5.7 Resonator and Oscillator Constants
For the resonators for which the operation is verified and their oscillator constants, refer to the target product page of the
Renesas Electronics website.
Caution 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.
Caution 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.
