Datasheet

Pinouts

The following is the pin-list for PSoC 4100 (44-TQFP, 40-QFN, 28-SSOP, and 48-TQFP). Port 2 comprises of the high-speed Analog inputs for the SAR Mux. P1.7 is the

optional external input and bypass for the SAR reference. Ports 3 and 4 contain the Digital Communication channels. All pins support CSD CapSense and analog mux bus

connections.
