capital as of this writing. The company has 20 employees. Eta Compute claims to offer the only commercially available self-timed technology supporting dynamic voltage scaling (DVS) that is insensitive to process vari¬ations, inaccurate device models and path delay variations. Eta’s low-power design methodology, IP and custom designs operate within wide variations of tem¬perature, process, voltage, and power supply. Operating in deep-subthreshold (as low as 0.25V), the company’s low-power SoC and microcontroller IP improve power efficiency by 10X without compromising functionality or performance, enabling extremely efficient always-on and always aware processing. Eta believes it offers the only viable solution that can consume < 5uA from small coin cells and energy harvesting applications.

  • To get to deep sub-threshold voltages – and therefore extreme low power – IP licensor and design services company Eta Compute Inc. (Westlake Village, Calif.) has turned to asynchronous logic. Eta Compute, a well-connected startup founded in 2015 and with links to Cadence Design Systems Inc., came out of stealth mode recently claiming it could offer Cortex-M3 cores that consume as little as 2 microwatts (see Startup claims lowest power microcontroller with 0.25V operation). Such low power makes battery-operated sensor nodes with life times of months or even years a possibility, the company claims.

  • Eta Compute Inc. (Westlake Village, Calif.), a startup IP licensor and design services company founded in 2015, claims to have developed the world's lowest power microcontroller IP with a Cortex-M3 processor core that operates down to 0.25V. This is the thought to lowest operational voltage for logic circuitry and well in to the sub-threshold voltage regime of transistor action. Eta Compute has measured data for the Cortex-M3 from ARM in 90nm 90LP process and as the voltage scale from 0.25V to 1.2V the maximum clock frequency scales from 250kHz to 90MHz, the company said by way of email correspondence. The company's low-power system-on-a-chip (SoC) and microcontroller intellectual property is intended to operate in energy harvesting regimes and support autonomous Internet of Things deployments.

  • A continuing challenge for large scale deployment of IoT devices is the need to minimize service/cost by extending battery life to decades. At these lifetimes, devices become effectively disposable (OK – a new recycling challenge) and maintenance may amount to no more than replacing a dead unit with a new unit. Getting to these levels requires effort to manage dynamic, leakage and sensor power consumption. Managing leakage has been covered in many articles on FinFET and FDSOI technologies and discussions on aggressive power switching, though this challenge is not as acute in legacy processes. I wrote recently about advances in managing sensor power where at least for some types of sensing, standby power can be reduced to zero.

  • Design Reuse

    Eta Compute, the company that removes power as an obstacle for the infinite Internet of Things (IoT), announced its flagship solution, EtaCore™, the world’s lowest power microcontroller IP, which operates on the smallest energy harvesting supplies without compromising functionality or performance.
