AN72382 - Using PSoC® 3 and PSoC 5LP GPIO Pins

Last Updated: 
Mar 02, 2021

AN72382 shows you how to use GPIO pins effectively in PSoC® 3 and PSoC 5LP. Major topics include GPIO basics, configuration, mixed-signal use, registers, interrupts, and low-power behavior.


The any-signal-to-any-pin routing available with PSoC® 3 and PSoC 5LP GPIOs helps to optimize PCB layout, shorten design time, and allow a large degree of solderless rework. However, with this freedom comes a steeper learning curve than with a traditional microcontroller. This application note introduces you to PSoC 3 and PSoC 5LP GPIO basics and demonstrates techniques for their effective use in a design.

Dear valued customer,

Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you. 

Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
