power draw when stopped STM8Lxxx

[dwood.1]

hi all

i am first time user to ST micros. (8bit motorola mostly)

I am looking at using stm8L132r8 in an ultra low power device, which needs 10year battery life.

the micro will be stopped most of the time, woken by the RTC running from external 32khz xtal once a day.

The data sheet indicates a current draw of < 0.5 uA in this mode (@3v3).

Is this really achievable?
