2.10.3 A/D Conversion Bypass Capacitors

There is a foot pattern on the R0E3308B0EPBM0 board for mounting bypass capacitors for the A/D conversion circuit near
the MCU. Mount applicable bypass capacitors as occasion demands. Figure 2.19 shows the mounting location of the A/D
conversion bypass capacitors on the R0E3308B0EPBM0 REV.C and structure of this product

Note on the A/D Converter:
• Because a converter board and other devices are used between the evaluation MCU and the user system, the
A/D converter operates differently from an actual MCU. Make the final evaluation of the A/D converter using
an actual MCU.
