Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'LFXI' against the official Cypress datasheet to confirm package type (48-LQFP) and temperature grade (-40°C to +85°C). Confirm RoHS compliance status as manufacturing processes may vary by production batch. Check for obsolescence notices from Infineon Technologies, the successor to Cypress Semiconductor, before finalizing procurement plans.

Application Specific Microcontrollers Selection Notes

Select this component when a single-chip solution is required for driving multiple high-power LEDs with synchronized color effects. Compare channel count and current drive capabilities against the CY8CLED08 series if fewer outputs are sufficient. Ensure the system design accommodates the thermal requirements of the 48-pin LQFP package under maximum load conditions.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-Color™ HB LED Controller family, which simplifies the design of complex lighting systems by integrating control logic and power drivers. The CY8CLED164 variant offers a higher channel count compared to lower-density models in the same series, targeting professional lighting applications.

Application Specific Microcontrollers Replacement Considerations

Direct pin-to-pin replacements should be verified against Infineon's current product portfolio. Consider the CY8CLED08-48LFXI for applications requiring fewer than eight channels. Cross-reference electrical specifications such as max output current and operating voltage ranges to ensure compatibility with existing LED loads.
