Power Supply
The baseband IC is supplied with four distinct supply voltages:
VDD18, the nominal 1.8V supply voltage for the core, the RF-I/O pins, the memory interface
and the test pins and all GPIO-pins not mentioned in next item.
VDDIO, the variable supply voltage within 1.8V to 3.6V for following GPIO-pins: P1, P2, P8,
P12, P14, P16, P17, P18, P19, P20, P21, P23, P24, P25, P26, P27 and P29. In input mode,
these pins are 5V input tolerant.
VDD_USB, the power supply of the USB pins: USB_DM and USB_DP.
VBAT18 to supply the backup domain: RTC, backup SRAM and the pins NSLEEP, NSHDN,
LDO_EN, VBAT18, P9/EXTIN0, P13/EXTINT1, P22/RXD2 and P31/RXD1 and the 32kHz
oscillator. In input mode, the four GPIO-pins are 5V input tolerant.
Figure 4-1, Figure 4-2 and Figure 4-3 show examples of the wiring of ATR0621 power supply.
