CY8CLED02-8SXI 概要
An application-specific LED-controller microcontroller is a specialized embedded-control IC that integrates programmable logic, memory, digital I/O, and LED-control functions on one die. In the product hierarchy, the CY8CLED02-8SXI belongs to microcontrollers, specifically the EZ-Color HB LED-controller family. Its role is to execute dimming and lighting-control firmware, manage LED-channel outputs, and reduce the external circuitry needed for dedicated high-brightness lighting systems.
The verified specifications identify 4KB (4K x 8) of program memory, 256 x 8 RAM, six I/O pins, 24 MHz operation, an internal oscillator, and an 8-SOIC package measuring 0.154 inch, or 3.90 mm, in width. The LED-control feature set includes configurable dimmers for two independent channels, 32-bit resolution for each channel, dynamic reconfiguration, and binning compensation. These capabilities make firmware-defined behavior central to the device's value.
The M8C architecture combines embedded program and data memory with six external I/O in a small surface-mount package. A 24 MHz internal clock eliminates the need for an external oscillator when the system design permits operation from the specified internal time base. The 4KB program-memory limit is the principal firmware constraint, so control code should be compact and lighting effects should be selected for repeatability rather than elaborate computation.
Typical uses include high-brightness LED modules, decorative color lighting, fixed architectural accents, display backlighting, compact lamp controllers, and two-channel illumination products where independent dimming is useful. The controller is particularly appropriate when both channels must share an embedded control program but require separate dimming commands. Final electrical suitability still depends on the LED topology, drive current, supply limits, and dimming behavior defined in the manufacturer datasheet.
Designers should preserve the SOIC-8 land pattern and route decoupling close to the supply pins. Because the verified excerpts do not provide complete pin names, voltage limits, timing values, or output-drive details, those items must be checked in the manufacturer datasheet before schematic sign-off. LED current should not be inferred from the MCU I/O ratings without the missing electrical data.
This page consolidates verified distributor specifications, package information, feature descriptions, sourcing links, and engineering-oriented usage guidance. It also distinguishes confirmed data from parameters that still require verification, providing a useful starting point for LED-controller design while avoiding unsupported electrical assumptions.

主な用途
CY8CLED02-8SXI の用途: 6 件s: Dual-Color Decorative Lighting, Architectural Accent Lighting, LED Display Backlighting Control, Two-Channel Status Indicator, High-Brightness LED Module Control, Lighting Effect Controller.
Dual-Color Decorative Lighting
The CY8CLED02-8SXI fits dual-color decorative products because it controls two independent LED channels and provides configurable dimmers with 32-bit resolution per channel. Firmware can maintain relative channel intensity, create smooth transitions, and reconfigure behavior without changing the physical controller. In a typical architecture, the IC runs dedicated lighting effects and issues control signals to the appropriate external LED-drive stage. The supplied data does not identify output-drive current or PWM timing, so engineers must verify those limits and size the downstream driver rather than loading MCU outputs directly.
おすすめ
Architectural Accent Lighting
The CY8CLED02-8SXI is suitable for compact architectural accents where two independently controlled LED groups create color, intensity, or scene effects. Its 24 MHz internal-clock microcontroller executes lighting sequences from 4KB of program memory, while two 32-bit dimmers support fine-grained control. The controller would normally sit beside an external constant-current or constant-voltage LED stage and manage commands through its limited I/O. Mains isolation, creepage, enclosure temperature, and applicable lighting safety requirements remain system-level design obligations and are not established by the supplied component excerpts.
おすすめ
LED Display Backlighting Control
The CY8CLED02-8SXI can manage two backlight channels in a compact display-lighting module because independent dimmers allow different banks or color groups to be balanced. The 32-bit per-channel resolution supports fine intensity steps, while dynamic reconfiguration lets firmware change behavior after startup. A practical implementation would use the microcontroller to supervise external LED drivers rather than power display LEDs directly. Verified PWM frequency, output topology, current rating, and supply limits are absent from the supplied data, so timing compatibility and electrical drive capability must be established from the manufacturer datasheet.
おすすめ
Two-Channel Status Indicator
For a two-channel status or indication lamp, the CY8CLED02-8SXI provides dedicated embedded control without a larger general-purpose MCU requirement. Two independent channels can represent separate system states, levels, or operating modes, and the configurable 32-bit dimmers allow controlled brightness changes between those states. The 4KB program memory is adequate for compact indicator logic when effects are kept deterministic. Designers should keep firmware within the verified memory limits and confirm whether the six I/O pins are sufficient for sensing inputs, communication, and controlling an external driver in the intended product.
おすすめ
High-Brightness LED Module Control
The EZ-Color HB positioning makes CY8CLED02-8SXI relevant to high-brightness LED modules that need two independently dimmed outputs. Its 24 MHz internal oscillator and 6 I/O support embedded sequencing, while 32-bit channel resolution provides fine control granularity. The controller is best positioned upstream of suitable external LED drivers, with decoupling and signal routing implemented on a small 8-SOIC PCB. Because the verified data does not provide continuous-current, pulsed-current, voltage, or thermal ratings, the external driver must be selected from authoritative specifications before the module is energized.
おすすめ
Lighting Effect Controller
The CY8CLED02-8SXI fits repeatable lighting effects that can be divided between two channels, such as dual-bank fading or alternating color sequences. Dynamic reconfiguration enables firmware to change controller behavior, while two configurable 32-bit dimmers provide the execution basis for smooth transitions. The 4KB program-memory limit encourages an effect table or compact state-machine implementation rather than complex graphics. A production design should verify PWM timing and dimming linearity from the manufacturer datasheet, since those quantitative characteristics are not present in the supplied search excerpts.

設計ノート
Use the manufacturer-confirmed 8-SOIC land pattern and pin numbering; the supplied sources verify the package but not its terminal map. Place required decoupling directly beside the relevant supply and ground pins, and keep the LED-control traces away from switching-node edges and high-current LED paths. Treat the controller as a low-power command processor unless the datasheet explicitly permits direct LED drive. No external bypass values are assigned here because the capacitor recommendation and ESR requirements are not present in the verified data.
Do not treat the 32-bit dimming figure as permission to drive arbitrary LED current through a GPIO. The verified excerpts do not include supply voltage, output-drive current, PWM frequency, absolute maximum ratings, or thermal limits. Select the external LED driver from those authoritative limits, verify startup and dimming behavior, and ensure the four program-memory kilobytes are sufficient for the chosen control effects. This prevents firmware overflow, excess current, and inaccurate dimmer calibration.
Plan the PCB around the six-I/O constraint and the 8-SOIC footprint before committing to a two-channel lighting architecture. If sensing or host communication requires more signals, plan an external I/O expander rather than assuming unused pins exist. Keep oscillator and control traces short, maintain a stable return path, and separate LED power routing from the microcontroller area. The internal oscillator removes an external-clock component requirement, but its timing accuracy and allowable configuration must still be checked in the manufacturer documentation.
コンプライアンス情報
The supplied verified excerpts do not explicitly state compliance declarations for the exact ordering code; obtain current documentation from Infineon Technologies before making a compliance claim.
