What relations should be kept between the different VDD rails of EFR32 Series 1 for proper operation?
Answer
The following power supply restrictions need to be followed on the EFR32 Series 1 devices:
• VREGVDD must be the highest voltage in the system for EFR32.
• VREGVDD = AVDD
• DVDD <= AVDD
• IOVDD <= AVDD
• RFVDD <= AVDD
• PAVDD <= AVDD
• DVDD > DECOUPLE
These relations above are strongly recommended to be followed for proper operation of EFR32 wireless gecko, and mainly due to the internal ESD diode structures and operation conditions.
