CY8CLED04G01-56LTXI

Application Specific Microcontrollers Overview

The CY8CLED04G01-56LTXI is a PowerPSoC intelligent LED driver manufactured by Infineon Technologies, formerly Cypress Semiconductor. It integrates an M8C CPU core with dedicated analog and digital peripherals for high-brightness LED control. The device features four independent LED output channels, each capable of driving strings with typical forward voltages up to 20V at currents such as 350mA. Key internal resources include 16KB of Flash memory, 1KB of SRAM, and various communication interfaces including I2C, SPI, UART, USB, Dali, DMX512, and API support. The component is housed in a 56-pin VFQFN package with an exposed pad.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure correct packaging and temperature grade. Confirm that the component is sourced from authorized distributors to guarantee authenticity, as Infineon continues to support existing part numbers within its portfolio following the acquisition of Cypress Semiconductor.

Application Specific Microcontrollers Selection Notes

Select this component when a single-chip solution is required for multi-channel LED dimming and control. Ensure the design accommodates the 56-pin VFQFN package thermal requirements via the exposed pad. Verify that the available GPIO and peripheral configurations meet the specific interface needs, such as the requirement for USB or specific lighting bus protocols like DMX512.

Application Specific Microcontrollers Part Context

This part belongs to the PowerPSoC family of intelligent LED drivers. It shares architectural similarities with other variants in the CY8CLED0x series, such as the CY8CLED04D01, but differs in specific integrated features and pinout configurations. The 'G' variant typically denotes specific internal resource allocations compared to 'D' variants within the same package footprint.

Application Specific Microcontrollers Replacement Considerations

Direct replacements must match the 56-pin VFQFN package and M8C architecture. Check the CY8CLED04D01 for functional equivalence in similar power applications, noting potential differences in specific peripheral availability or pin assignments. Consult the latest Infineon documentation for any updated cross-reference information.
