Renesas extended RE family of ultra-low power embedded controllers with world-class energy efficiency ratio

     Renesas Electronics announced the expansion of its RE family of ultra-low-power embedded controllers with the introduction of the Arm® Cortex®-M0+ core based on Renesas' breakthrough SOTBTM (Silicon on Thin Buried Oxide) process. The newest member of the RE01 group is equipped with 256KB of flash memory, which is different from existing products that have been mass-produced and integrated with 1.5MB of flash memory. The new controller is available in a minimum 3.16mm×2.88mm WLBGA package size and is optimized for product design for more compact iot devices for sensor control, suitable for applications such as smart homes, smart buildings, environmental sensing, (building/bridge) structural monitoring, trackers and wearables.

     The new embedded controller has achieved 705 points in the EEMBC® ULPMarkTM-CoreProfile (CP) certification, confirming its leading energy efficiency (Note 1). This high score is achieved thanks to Renesas' unique SOTB process, which greatly reduces operating and standby current consumption.

     "We are very honored to receive official certification for the ultra-low power consumption of the RE family of products, and hope to promote the wider application of the RE family of products, extend the battery life of embedded devices, and reduce the burden of battery maintenance for more customers," said Keito Nikita, senior vice president of Renesas Electronics and head of the SoC Division of the Internet of Things and Infrastructure Business unit.

     The current consumption of the new product can be as low as 25μA/MHz in the working state and as low as 400 nA in the standby state, and its ultra-low power consumption is leading the world. Users can further reduce operating current consumption to 12μA/MHz with the Renesas Ultra Low Iq ISL9123 as an external step-down regulator.

     RE's ultra-low power consumption significantly extends the battery life of embedded devices. They are also suitable for real-time data processing applications that require multiple sensors and can operate at high speeds even when powered by low-current compact batteries or energy harvesting devices. The RE MCUS currently on the market with 1.5 MB of flash memory are suitable for applications that require large storage capacities, such as image data processing or over-the-air firmware updates. The new RE01 product group is ideal for compact devices and iot devices for sensor control.
