Pinouts
The CY8C20x36/46/66/96 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 I/O and connection to the common analog bus. However, Vss, Vdd, and XRES
are not capable of Digital I/O.
16-Pin QFN (No E-Pad)

Notes
LEGEND A = Analog, I = Input, O = Output, OH = 5 mA High Output Drive, R = Regulated Output.
Pin
No.
1. These are the ISSP pins, which are not High Z at POR (Power On Reset).
2. During power up or reset event, device P1[1] and P1[0] may disturb the I2C bus. Use alternate pins if you encounter any issues.
