ADVANCED COMMUNICATIONS & SENSING
VANA, VDIG
The SX8634 has on-chip regulators for internal use (pins VANA and VDIG).
VANA and VDIG have protection to VDD and to GND.
The output of the regulators needs to be de-coupled with a small 100nF capacitor to ground.
Figure 44 shows a simplified diagram of the VANA and VDIG pin.
4.5 General purpose IO pins
The SX8634 has 8 General purpose input/output (GPIO) pins.
All the GPIO pins have protection to VDD and GND.
The GPIO pins can be configured as GPI, GPO or GPP.
Figure 45 shows a simplified diagram of the GPIO pins.
