Pin Information
This chapter describes, lists, and illustrates the CY8C24x23 PSoC device pins and pinout configurations.
1.1
Pinouts
The CY8C24x23 PSoC device is available in a variety of packages which are listed and illustrated in the following tables. Every port
pin (labeled with a “P”) is capable of Digital IO. However, Vss, Vdd, SMP, and XRES are not capable of Digital IO.
