4.3.1 Connection diagram of R0E521000EPB00
Figure 4.1 shows the part of the connection diagram of the R0E521000EPB00. This connection diagram mainly shows the
interface section. The circuits not connected to the user system such as the emulator's control system are omitted. The signals
not shown in Figure 4.1 connect the evaluation MCU and the user system directly. Table 4.2 shows IC electric characteristics
of this product for reference purposes.
