4516 Dual-Wire Addressable RGB SMD LED
4516 Side-emitting RGB Two-wire Addressable LEDs - Hongcheng Optoelectronics LED Manufacturer
Product Overview:
The 4516 two-wire addressable SMD LED uses an elongated package approximately 4.5×1.6×1.6mm, integrating RGB LED chips and a control IC. A data line and clock line work together to control color and brightness. The clear flat encapsulant and compact structure suit narrow layouts. Cascading multiple LEDs with a controller enables fades, flowing, chasing and breathing effects for consumer electronics, addressable LED bars and ambient decoration.

- Elongated 4516 SMD package facilitates compact PCB layouts
- Integrated RGB LED chips and control IC
- Two-wire data and clock transmission with multi-LED cascading
- Individual-pixel color and brightness control for flexible lighting sequences
- Works with a controller for fades, chasing, breathing and other effects
- Clear flat encapsulant readily combines with light guide and diffusion structures
- Compatible with automated placement equipment and reflow soldering
Applications:
- Addressable decorative lighting in consumer electronics
- Lighting effects for keyboards, mice and gaming peripherals
- Audio systems, headphone bases and desktop ambient lighting
- Smart home control panels and interactive indicators
- Small addressable RGB light bars, light rings and lighting modules
- Light guide structures and lighting effect designs for narrow areas

No Data
4516 Dual-Wire Addressable RGB SMD LED (Complete part number: HC-IC4M32-B4516RGB16ZCG) integrates RGB emission channels and a control IC, using dual-wire synchronous serial control with data DIN and clock DCLK. The datasheet specifies sampling DIN on the rising edge of DCLK, with data and clock forwarded to subsequent devices through DOUT and DCLKO respectively. The product uses a clear flat encapsulant and a six-pad SMD structure, suitable for controller-based multi-device cascading and dynamic lighting effects. Follow this model's PDF for power supply, communication and soldering conditions.
Q: Does 'two-wire' mean two data lines or backup data transmission?
A: No. This model's two input signals are the DIN data line and DCLK clock line, using synchronous serial communication. Do not wire it directly as a dual-data backup or single-wire addressable protocol. The controller program must match this model's clock sampling method and 32-bit data frame format.
Q: What are the placement and soldering requirements for this LED?
A: Design the PCB and placement program using the engineering dimensions, six pad functions and mounting orientation for the corresponding part number. Follow its datasheet for reflow, storage and ESD protection. Confirm dimensional and pad drawings before volume PCB production; do not directly reuse another addressable LED's footprint or pinout.

Selection Recommendations
This part uses two-wire synchronous serial control via DIN data and DCLK clock lines. Do not wire it for a single-wire addressable protocol or dual-data backup arrangement. The controller must match the datasheet's clock sampling, 32-bit data frames and input/output direction. VDD is the IC supply parameter, not an individual LED channel's VF; ordinary LED current-limiting resistor calculations cannot replace IC supply design. Before PCB fabrication, confirm engineering dimensions, pads and all six pin functions, and check supply, cascading and soldering conditions against the corresponding datasheet.
