Selecting a Configuration

The first step in building your design is to select a configuration. Click Build and the PSoC Device

Configuration Selection window displays, as shown below.

Figure 3-7. PSoC Device Configuration Selection Window

3.8.1

There are three main parts to this window: a list of available device configurations, configuration properties, and a description of the selected configuration. There are also options to select a bill of materials (BOM) vendor and to automatically assign the drivers to pins on the selected chip.

This window allows you to choose your desired PSoC device along with some system options that include defining system voltage and program loop update rate. It only shows the PSoC configurations that meet the input and output requirements of your design. The configurations are listed in order from least to most expensive.

Configuration Properties

Each configuration has default property values, which you can change at any time. If you select different values, the choices are saved with the design, as is the part or device configuration selection.

Depending upon the selected configuration, you can configure one or more of the properties listed below. Each property option is described in more detail under the section called “Configurable Properties” for the selected configuration.

„

„

Supply Voltage – Selects the supply voltage for the device (Vdd).

Flash Interface – Selects the external access for the Flash.

„

„

Reserved ROM Size – Selects the amount of device Flash memory (in bytes) that is reserved from usage by PSoC Designer auto-generated program code. If an interface is selected (I2C or similar), this memory is available through that interface's protocol (reading and writing).

Sample Rate – Selects the maximum update rate for the system (the rate at which the input-control-output loop repeats).
