1. These capacitors must be < 350 mΩ ESR and be placed near the IC (within 10 mm).
2. ST8024L and the microcontroller must use the same V
DD
supply.
3. Make short, straight connections between CGND, C5, and the ground connection to the capacitor.
4. Mount one ESR-type (< 350 mΩ) 100 nF capacitor close to pin V
CC
.
5. Mount one ESR-type (< 350 mΩ) 100 nF capacitor close to C1 contact.
6. The connection to C3 should be routed as far as possible from C2, C7, C4, and C8 and, if possible, surrounded by
grounded tracks.
7. This is the optional resistor divider for changing the threshold of V
DD
when using the PORADJ function. If this divider is not
required, pin 18 should be connected to ground.
