Datasheet

Descriptions of the Pin functions are as follows:

VDDD

VDDA

VSSA:

Analog ground pin where package pins allow; shorted to VSS otherwise

VSS

: Ground pin.

VCCD

: Regulated Digital supply (1.8 V ±5%).

Port Pins can all be used as LCD Commons, LCD Segment drivers, or CSD sense and shield pins can be connected to AMUXBUS A or B or can all be used as GPIO pins

that can be driven by firmware or DSI signals.

The following packages are supported: 48-pin TQFP, 44-pin TQFP, 40-pin QFN, and 28-pin SSOP.
