Notes:
1. In principle, the playing speed determined by R
OSC
should correspond to the sampling rate during the coding phase.
The playing speed may be adjusted by varying R
OSC
, however.
2. Rs is an optional current-dividing resistor. If Rs is added, the resistance should be between 470 and 750
.
3. Cs is optional.
4. The DC current gain
β
of transistor 8050 ranges from 120 to 200.
5. All unused trigger pins can be left open because of their internal pull-high resistance.
6. R is used to limit the current on the LED. Case 1: V
DD
= 3V, R = 39
for 1/2/3 LEDs.
Case 2: V
DD
= 4.5V, R = 39
for 2/3 LEDs and R = 100
for 1 LED.
7. No warranty for production.
SUPPLEMENT
A. Power Bouncing
If an irregularity (such as bouncing) occurs in the power supply to V
DD
, as shown in the diagram, the
W528X may hang or the logic state machine may lock up. To return the chip to normal operation,
short V
DD
and V
SS
for the W528X and then release again.
