LC83015E
No.4013–11/13
The LC83015E has three voltage supply pins (VDD1 to
VDD3) and four ground pins (VSS1 to VSS4). The connec-
tions between these pins must conduct sufficiently to en-
sure that there are no voltage differences between each of
the voltage supply pins and each of the ground pins when
the device is powered-up. Connections similar to those
shown in figure 2 should be used.

Figure 3 shows the connection of a crystal oscilator to the
LC83015E Table 1 shows oscillator frequencies and capaci-
tances for a Nippon Denpa Kogyo NR-18 crystal oscillator.
