I'm looking for information on the typical max frequency (or typical frequency range) for the Cortex-M cores, in 40nm. Is there any documentation on that? Thanks.
This NXP paper (https://www.nxp.com/docs/en/white-paper/I.MXRT1050WP.pdf) mentioned that they are using 40nm for iMX RT (Cortex-M7). The current devices run at 600MHz. Cortex-M7 is 6 stage pipeline so it is faster than other Cortex-M processors at the same process node.
Several Cortex-M4 microcontroller series run at up to 240MHz. But no public domain information about the process nodes.
This link (https://www.st.com/en/microcontrollers/stm32-high-performance-mcus.html?querycriteria=productId=SC2154) provides some information on clock freq range and process node.
