Pin Information
This chapter describes, lists, and illustrates the CY8C24794 PSoC device pins and pinout configuration.
1.1
56-Pin Part Pinout
The CY8C24794 PSoC device is available in a 56-pin package which is listed and illustrated in the following table. Every port pin
(labeled with a “P”) is capable of Digital IO. However, Vss and Vdd are not capable of Digital IO.
