Current Consumption in Deep Sleep LSI

In this example: https://github.com/IOsetting/py32f0-template/blob/main/Examples/PY32F002B/LL/LPTIM/LPTIM_LSI_DeepStop_WakeUp/main.c

/**

  * Connections

  *  VCC      ---> 3.3V
  *  GND      ---> GND

  * - MCU enters deep stop mode after 3 seconds,
  * - LED blinks every 5 seconds (In low voltage LSI becomes slower and slower, the

  * - Current consumption is around 0.6uA in deep stop mode
  */

Its description said it consumes around 0.6uA in deep stop mode.

Is this figure real? As per its datasheet, it should be around 5ua or above.

I don't have Py32F002B to test, I have only F002A.

002B is a different series, low power but less on-chip resources.

It's real but not officially guaranteed. In 002B's datasheet it only lists the stop mode. Deep stop mode is a feature of PY32L020, but I doubt they are the same chip.

Glad to know that PY32f002B is much more power efficient than others
