I want to use Renesas RH850/F1X series to generate PWM frequency in the range of 25KHz to 50KHz for my application. As per RH850_PWm pdf we can generate max PWM frequency upto 4880Hz with 40MHz. How can I achieve my expected PWM frequency when RH850/F1X series support upto 240MHz clock frequency.
The PWM module is not only one way to generate PWM signals. Its main purpose is to generate PWM for external devices like LEDs, where low frequencies are acceptable. PWM signals can even be generated using standard timers like TAUx. E.g. TAUDn can run up to 80 MHz (depending on the desired RH850 MCURead more
The PWM module is not only one way to generate PWM signals. Its main purpose is to generate PWM for external devices like LEDs, where low frequencies are acceptable. PWM signals can even be generated using standard timers like TAUx. E.g. TAUDn can run up to 80 MHz (depending on the desired RH850 MCU). The period and pulse width can be adjusted individually. Using an 80 MHz clock supply limit the bit width for the PWM to 10 Bit(80MHz/10Bit=78kHz).
