5.7 Resonator and Oscillator Constants
The resonators for which the operation is verified and their oscillator constants are shown below.
Cautions 1. The constants for these oscillator circuits are reference values based on specific environments
set up for evaluation by the manufacturers. For actual applications, request evaluation by the
manufacturer of the oscillator circuit mounted on a board. Furthermore, if you are switching from
a different product to this microcontroller, and whenever you change the board, again request
evaluation by the manufacturer of the oscillator circuit mounted on the new board.
2. The oscillation voltage and oscillation frequency only indicate the oscillator characteristic. Use
the RL78 microcontroller so that the internal operation conditions are within the specifications of
the DC and AC characteristics.
