Cypress Semiconductor CY8C27543-24AXI, 8bit Microcontroller, CY8C27543, 24MHz, 16 kB Flash, 44-Pin TQFP

These devices are designed to replace multiple traditional microcontroller unit (MCU)-based system components with one, low-cost single-chip programmable device. PSoC devices include configurable blocks of analogue and digital logic, as well as programmable interconnects. This architecture lets you to create customized peripheral configurations that match the requirements of each individual application. Additionally, a fast central processing unit (CPU), flash program memory, SRAM data memory, and configurable I/O are included in a range of convenient pinouts and packages. The PSoC architecture, as illustrated in Logic Block Diagram, consists of four main areas: PSoC core, digital system, analogue system, and system resources. Configurable global busing allows all the device resources to be combined into a complete custom system. The PSoC CY8C27x43 family can have up to five I/O ports that connect to the global digital and analogue interconnects, providing access to eight digital blocks and 12 analogue blocks.
