The RE01 Group uses Renesas' innovative SOTB™ process technology and realizes both ultra-low active current and ultra-low standby current, and high-speed operation (maximum 64MHz) at low voltage (1.62V), which is impossible with a conventional bulk transistor, and is an embedded controller that can operate by energy harvesting. It is equipped with an energy harvesting control circuit, ultra-low power consumption 14-bit ADC (approx. 4uA), flash (rewrite at less than 1mA), parallel MIP-LCD interface, 2D graphics, UI for clock movement, and security functions such as a trusted secure IP. It also has large-capacity 1.5MB flash and 256KB SRAM that can handle data logging and firmware updates. Therefore, the RE01 Group is suitable for wearable devices, home appliances, building automation, industrial sensor devices, smart locks, asset trackers, and other applications.

Hardware Design Support
|IBIS/BSDL||IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board. BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.|
