Eta Compute Debuts with Worlds Lowest Power Microcontroller IP Targeting Energy Harvesting Segment

Eta Compute has announced its flagship solution, EtaCore, a low power microcontroller IP, which operates on the smallest energy harvesting supplies without compromising functionality or performance. Operating in deep subthreshold (as low as 0.25 V) where conventional approaches fail, the company’s low-power system-on-a-chip (SoC) and microcontroller intellectual property is expected to be the foundation for a wide range of applications that support a more intelligent IoT.

Enabling large-scale IoT deployment requires low-power solutions for energy – constrained sensors and devices – without compromising on functionality and performance, said Lakshmi Mandyam, general manager, automotive, IoT and embedded Business Segment Group, ARM. Eta Computes ultra-low power ARMCortex-M3 processor-based device will enable our ecosystem to get to market faster, with efficient devices powered by energy harvesting and small coin cell batteries.

By 2020, it is estimated that there will be 24 billion devices connected by the IoT. Deploying these always-on, always aware devices require a disruptive solution that reduces overall power consumption to enable perpetual operation. Eta Computes unique low-power design methodology, IP and custom designs operate within wide variations of temperature, process, voltage, and power supply. Eta Compute’s IP operates in deep subthreshold and includes an ARM Cortex-M3 core that operates from 0.25 to 1.2 volts. The result is smaller products with fewer components operating robustly at voltages as low as 0.25 V (90LP process).

Eta Compute offers the only commercially available self-timed technology supporting dynamic voltage scaling that is insensitive to process variations, inaccurate device models and path delay variations. For customers that develop complete SoC products, Eta Compute has added additional low voltage supporting IP such as RTC, AES, and DSP. In addition, an analog-to-digital converter (ADC) sensor interface consumes less than 3uW and an efficient power management supports dynamic voltage scaling down to 0.25V with greater than 80 percent efficiency are both available.

  • PMIC for Dynamic Voltage Scaling delivering 0.2 V to 1.5 V with >80 percent efficiency
  • 12b 200k Sample/sec SAR ADC with power consumption below 3 uW
  • Real time clock Digital IP with power consumption below 15 nW
  • Low Power Embedded DSP optimized for audio applications
  • 128-bit block cipher AES that supports key sizes 128, 192 and 256-bits

A compact, low-power sensor node is the key enabler for the deployment of billions of devices in the IoT, said Lip Bu Tan, Chairman of Walden International and an investor in Eta Compute. The team at Eta Compute has a history of successful low-power computing products and has delivered a truly compelling solution for IoT.
