FM0+ S6E1C series : ARM core operating lower limit frequency

Hi,

We are considering low power applications.

We have confirmed for "32 Bit Microcontoroller FM0+ Family Peripheral Manual"
The frequency division (1 to 16) exists in the P.44 Figure 2-1 block diagram below.

Assuming this block diagram, will the ARM Cortex-M0+ operate at 500kHz, which is a division of 8MHz into 16?

If it works at 500kHz, Do you know the current consumption at the set clock?

Regards,

Regarding current consumption at 500KHz, there is no data unfortunately.

To get rough estimation, please refer to the datasheet.

The range current consumption at 500KHz would >100KHz and <8MHz.

And as other solution, it would be suggested that you measure the current consumption at 500KHz.

Thank you.
