Renesas adds leading power efficiency to its embedded controller RE series
Renesas Electronics recently 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 and built around the Arm® Cortex®-M0+ core. The newest member of the RE01 Group lineup is a 256 kilobytes (KB) flash memory variant in addition to the 1.5 megabytes (MB) flash memory embedded controller, already in mass production. Featuring a minimum 3.16 mm × 2.88 mm WLBGA package size, the new embedded controller is optimized for use in more compact product designs in IoT devices for sensor control, for applications such as smart homes, smart buildings, environmental sensing, structure monitoring, trackers, and wearable devices.
The new embedded controller received a certified EEMBC® ULPMark™-CoreProfile (CP) score of 705, verifying its world’s top-class energy efficiency (Note 1). This high score was achieved through the use of Renesas’ proprietary SOTB process technology, which enables extreme reduction in both active and standby current consumption.
“We are very pleased that the RE Family embedded controller’s ultra-low power consumption was officially certified,” said Hiroto Nitta, Senior Vice President, Head of SoC Business, IoT and Infrastructure Business Unit at Renesas. “We hope that this will lead to a wider adoption of the RE family, expanding the battery life of embedded devices and relieving more customers of their battery maintenance burden.”
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 ISL9123as an external step-down regulator.
With ultra-low power consumption, RE Family embedded controllers can dramatically extend the battery life of embedded devices. They are also capable of high-speed operation in applications that require real-time data processing from multiple sensors, even when powered by compact batteries with very small current output or by energy harvesting devices. Currently available RE Family MCUs with 1.5 MB of flash memory are optimal for applications requiring a large memory capacity, such as image data processing or wireless firmware updating via wireless communication, while the new RE01 Group is optimal for compact devices and IoT devices for sensor control.
ample shipments of the new RE01 embedded controller are available now with mass production scheduled to begin in late July 2020. The reference price for the R7F0E01082CFM in the LQFP package is US $3.33 per 10,000 unit. The EK-RE01 256 KB Evaluation Kit is scheduled for release in late August 2020.
