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 PSoC Creator™ to configure the device for the hardware environment.
Introduction
PSoC® 3 and PSoC 5LP devices provide tremendous 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).
When designing a PCB for PSoC 3 or PSoC 5LP, considerations to keep in mind 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 3 or PSoC 5LP 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, to help you to successfully design PSoC 3 or PSoC 5LP devices into a PCB and hardware environment.
