Ultra-low power embedded controller achieves more

Renesas Electronics has expanded its RE Family lineup of embedded controllers with a new ultra-low power consumption member based on Renesas’ breakthrough silicon-on-thin-buried-oxide ( SOTB) process technology.

Built around the Arm Cortex-M0+ core, the newest member of the RE01 Group lineup is a 256 kilobytes (KB) flash memory variant. Featuring a minimum 3.16x2.88mm WLBGA package size, the new embedded controller is optimized for use in more compact product designs in IoT devices for sensor control. The new embedded controller received a certified EEMBC ULPMark-CoreProfile (CP) score of 705, verifying its world’s top-class energy efficiency. The new embedded controller features current consumption as low as 25 μA/MHz during operation and 400 nA during standby, placing it among the world’s leaders in ultra-low current consumption. Customers can further reduce operation current consumption to 12 μA/MHz by using Renesas’ ultra-low Iq ISL9123 as an external step-down regulator.

The EK-RE01 256 KB Evaluation Kit can be used in combination with user systems to evaluate all peripheral functions, including energy harvesting systems.
