Application Specific Microcontrollers Procurement Notes

Verify component status as the CY8CLED04 series may be discontinued or subject to limited supply conditions. Confirm package availability and lead times through authorized distributors. Ensure design-in compatibility with current firmware tools such as PSoC Designer before procurement.

Application Specific Microcontrollers Selection Notes

Select this model for applications requiring intelligent HB LED control with customizable dimming profiles. Verify that the 68-pin QFN package fits the PCB layout constraints. Ensure the application utilizes the available GPIO count and analog resources, noting the specific pin assignments for I2C and USB interfaces.

Application Specific Microcontrollers Part Context

This component belongs to the Cypress Semiconductor EZ-Color family, now part of Infineon Technologies. It is designed for lighting designers needing a fully customizable platform combining PSoC flexibility with precise illumination signal modulation. The device integrates programmable analog and digital subsystems for in-field tuning.

Application Specific Microcontrollers Replacement Considerations

Check for direct substitutes within the EZ-Color family such as CY8CLED02, CY8CLED08, or CY8CLED16 based on required LED channel counts and memory sizes. Verify pinout compatibility if replacing with other PSoC 1 devices.
