AN54181 - Getting Started with PSoC® 3

Last Updated: 
Mar 10, 2021

AN54181 introduces you to PSoC® 3, an 8051-based programmable system-on-chip. It describes the PSoC 3 architecture and development environment, and shows you how to create a simple design using PSoC Creator, the development tool for PSoC 3. This application note also guides you to more resources for in-depth learning about PSoC 3 as well as PSoC in general.


PSoC 3 is a true programmable embedded system-on-chip, integrating custom analog and digital peripheral functions, memory, and an 8051 CPU on a single chip.

PSoC 3 provides a cost-effective alternative to the combination of MCU and external ICs. The PSoC 3 architecture boosts performance through:

  • 8-bit 8051 core plus DMA controller and digital filter processor, at up to 67 MHz
  • Ultra-low power with industry's widest voltage range
  • Programmable digital and analog peripherals enable custom functions
  • Flexible routing of any analog or digital peripheral function to any pin 

A single PSoC device can integrate as many as 100 digital and analog peripheral functions, reducing design time, board space, power consumption, and system cost while improving system quality.
