TM4C1294NCPDT: What is current consumption of VBAT pin when MCU is power down. I wish to establish discharge rate from supercap or coin battery (3V0)

Part Number: TM4C1294NCPDT

What is the current consumption of the VBAT pin when MCU is power down while retaining the RTC operation? I wish to establish discharge rate from supercap or coin battery (3V0).

I could not find it in the datasheet.

Hi Richard,

This is listed in the datasheet in the under Current Consumption shown in table 27-63. Refer to the parameter IHIB_RTC. As you can see, the current consumption is about 1.29uA.
