FM0+, FM3 & FM4 MCU

New Contributor II

Hello,

I would like to use a 4MHz ceramic resonator as an external oscillator for FM3 MCU (CY9AF144NAPMC-G-MNE2).

Are there any documents that explain the matching characteristics of oscillation circuits, design guides, or other design methods?

Regards,

Shimamura

Dear Shimamura-san,

have you checked CY9A140NB Series datasheet?

This is the only explanation for Oscillator circuits.

Regarding the matching test, please communicate to Oscillator Vendor for each board..
