Renesas RE01 Group R7F0E01182xxx embedded controller

Renesas Electronics’ latest embedded controller is an ultralow power consumption device based on the company’s silicon-on-thin-buried-oxide (SOTB) process technology and built around the Arm Cortex-M0+ core, with maximum operating frequency of 64 MHz.

The RE01 Group R7F0E01182xxx variant features 256 KB flash memory variant with 128 KB SRAM. With a minimum 3.16 x 2.88 mm WLBGA package size, the embedded controller is optimised for use in 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 product features current consumption as low as 25 μA/MHz during operation and 400 nA during standby through the use of SOTB process technology. Users can further reduce operation current consumption to 12 μA/MHz by using the company’s ultralow Iq ISL9123 as an external step-down regulator.

With ultralow power consumption, the embedded controllers can 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 small current output or by energy harvesting devices.
