Hello,
I'm searching for an 8-bit microcontroller that would provide 5V PWM at frequencies up to 100 kHz with solid duty cycle control.
(I need it for fast H-bridge switching and basic regulation, so I only need good PWM and ADC)
Do you have any advices?
Hi
Several S08 device can support a PWM of 100 KHz, but if you need motor control please check the MC9S08MP family
8-bit General Purpose MP MCUs|NXP
I hope this will help you.
Please let me know if you have more questions
regards
Vicente Gomez
Thank you for your answer.
I will definitly consider using MC9S08MP, however its hard to get the 48-pin version in czech republic.
Do you think MC9S08DZ family is suitable as well?
Yes the MC9S08AC can be also a good option, as I remember if runs at 20 Mhz of bus clock and the TMP (this device has TPM) runs at bus clock/4 = 5 MHz so there is no problem to run at 10 KHz
Please let me know if you need a sample code
Have a good day.
Regards
Vicente
Hello.
I have reduced the amount of pins used, so I will probably use 32-pin MC9S08MP16 as you suggested.
However I have no experience with FTM. Could you please send me a sample code?
Thank you very much.
