AN62510 - Implementing State Machines with PSoC® 3, PSoC 4, and PSoC 5LP

2017 年 5 月 25 日
This application note explains implementation of state machines using the PSoC® 3/PSoC 4/PSoC 5LP family of devices. Mealy and Moore state machine implementations are shown with associated projects.


State machines are commonly used to implement decision making algorithms. State machines are used in applications where distinguishable states exist. A finite state machine (FSM) is based on the idea that a given system has a finite number of states.

This application note shows you how to implement both Mealy and Moore state machines using the Look Up Table (LUT) component in PSoC Creator™. Example projects are included.

The following table indicates the PSoC devices, PSoC Creator versions, compilers, and development kits that will work with this application note project:

Project Device PSoC Creator
Development Kit
架构 Silicon
V2.2 SP1
or higher
V2.1 SP1
042 Pioneer DVK PSoC3 Prod YES*
PSoC4 Prod YES**
PSoC5LP Prod YES* PSoC3 ES2, ES3, Prod YES*
PSoC5 ES1, Prod YES*

* Refer to Migrating CY8CKIT-001 DVK project to CY8CKIT 030/ 050.
** The project can be easily adapted to this DVK.
