ECD03 Eight-mode Timing Light String IC IC Chip
First, the function description
1. CMOS process, low power consumption. Wide working voltage, strong anti-interference ability.
2. Power-up is the first stage of the light flash mode, and the light flash mode is the normal DC 8 function mode.
Paragraph 1: Automatic continuous change of various functions (i.e. power on) (Combination)
That is, the function automatically changes from the second paragraph to the seventh paragraph
Stage 2: Wave forward and backward automatic change (two speed changes)
Stage 3: Horse Automatic Change (Four Speed Changes) (Sequential)
Stage 4: Single lamp fades on and off automatically (three speed changes)
Stage 5: Horse Forward and Back, Stars Twinkle Automatic Change (Chasing/Flash)
Stage 6: Four lights fade in and out automatically (three speed changes) (Slow Fade)
Stage 7: Twinkle/Flash
Paragraph 8: LED Steady On
3, OPT0 suspension for timing mode, OUT1, OUT2 has output 6H, no output 18H, 24H cycle; There is a crystal oscillator detection mode, no crystal oscillator or crystal oscillator bad power-up no output;
OPT0 is connected to VDD for irregular mode, without adding crystal oscillators.
4. Press the key S1 short press to switch the light flash mode; Long press for 2 seconds to turn off the output; After closing, press and re-output to turn on the timing from scratch.
Second, electrical performance (VDD = 4.5V, GND = 0, Ta = 25 °C)
