AN84741 - PSoC® 5 to PSoC 5LP Migration Guide
If, instead of PSoC 5, you want to migrate from a PSoC 3 design to PSoC 5LP, see AN77835, PSoC 3 to PSoC 5LP Migration Guide.
The PSoC 5 and PSoC 5LP devices are designed for easy migration from PSoC 5 to PSoC 5LP. Although there are some differences such as additional features in PSoC 5LP, the programmable analog, programmable digital, programmable routing, pin functions, and other features are quite similar. Furthermore, the PSoC Creator IDE handles a lot of the migration issues for you, automatically. Often, migrating a PSoC Creator design is as simple as specifying a new part and then rebuilding the project.
