Renesas employ smart MCU power management techniques which include autonomous peripheral operation with DMA. The solution is to place the MCU in the lowest possible power mode whilst the peripherals are allowed to perform functions. In this presentation and tools demonstration, Renesas will show how to enable lowest system power using there RL78 MCU smart peripheral techniques.To extend the idea, individual peripherals could be given more functions and even reduce DMA operations. For example A/D converter with compare functionality so that the result register need not wake up the CPU if the result is within or outside the threshold limits. Similarly a serial interface could be checked for a valid and desired data and if that is not received then the CPU could be sleep mode. Renesas extends this idea of implementing the technique to other peripherals within the MCU to make them smarter.
