Note
The oscillator circuit parameters provided below are the result of tests carried out by the oscillator manufacturer
under fixed operating conditions. (please refer to the table as below for the measurement data). Peripheral
environment effects on the customer's system such as noise, high frequency, wiring pattern, power source
characteristics, etc., were not taken into account at the time of testing. Values may therefore differ for actual
systems. In addition, RENESAS does not guarantee these parameters. Please use these values only for your
reference. Customers should contact the oscillator manufacturer for the optimal oscillation circuit parameters
applicable to their system.
