Full question:
What is the voltage generated by the buck converter for core and system memory in the Apollo1 and Apollo2 MCUs?
Answer(s):
For Apollo1:
VOUT1 rail is used for the core and is 750 mV - 875 mV.
VOUT2 rail is used for SRAM and is 1.10 V - 1.280 V.
For Apollo2:
VDDC rail is used for the core and is 640 mV - 700 mV.
VDDF rail is used for SRAM and Flash Cache and is 880 mV - 950 mV.
Flash cells operate from the Vbat rail (1.8 V - 3.6 V).
