ST8024 Application Hardware Guidelines

This section contains some optimization guidelines concerning PCB layout as well as

external component placement and connections. The referenced application board in

Figure 14 and Figure 15 on page 17 has two layers, and uses these guidelines to meet

application NDS requirements.

The PCB layout provides completely separate supply and GND copper planes, which allow

each plan to act as a shield for each group of noise-sensitive device pins. The PGND, and

CGND and GND planes share a common point on bottom layer of the PCB (see top,

Figure 15 on page 17).
