SM16714 Pixel Protocol
A single-wire, self-clocking RGBW pixel chip with an integrated 8-bit-per-channel driver IC in a SOP8 package, daisy-chained over one data line.

Strengths
- Single self-clocking data line keeps wiring simple: there is no separate clock conductor to route, so cabling, connector count and EMI exposure stay lower than on two-wire clocked chips.
- RGBW output adds a dedicated white channel alongside red, green and blue at 8 bits per channel, giving cleaner whites and pastels than an RGB-only chip can mix.
- Wide 5 to 15V pixel supply supports higher-voltage strings, reducing voltage drop and the number of power-injection points over longer runs than 5V-only parts.
Limitations
- No redundant data line: a single failed pixel or broken data joint blanks everything downstream, so critical installs need spare-run or reverse-feed planning.
- 8 bits per channel with a 1000Hz PWM refresh is adequate for the rated 34fps but leaves little margin for very slow high-speed cinematography or deep low-end dimming; it is a mid-range part, not a high-speed film chip.
Overview
The SM16714 is a data-only, single-wire addressable pixel driver: each LED carries an integrated IC that latches its own RGBW value from one self-clocking data line and forwards the rest down the chain. It drives red, green, blue and white at 8 bits per channel across a 5 to 15V pixel supply, with a 1000Hz PWM refresh that is comfortably flicker-free for the rated capture up to 34fps. There is no redundant data line, and the package is SOP8. ENTTEC pixel controllers (OCTO 71521, PIXELATOR MINI and MK2 70067/70068, DIN PIXIE 73539, PLINK Injectors) drive many pixel protocols; contact ENTTEC about chips not listed.
