AN61290 - PSoC® 3 and PSoC 5LP Hardware Design Considerations

Last Updated: 
Sep 21, 2017

AN61290 reviews several topics for designing a hardware system around a PSoC® 3 or PSoC 5LP device. Subjects include power system, reset, crystal, and other pin connections, and programming and debugging interfaces. Also included are instructions on how to use the PSoC Creator™ IDE to configure the device for the hardware environment.


PSoC® 3 and PSoC 5LP devices provide power and flexibility for analog and digital applications, beyond what traditional MCUs offer. However, this flexibility raises new considerations when designing a PSoC device into a printed circuit board (PCB).

These considerations include proper connections for device power, reset, crystal, programming, and other pins. Good board layout techniques are also important, especially for precision analog applications.

Finally, the PSoC device must be configured to work optimally in its hardware environment. The PSoC Creator™ IDE is used for this purpose.

This application note provides information on each of these topics, so that you can successfully design PSoC into a PCB and hardware environment.
