Discussion - MCU / RTC on FT90x revision C
« on: April 12, 2020, 08:01:33 AM »
We would like to use a supercap to power the VBAT pin when the CPU FT90x C is without power. I need the characteristics of the VBAT pin and the impedance when the chip is turned off as minimum maximum voltage and current. Can you help me? Do you have an application note for this?
Many thanks
