Description
The P34-RGB05P02N3P1IMA03-CC is an addressable RGB LED from Shenzhen H-Great Optoelectronic in a 3.4 x 3.3 x 1.9 mm PLCC-6 SMD package. It integrates a constant-current driver IC with 8-bit PWM control (256 grayscale levels per channel) and a single-wire serial data interface running at 800 Kbps. The device supports daisy-chain cascading via DIN/DOUT for LED strip and matrix applications.
Features
- Integrated constant-current driver with 8-bit PWM per R/G/B channel (256 grayscales)
- Single-wire NRZ serial data interface at 800 Kbps
- Viewing angle: 120 degrees
- Supply voltage: 3.5 - 5.5 V (VDD)
- Maximum output current: 12 mA per channel
- ESD protection up to 2 kV
- MSL: Level 3
- RoHS compliant
- Daisy-chain cascading via DIN/DOUT

24-bit Data Structure (GRB order)
Data is transmitted MSB first in Green-Red-Blue order: G7-G0, R7-R0, B7-B0 (24 bits per LED).
Connection Notes
- Add 100-200 ohm series resistor between DOUT and next DIN for signal isolation
- 0.1 uF bypass capacitor on VDD pin required for stable operation
