3. TECHNICAL BRIEF

The PSoC¢‚ family consists of many Mixed-Signal Array with On-Chip Controller devices. 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 blocks of analog and

digital logic, as well as programmable interconnect. This architecture allows the user to create

customized peripheral configurations, to match the requirements of each individual application.

Additionally, a fast CPU, Flash program memory, SRAM data memory, and configurable IO are

included in a range of convenient pin outs.

The PSoC architecture, as illustrated on the left, is comprised of four main areas: the Core, the System

Resources, the Digital System, and the Analog System. Configurable global bus resources allow all

the device resources to be combined into a complete custom system. Each CY8C21x34 PSoC device

includes four digital blocks and four analog blocks. Depending on the PSoC package, up to 28 general

purpose IO (GPIO) are also included. The GPIO provide access to the global digital and analog

interconnects.
