Renesas a premier supplier of advanced semiconductor solutions, has introduced the RE Family, which encompasses
the company’s current and future line-up of energy harvesting embedded controllers. The RE Family is based on
Renesas’ proprietary™ (Silicon on Thin Buried Oxide) process technology, which dramatically reduces power
consumption in both the active and standby states, eliminating the need for battery replacement or recharging.
Renesas’ energy harvesting devices feature the company’s unique and revolutionary SOTB process technology, which
allows users to simultaneously achieve low active current and low standby current and high-speed operation at low
32-bit CPU core enables users to implement intelligent functions in equipment powered by low levels of harvested
energy through ambient energy such as light, vibration, or fluid flow.
Group of embedded controllers is based on the Arm Cortex®-M0+ core, which can operate at clock frequencies
up to 64 MHz, and provide up to 1.5 MB of low-power flash memory and 256 KB of SRAM. The
can operate at voltages as low as 1.62 V and the line-up includes three package versions: a 156-pin WLBGA package, a
144-pin LQFP package, and a 100-pin LQFP package. The
also includes an energy harvesting control circuit, an ultra-low power 14-bit A/D converter, and a low power circuit that
can rotate, enlarge, or invert graphics data.
These embedded controllers make it possible for applications to perform highly accurate sensing and data judgement by
excluding noise from signal data when they are used as biological monitors or outdoor environmental sensing applications.
By eliminating the need for battery maintenance in a wide range of applications, these embedded controllers will
contribute to the increasingly widespread use of IoT equipment, such as wearable equipment without the inconvenience of
recharging batteries, and sensing applications for homes, buildings, factories and farms, where manual changing or
recharging of batteries is difficult.
Following the mass production of the
Group, the first of the RE Family, the new
Group Evaluation Kit has been launched which allows users working with the
Group of devices to jump start system evaluations for energy harvesting applications.
Evaluation Kit includes an evaluation board which features an
embedded controller, an interface for the energy harvesting device and a rechargeable battery interface. The Kit also
includes an Arduino-compatible interface for easy expansion and evaluation of sensor boards and a Pmod™
connector to expand and evaluate wireless functionality. In addition, there is an ultra-low power Memory in Pixel
(MIP) LCD expansion board so that users can evaluate display functions faster and a Solar panel.
The Kit also contains sample code and application notes that serve as references for power management design that
eliminates the need for battery maintenance, and driver software that supports CMSIS, Arm®’s Cortex Microcontroller
Software Interface Standard. Sample code for ultra-low power A/D converters, digital filter and FFT (fast Fourier
transform) routines, 2D graphics MIP LCD displays, and secure boot and secure firmware update functions for improved
security are available. IAR Embedded Workbench® for Arm which can use the high efficiency IAR C/C++ compiler, and e2
studio (Eclipse-based integrated developmental environment) which can use the free GNU compiler are available as the
With these features, this kit makes it possible to adopt energy harvesting based on
Group devices at the system level and will accelerate the development of equipment that does not require battery
Energy harvesting systems are an essential step toward the goal of a smart and environmentally conscious society. With
SOTB technology as the core, Renesas will continue to develop innovative technologies and solutions that enable the
growth of these systems.

STMicroelectronics are powering the next generation of Industry 4.0 applications with a new vibration-sensing solution optimized to enable smart maintenance of factory equipment. The IIS3DWB is a system-in-package MEMS sensor featuring a 3-axis digital vibration sensor with low noise over an ultra-wide and flat frequency range. The wide bandwidth, low noise, very stable and repeatable sensitivity, together with the capability of operating over an extended temperature range (up to +105 °C), make the device particularly suitable for vibration monitoring in industrial applications.
