Select Project > Device Selector in PSoC Creator and choose the appropriate PSoC 3 or PSoC 5 device, as shown in the following figure. Both “ES3” and “Production” revisions of the PSoC 3 device are represented by the same part number in the Device Selector window. For example, in the following figure, CY8C3866AXI-040 represents both ES3 and production revisions of the PSoC 3 device CY8C3866AXI-040.
PSoC 5 devices, which are “ES1” revisions, are indicated with the suffix “ES1” in the Device Selector to match the packaging.
Note: For engineering samples (ES), device revision (such as ES1, ES2, and so on) is marked on the package as a suffix to the part number. Production silicon does not have ES marking.
