FM0+, FM3 & FM4 MCU

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?

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.

ARM Cortex-M0+ can be operated at 500KHz.

And regarding the current consumption data @ 500KHz, it is now checking whether there is data, or not.

thank you.

Thank you for your support.

We were relieved to hear that it works at 500kHz.

We need the active current to be less than 300uA.

If you have current consumption data at 500kHz, please let us know.

Thank you for your support.

Referring to the specifications of the data sheet,

Actually measure and confirm.
