CY8CLED16-48PVXI

Application Specific Microcontrollers Overview

The CY8CLED16-48PVXI is an EZ-Color HB LED Controller from the Cypress Semiconductor CY8CLED16 family, designed for intelligent dimming control in high-brightness LED applications. It integrates a 32 KB Flash program memory and 2 KB SRAM data storage on an 8-bit M8C Harvard-architecture processor core. The device supports up to 16 independent LED channels with configurable resolution from 8 to 32 bits per channel. Key features include PrISM modulation technology to reduce radiated EMI and low-frequency blinking, along with extensive analog and digital PSoC blocks for flexible system integration.

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and check for moisture sensitivity indicators prior to soldering. Ensure compliance with RoHS directives and verify that the specific ordering suffix matches the required pinout and thermal specifications for the target PCB layout.

Application Specific Microcontrollers Selection Notes

Select this controller when designing systems requiring up to 16 independently controlled LED channels with high-resolution dimming capabilities. Consider the CY8CLED16 series if the application demands dynamic reconfiguration of analog and digital resources via PSoC Designer software. Evaluate the 48-pin QFN package availability against board space constraints and thermal management requirements for the specific enclosure design.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-Color™ CY8CLED family of Programmable System-on-Chip (PSoC) devices specifically engineered for High Brightness LED illumination. Unlike fixed-function microcontrollers, it offers customizable hardware blocks allowing designers to integrate additional functions such as CapSense, battery charging, or motor control alongside primary lighting tasks within a single integrated circuit.

Application Specific Microcontrollers Replacement Considerations

For legacy replacements, consider the CY8CLED08 or CY8CLED04 variants which offer fewer LED channels but share similar architectural foundations. Verify compatibility regarding GPIO count, memory size, and package dimensions before substituting, as peripheral configurations may differ significantly between model numbers.
