Type
Function
GND
6, 34
GND
Digital ground pin for IO pins and digital circuitry.
VCC_IO
7
3.3V or 5V I/O supply voltage pin for all digital pins.
VSA
30
Analog supply voltage for 5V regulator – typically supplied with
driver supply voltage. An additional 100nF capacitor to GND (GND
plane) is recommended for best performance.
GNDA
31
GND
Analog GND. Tie to GND plane.
5VOUT
32
Output of internal 5V regulator. Attach 2.2µF or larger ceramic
capacitor to GNDA near to pin for best performance. Use to supply
VCC of chip.
