ATR0630 [Preliminary]
The ATR0630 is supplied with six distinct supply voltages:
• The power supplies for the RF part (VCC1, VCC2, VBP) within 2.7V to 3.3V.
• VDIG, the 1.8V supply of the digital pins of the RF part (SIGHI, SIGLO and CLK23). VDIG
• VDD18, the nominal 1.8V supply voltage for the core, the I/O pins, the memory interface and
• VDDIO, the variable supply voltage within 1.8V to 3.6V for the following GPIO pins: P1, P2,
• 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,
should be connected to VDD18.
the test pins and all GPIO pins not mentioned in next item.
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.
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.
