Renesas RE01-256K

Ultra low power microcontroller with the leading EEMBC ULPMark™ benchmark of 705

The RE01-256K offers a unique combination of high performance, low voltage operation, and extremely low active and standby currents making the RE01-256K ideal for a wide range of IoT sensor applications. The RE01-256K has a high ratio of Flash/SRAM with 256 Kbytes of ultra low power flash memory and 128 Kbytes of SRAM offering execution from flash with current consumption as low as 12 uA/MHz. These levels of performance allow the RE01 to achieve market-leading levels of performance in the independently verified EEMBC ULP benchmarks.
