Low-current 32-bit controllers run on harvested energy

Renesas Electronics introduced its RE Family, which encompasses the company’s current and future lineup of energy harvesting embedded controllers. The RE Family is based on Renesas’ proprietary SOTB (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 voltage. The RE01’s 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.

The RE01 family 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 RE01 can operate at voltages as low as 1.62 V and the lineup includes three package versions: a 156-pin WLBGA package, a 144-pin LQFP package, and a 100-pin LQFP package. The RE01 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.

The new RE01 Evaluation Kit includes an evaluation board which features an RE01 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.
