1. PSoC function overview
The PSoC series consists of many on-chip controller devices. These devices are designed to replace a variety of traditional devices MCU-based system components and a low-cost single chip Programmable equipment. PSoC devices include configurable Analog and digital logic modules, programmable interconnection. This architecture enables users to create Custom peripheral configuration that meets the following conditions The requirements of each application. In addition, fast CPU, flash program memory, SRAM data memory and Configurable I/O is included in a series of convenient pinouts And package.
The PSoC architecture includes four main areas: PSoC core, digital system, analog system and system Resources. The configurable global bus allows a combination of the following functions Integrate all equipment resources into a complete custom system. This The PSoC series can have up to five I/O ports connected to Global digital and analog interconnection, accessible to eight Digital module and six analog modules.
