Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm silicon revision status as this family may be superseded by newer series. Ensure compatibility with legacy development tools such as PSoC Designer when sourcing replacement units for existing designs.

Selection Notes

Select this component when design flexibility for analog and digital functions is prioritized over fixed-function microcontrollers. Consider the 24 MHz clock speed and available I/O count against system requirements. Evaluate the need for programmable filters or capacitive sensing modules supported by the analog array before finalizing the part number.

Part Context

This device belongs to the CY8C26xxx PSoC family, which integrates a CPU with programmable analog and digital blocks. It serves as a single-chip solution replacing multiple discrete components. The family emphasizes design time reduction through graphical configuration tools and modular peripheral selection.

Replacement Considerations

Official documentation indicates the CY8C27xxx series as the recommended replacement for new designs due to architectural updates.
