1) Vbat_IO not connected (resistor R39 is not placed).
Vbat_ADC connected to analog input of MCU (PIN_A0).
2) In test application that I wrote in the beginning I do not use #use delay.
At the rea ... |

All voltages came from a bench power supply: and 5V and 3V.
The schematic drawing of it please find below.
The current I'm measuring in sleep mode is the current that board taking from battery. The ... |

The amount of current in sleep mode (as I wrote previously): 85uA
The amount of current during normal operation mode: 3.71 mA
Vdd = 5V
Vbattery = 3V
No connection to the MCU except ISP (so 19K res ... |

Hi All,
I need to use PIC16F1946 in sleep mode for RTC operation but its power consumption is too high.
Even if I turn MCU to sleep mode immediately after start (no interrupts, no nothing) then ... |
