Schematic

Figure 1-1.

Typical Circuit

Note:

In some systems it may be desirable to connect RST to the master reset signal.

For component values in Figure 1-1 check the following sections:

•

Section 3.1 on page 11: Cs capacitors (Cs0 – Cs5)

•

Section 3.2 on page 11: Series resistors (Rs0 – Rs5)

•

Section 3.5 on page 12: Voltage levels

•

Section 4.4 on page 15: SDA, SCL pull-up resistors (not shown)

•

Section 3.3 on page 11: LED traces
