8 / 30 page CY8C20234 Document Number: 001-54650 Rev. *E Page 8 of 30 Pinouts This section describes, lists, and illustrates the automotive CY8C20x34 PSoC device pins and pinout configurations. The automotive CY8C20x34 PSoC device is available in the packages listed and shown in the following tables. Every port pin (labeled with a “P”) is capable of digital I/O and can connect to the common analog bus. However, VSS, VDD, and XRES are not capable of digital I/O. 16-Pin Part Pinout Figure 2.
