To ensure that VBAT get powered from the backup
battery only when the main power is off, it is
recommended to use two diodes as indicated in the
schematic below.
While firmware is stable and no changes are released often, there are cases where an
update is necessary. We highly recommend making this update feature available on final
designs. The design should provide access to UART RX and TX pins, loader pin and reset
pin.
ALFAT SoC is based on STM32F205RBT6. Consult with STM32F205RBT6 datasheet for
electrical characteristics if needed.
