When the chip is in Sleep mode, running at 1MHz (or slower) using the HSI, the chip uses 440 micro amps.
I'm curious, where is this current being used?
Many of my applications run off lithium coin cells, which can't supply much current without having the voltage drop noticeably.
For example, assuming a peak maximum supply current of 1 milliamp, I could run a TI MSP430F149 at around 4MHz or the STM32 at 1MHz. From my rough calculations and testing I would be able to do more taps of an FIR filter using the MSP430F149 (although once I become more familiar with STM32 assembler code I might be able reverse this situation).
