The low-power mode for STM8L and ATTINY2313

I used to thinkSTM8Lwould cost less energy thanATTINY. Today I got some time to view the datasheet for these two MCU.

First comes the STM8Ldatasheet:

If we just use low speed oscillator (LSI) in the STM8L, it would only cost 0.9uA when all other components has shutdown.

How about ATTINY? Then comes thedatasheet:

Since we need to enable watch dog timer (WDT) to wakeup, the ATTINY cost typical 4uA in low power mode.

Seems my memory is still correct
