Hello Renesas team
Maybe it's a stupid question
I found RAM operation stopped during standby mode in the table of specification, but I think data stored in Ram will be retained.
Is RAM data retained during standby function operation(Halt, Stop, SNOOZE) of MCU and after wakeup?
thanks
Which device are you inquiring about?
sorry. it is rl78/F23 mcu.
In STOP mode RAM data are retained as long as Vdd is above VDDDR and no power-on-reset is triggered:
In HALT and SNOOZE mode the memory retention voltage is the same as the supply voltage for the guaranteed range for operation.
