This article will comprehensively introduce the functional characteristics, electrical parameters, configuration methods, and typical applications of CXLE87204, helping engineers quickly achieve product design.
1、 Chip Overview and Product Positioning
CXLE87204 is a highly integrated and easy-to-use lighting product control chip that can be adapted to multiple JTM-IC produced single wire protocol LED driver chips and supports breakpoint resume function. This chip is equipped with various common lighting patterns, including filling, flowing, jumping, breathing, waves and other effects, suitable for point light sources, soft light strips, line lights, architectural contour lighting, plant decoration lighting and other scenes.
Unlike medium to large lighting systems that rely on complex controllers, CXLE87204 has implemented“ Ready to use patch” It greatly simplifies the system structure and is particularly suitable for flexible application scenarios such as retail decoration, home lighting, and small commercial lighting.
2、 Core functional features
• Single line serial port outputCompatible with multiple common single line control protocols, supporting cascading up to 600 RGB pixels.
• One click multifunctional operation：
♦ Short press (<0.5s): Switch patterns, with a total of 98 options to choose from;
♦ Middle press (0.5s– 3s): Adjust speed, adjustable in 11 levels;
♦ Long press (>3s): Move back 3 patterns forward.
• Flexible configuration of models: Through ST0‐ The ST3 pin is connected to VDD or GND and can be adapted to various driver chips including CXLE87205, CXLE87152, CXLE87145, etc.
• Power off memory functionAutomatically save the current pattern and speed settings, and resume operation after the next power on.
• Industrial grade reliabilityWorking temperature range: -40 ℃~+85 ℃, ESD anti-static up to 4000V, suitable for various harsh environments.
3、 Pin definition and electrical parameters
CXLE87204 adopts SOP8 packaging, with simple and clear pin functions:
| pin | name | Functional Description |
|---|---|---|
| one | VDD | Positive pole of power supply (4.5V~5.5V) |
| 2– 3,5,7 | ST0– ST3 | Model selection configuration pins |
| four | K | Key input |
| six | DO | Signal output, connected to the first LED driver chip |
| eight | GND | power ground |
The typical dynamic current value of the chip under 5V power supply conditions is 3mA, and it supports a maximum port withstand voltage of 6.5V, with good electrical compatibility.
4、 System design and model configuration
4.1. Typical Application Circuit
The system power supply can be 5V, 12V, or 24V. When VCC>5V, a current limiting resistor Rz needs to be connected in series before VDD:
• 24V → 1.2kΩ ~1.5kΩ (1206 package)
• 12V → 450Ω ~560Ω
• 5V → No resistance required
VDD and GND must be connected with a connection of 0.1 μ m; The decoupling capacitor of F is used to ensure stable operation of the chip.
4.2. Model configuration table

5、 98 detailed explanations of lighting patterns
CXLE87204 comes with 98 preset patterns, divided into eight categories for cyclic operation. Each category's effect can be switched by pressing a button:
1.) Filling effect(9 types): Supports filling methods with different lengths ranging from 3 to 600 points, suitable for lighting up scenes segment by segment.
2.) Flowing water without tailing(16 types): Multiple color combinations, running 5 out of 20 points in each segment, with smooth visual effects.
3.) 10 o'clock flowing tail(9 types): No base color design, running colors can be fixed or gradient.
4.) 30 o'clock flowing tail(9 types): Both fixed color and gradient color modes are supported.
5.) Seven color flowing water cycle(12 types): Supports looping color segments of different lengths from 1 to 35 points.
6.) Monochrome/Mixed/Jumping(9 types): Includes monochrome and mixed color combinations such as red, green, blue, and white.
7.) Gradual overall breathing(10 types): Soft and gradient colors, suitable for creating an atmosphere.
8.) Gradual breathing of waves(16 types): Dynamic wave effect, rich color combinations.
Each pattern runs for about 26 seconds (some models take 40 seconds), with the default speed being the fastest, and users can adjust it in real-time through buttons.
6、 Design considerations
• Synchronization performanceMulti chip systems have slight timing deviations, which may accumulate after prolonged operation. It is recommended to reset them in strict scenarios in a timely manner.
• Color correspondenceThe colors described in the pattern are based on correctly connecting the corresponding LED colors to the RGB channels. If the wiring does not match, the actual effect will be based on the output.
• Power stabilitySuitable voltage divider resistors must be configured for high voltage input to avoid excessive power consumption of the chip.
7、 Recommended application scenarios
• home decorationSoft light strip, bedside light strip, cabinet lighting
• Commercial DisplayShowcase lighting, billboard decoration, festive atmosphere lighting
• Building outlineBuilding line lights, sign frames, landscape lighting
• plant lightingDecorative plant lighting, adjustable color and dynamic effects
