CYCOMP File

What are CYCOMP files and how to open them

Are you having problems opening a CYCOMP file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CYCOMP files.

What is a CYCOMP file?

A .CYCOMP file is a Cypress Components Package file.

Cypress Components Package files are used within the Infineon PSoC Creator development environment to export, share, or import custom peripheral "components" ("design blocks" combining firmware, configuration, symbols, API files, etc.). These files bundle all the parts needed to distribute or reuse a component across one or more PSoC projects.

A component archive is created using PSoC Creator's "Export Component" or "Create Archive" features. It packages the component's symbol files, API source (c/h files), configuration metadata, customizer dialog definitions, and associated graphical and documentation resources. Users then bring the component into other projects via the "Import Component → Import from archive" dialog. Importing retrieves all component definitions and preserves properties such as catalog placement and symbol visibility.

The contributing program is PSoC Creator (Infineon's Windows-based IDE), which both writes and can read these archives. Components in the PSoC Creator Component Catalog may include custom symbol files (.cysm), macro files (.cymacro), source code files, and other support files. When importing a component archive, all components contained within become available in the target project's component workspace.

These package files follow a standard ZIP‐archive style format. Their byte signature begins with the ASCII "PK" sequence at offset 0, and include internal manifest‐type strings such as ".MANIFESTPK" and ".CYSYMPK" that identify component symbol metadata inside the archive.
