HI TI AM335x and Power IC Team.
We have a customer who would like to use the traditional RTC Power Solution for their AM3358 Internal RTC activation.
They're focusing on the 1st connection topology which required external regulator.
Can you please clarify how to make right connection and pin handling below ?
- Add an external regulator to connect with VDDS_RTC_1.8V domain with coin-cell battery.
- VDDS_RTC/RTC_KALDO_ENn : Cap(0.1uF+0.1uF) to GND
- CAP_VDD_RTC : tie to 1.1V rail
- RTC_PWRONRSTn : GND
- PMIC_POWER_EN : N.C
- EXT_WAKEUP0 : GND
