These devices are designed to replace multiple traditional MCU based system components with one low cost single chip programmable component. A PSoC device includes configurable analog blocks, digital blocks, and interconnections. This architecture enables the user to create customized peripheral configurations to match the requirements of each individual application. In addition, a fast CPU, Flash program memory, SRAM data memory, and configurable IO are included in a range of convenient pinouts and packages. The CY8C28xxx group of PSoC devices described in this data sheet have multiple resource configuration options available. Therefore, not every resource mentioned in this data sheet is available for each CY8C28xxx subgroup. The CY8C28x45 subgroup has a full feature set of all resources described. There are six more segmented subgroups that allow designers to use a device with only the resources and functionality necessary for a specific application. See Table 2 on page 6 to determine the resources available for each CY8C28xxx subgroup. The same information is also presented in more detail in the Ordering Information section. The architecture for this specific PSoC device family, as shown in the System Block Diagram on page 1, consists of four main areas: PSoC Core, Digital System, Analog System, and System Resources. The configurable global bus system allows all the device resources to be combined into a complete custom system. PSoC C.
