8. Pin Information
This section describes, lists, and illustrates the CY8C24x94 PSoC device family pins and pinout configuration.
The CY8C24x94 PSoC devices are available in the following packages, all of which are shown on the following pages. Every port pin
(labeled with a ā€œPā€) is capable of Digital I/O. However, V
SS
, V
DD
, and XRES are not capable of Digital I/O.
8.1 56-Pin Part Pinout
Notes
3. This part cannot be programmed with Reset mode; use Power Cycle mode when programming.
4. These are the ISSP pins, which are not High Z at POR. See the PSoC Technical Reference Manual for details.
