2.9.7 Bypass Capacitors for A/D Converter
The M3062PT3-RPD-E has the M3062PT3-PRTM (MCU-dependent board 2) board which has a foot pattern for installing
bypass capacitors for A/D converter near the MCU and premounted 0.1μF capacitors. Mount suitable bypass capacitors as
occasion demands. Figure 2.18 shows where they are installed and Figure 2.25 shows their connection.

IMPORTANT

Note on the A/D Converter Function:

z

Because a flexible cable and other devices are used between the evaluation MCU and the user system, the A/D

converter operates differently from that of the actual MCU. Make the final evaluation of the A/D converter
with the actual MCU.
