CY8CLED04-68LTXI

Application Specific Microcontrollers Overview

The CY8CLED04-68LTXI is an EZ-Color HB LED Controller from the Cypress Semiconductor (now Infineon) CY8CLED04 family. It integrates a PSoC architecture with an M8C CPU core, 16 KB Flash program storage, and 1 KB SRAM data storage. The device supports up to four independent LED channels with configurable resolution from 8 to 32 bits per channel. Key features include PrISM modulation technology for EMI reduction, full-speed USB 2.0 connectivity without an external crystal, and extensive analog/digital peripherals including ADCs, DACs, and CapSense capability. It operates on a 5 V supply within a -40°C to +85°C temperature range in a QFN-68 package.

Application Specific Microcontrollers Feature Summary

• Configurable dimmers supporting up to four independent LED channels with 8- to 32-bit resolution per channel.
• PrISM modulation technology reduces radiated EMI and low-frequency blinking.
• Full-speed USB 2.0 interface (12 Mbps) with dedicated 256-byte buffer, requiring no external crystal.
• Integrated M8C CPU core with 16 KB Flash and 1 KB SRAM, plus CapSense application capability.

Application Specific Microcontrollers Applications

• LCD Backlight
• Large Signs
• General Lighting
• Architectural Lighting
• Camera/Cell Phone Flash

Application Specific Microcontrollers Procurement Notes

Verify component status as this part may be discontinued or subject to limited availability. Confirm RoHS compliance details through official documentation. Ensure design compatibility with the QFN-68 package dimensions and thermal requirements. Check for updated manufacturer support from Infineon Technologies following the acquisition of Cypress Semiconductor.

Application Specific Microcontrollers Selection Notes

Select this device for applications requiring intelligent dimming control and customizable lighting solutions. Consider the 16 KB Flash and 1 KB SRAM limits for firmware complexity. Evaluate the need for CapSense functionality, which is supported by this specific model but not all EZ-Color variants. Ensure the 5 V operating voltage aligns with system power rails.

Application Specific Microcontrollers Part Context

The CY8CLED04 belongs to the EZ-Color family of Programmable System-on-Chip (PSoC) devices designed for high-brightness LED control. It distinguishes itself from other family members like the CY8CLED02 or CY8CLED08 by offering four LED channels, 56 digital I/O pins, and CapSense support. The '68LTXI' suffix indicates the QFN-68 package, industrial temperature range, and lead-free tin finish.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the same family include CY8CLED02-68LTXI (fewer channels, no CapSense) or CY8CLED08-68LTXI (more channels, no CapSense). Cross-family migration to newer PSoC 1 or PSoC 4/5LP devices requires significant architectural redesign due to differences in peripheral configuration and toolchains.
