Abstract
The present invention provides a system with an MCU and flash memory and a method for DPD control thereof. A new DPD mode (first DPD mode) is provided by simply adding a power supply pin to the MCU. The power supply pin is coupled to a power supply terminal of the flash memory. In a deep power down mode, the flash memory is configured to be entirely powered down, leading to even lower system power consumption than in a conventional DPD mode (second DPD mode).
