New Product Introduction

Renesas RE01 1500KB

RE01 1500KB Group - Ultra-low power products with 1.5-Mbyte Flash Memory

Renesas RE01 1500KB MCU - front and back side

The RE01 1500KB product is based on the SOTB™ process technology which realizes ultra-low current consumption in both active and standby mode and high-speed operation (64MHz) at low voltage (1.62V), which is impossible to achieve with conventional bulk silicon processes. The RE01 1500KB product can significantly extend battery life and deliver high performance even for small batteries. In addition, its on-chip energy harvesting controller can extend the battery life further, or completely eliminate a battery to achieve a maintenance-free system. The 1.5MB of on chip flash memory can be used for applications that require the storage of large amounts of data, such as image information, and applications that require remote firmware updates (Over The Air (OTA)) via a wireless or other communications network.

Also available: RE01 256KB

  • Smart home
  • Smart building 
  • Healthcare 
  • Metering 
  • Tracker


Evaluation Kit RE01 1500KB

The Evaluation Kit RE01 1500KB enables evaluation and development by combining energy harvesting with the user's hardware system, which makes semi-permanent battery maintenance for the RE01 1500KB unnecessary.

The kits are now available at Avnet Silica. Contact your local Sales office with the part number RTK70E015DS00000BE.
