Feature overview

The PSoC™ series consists of an array of many mixed-signal on-chip controller devices. These devices are designed to replace one of several traditional MCU-based system components, low-cost single-chip programmable components. PSoC devices include configurable modules for analog and digital logic, as well as programmable interconnects. This structure allows users to create customized peripheral configurations to match the requirements of each application. In addition, a fast CPU, flash program memory, SRAM data memory, and configurable IO are included in a convenient pin range.

The PSoC architecture, as shown in the figure on the left, is composed of four main areas: core, system resources, digital systems, and analog systems. Combine all equipment resources into a complete customized global bus resource. Each PSoC device consists of 4 digital blocks. According to the PSoC package, two analog comparators and up to 16 general purpose IOs (GPIOs) are also included. GPIO provides access to global digital and analog interconnects.
