Pinouts
The PSoC CY8C23X33 is available in 32-pin QFN and 28-pin SSOP packages. Every port pin (labeled with a “P”), except for Vss and
Vdd in the following table and figure, is capable of Digital IO.
32-Pin Part Pinout
Note
4. Even though P3[0] is an odd port, it resides on the left side of the pinout.
