Answer: You can select a PSoC 3 or PSoC 5 part number when you create a new project in PSoC Creator. The following screenshot shows you how to get started.

Select either ‘Empty PSoC 3 Design’ or ‘Empty PSoC 5 Design’, depending on the project. The ‘Device’ drop-down menu shows two devices by default. The first one is the device that was selected in the latest PSoC Creator project; it says ‘Last Used PSoC 3 Device’ (or it would say ‘Last Used PSoC 5 Device’). The second device shown, CY8C3866AXI-040, says ‘Default PSoC 3 Device’. If you want to select a device that is not one of these two, select ‘Launch Device Selector’.

You may select ‘Launch Device Selector’ even after the project is created (see screenshot below). In the menu bar of PSoC Creator, choose Project > Device Selector. Alternatively, in the PSoC Creator Workspace Explorer window, you can right-click on the project name and choose Device Selector. The following screenshot shows this option.

After you use one of these methods to open the ‘Select Device’ window (see screenshot below), look at the characteristics of the part to help you choose the appropriate part.

You can add or remove columns by selecting ‘Hide / Show Columns’ button on the top left of the window. In addition, you can filter or sort columns to find a device that best fits a particular project.

Another useful feature is the ‘Start Auto Select’ option at the bottom left corner of the window. Before using this option, make sure that the ‘Design Fits on Device’ column is visible. After you press ‘Start Auto Select’, PSoC Creator will start to generate the project on every visible device in the Select Device window. If PSoC Creator can place and route the Top Design of the project for a device, the ‘?’ sign in the ‘Design Fits on Device’ column turns to ‘√’. If an error occurs, the symbol turns to ‘×’. During this process, the ‘Notices’ and ‘Log’ tabs are updated with details of each build. Thus, the ‘Start Auto Select’ option gives you a one-click estimate of the set of devices in which a particular project can fit. Note that this option does not compile the code, and therefore it does not indicate whether the code can fit into the flash of a given device.

Note: For engineering sample (ES) devices, the device revision, such as ES1, ES2, or ES3, is marked on the package as a suffix to the part number. Production silicon will not have ES marking.
