7 ELECTRICAL CHARACTERISTICS
CR oscillation frequency characteristic
Note: Oscillation frequency changes depending on the conditions (components used, board pattern,
etc.). In particular, the OSC3 oscillation frequency changes extensively depending on the
product form (chip, plastic package or ceramic package) and board capacitance. Therefore, use
the following charts for reference only and select the resistance value after evaluating the actual
product. (The resistance value should be set to R
