PSoC® Creator™ Integrated Design Environment (IDE)

PSoC 6 Chip Image

To evaluate and design with all available PSoC 6 MCUs, please download the ModusToolbox SW environment

Note* If you are currently using PSoC 6 and PSoC Creator, please continue to use PSoC Creator for development. If you have interest in starting a design with the PSoC 62 with up to 2MB Flash, 1MB SRAM and 104 GPIOs, please use the ModusToolbox SW environment.


PSoC Creator is an Integrated Design Environment (IDE) that enables concurrent hardware and firmware editing, compiling and debugging of PSoC and FM0+ systems. Applications are created using schematic capture and over 150 pre-verified, production-ready peripheral Components.

PWM Component CustomizerComponents are analog and digital peripherals represented by a symbol that users drag-and-drop into their designs and configure to suit a broad array of application requirements. Each Component in the rich mixed-signal Cypress Component Catalog is configured with a customizer dialog and includes a full set of dynamically generated API libraries. After configuring all the peripherals, firmware can be written, compiled, and debugged within PSoC Creator or exported to leading 3rd party IDEs such as IAR Embedded Workbench®, Arm® Microcontroller Development Kit, and Eclipse™.

PSoC and FM0+ Systems are energy optimized beyond a typical MCU because PSoC Creator optimizes designs to enable only the required functionality. Users can even create custom Components using state machine diagrams or Verilog to further optimize hardware and energy usage.

PSoC Creator is a free Windows-based IDE that includes:

  • Hardware design with complete schematic capture and easy-to-use wiring tool
  • Over 150 pre-verified, production-ready Components
    • Full communications library including I2C, USB, UART, SPI, CAN, LIN, and Bluetooth Low Energy
    • Digital peripherals with powerful graphical configuration tools
    • Extensive analog signal chain support with amplifiers, filters, ADC and DAC
    • Dynamically generated API libraries
  • Free C source code compiler with no code size limitations
  • Integrated source editor with inline diagnostics, auto-complete and code snippets
  • Built-in debugger

What's New in PSoC® Creator 4.4?

PSoC Creator 4.4 is a minor upgrade from PSoC Creator 4.3 and adds the following features.

  • Support for the CY-PD® PAG1S product family
  • Support for new USB Type-C CCG7D and CCG3PA devices
  • Fixes for defects in the PSoC 6 ECO setup code generated from the System Clock Editor
  • Fixes for analog routing errors with PSoC 4100S Plus devices

What's New in PSoC® Creator 4.3?

PSoC Creator 4.3 adds support for the exciting new PSoC 4500 product line for Home Appliance, Motor Control, Consumer and Industrial applications. These devices have a unique analog architecture, featuring two complete Programmable Analog Sub-System (PASS) blocks, which enable more sophisticated analog designs than ever before.

They also boast a generous 256kB flash and 32kB SRAM on-chip memory, so you won’t run out of program space, no matter how ingenious and complex your design.

Create Project - CY8C4548AZI-S485

In addition to the PSoC 4500, this release also adds support for a host of new devices in existing product lines.

  • PSoC 42100S devices with up to 256kB flash memory and 32kB SRAM
  • New PSoC 6 devices in the 68QFN package

PSoC Creator is packed with amazing technology to simplify the development of embedded applications with Cypress MCUs and PSoC devices. From your very first day with the tool, our schematic design capture interface and rigorously-tested peripheral components enable you to create a reliable, customized SoC that is perfect for your application.

Error-Free Project Creation

Simply select the target kit, module or part number, then choose your project name and location and your new project gets set up perfectly every time.

  • Device startup files
  • Register definitions
  • Linker scripts
  • Driver libraries

Add Functionality with Project Templates

Starting a project from scratch can be hard so PSoC Creator provides a variety of useful start points that enable functionality before you write a line of code.

The Power of Components

PSoC is the most customizable microcontroller in the World. With device configuration and schematic capture, PSoC is also the easiest microcontroller for engineers to use.

  1. ​Place and connect your Components on the schematic
  2. Customize your Components using a simple wizard

  3. Build your custom device

Image 2

Components include the ability to generate firmware. This means you always have the right version of the API and can skip the error-prone task of populating configuration structs to set up peripherals.

Create Your Perfect SoC

Schematic capture lets you “design the way you think”. You just draw the device that is perfect for your application. The wiring tool makes it simple to connect peripherals together the way you need them, not the way the chip designer thinks it should be.

PSoC devices are famous for supporting almost “any function to any pin” and the built-in Pin Editor lets you change physical pin choices safely and rapidly. The drag-and-drop interface simply won’t let you choose an illegal pin and uses pin coloring to direct you to the most resource-efficient choices (green pins have direct connections to your peripheral and yellow pins require routing through the programmable fabric).

Never Run Out of Resources

When you build a project in PSoC Creator it updates a Resource Meter display that shows you the hardware used in the design. You can see how much head-room you have and get an early warning of over-used resources.

Image 5

PSoC devices are available in many families and series, providing a broad range of resource combinations to choose from. In the unlikely event that you run out of resources, there is usually another device you can choose that will fit the bill. With PSoC Creator this is not a problem at all, simply launch the Device Selector, pick your new part, and rebuild to effortlessly re-target the design.

Error Proof Your Design

No development tool is as closely tied to the silicon as PSoC Creator. It is packed with error-prevention and labor-saving functions that steer you away from device configuration and firmware library problems from the beginning of a project to its completion. This makes it easy for you to create a customized SoC at a fraction of the cost and risk of ASIC development and without the trade-offs (and expensive firmware workarounds) you get with a fixed-function microcontroller.

Simple Multi-Core Development

The PSoC 6 family includes several devices that are multi-core with a 150 MHz main Arm® Cortex®-M4 core coupled with a Cortex-M0+. PSoC Creator makes it easy to develop powerful, efficient applications on these devices with a number of unique features.

  • Easily navigated Workspace Explorer view with separate trees of source code
  • Driver and middleware source code is always available on both cores
  • Interrupt editor helps you pick the core you want to run the ISR
  • Sophisticated new build system always generates a combined image for download
  • Rapid selection of the target core for debugging
