SOTB process delivers low-power energy harvesting controller

Renesas has developed an energy-harvesting embedded controller that can eliminate batteries in IoT devices. Based on Renesas’ SOTB (silicon–on–thin–buried–oxide) technology it uses a 32-bit, Arm Cortex-based embedded controller capable of operating up to 64 MHz while consuming 20 μA/MHz active current and 150 nA deep standby current. The R7F0E is a configurable Energy Harvest Controller (EHC) function which enables direct connection to many different types ...
