#94814 - flash?
Responding to: ???'s previous message
While the flash certainly contributes to consumption while programis running out of it - the proof is that those low-power mcus have even lower consumption with OTP (E)PROM or maskROM. But their static/low speed consumption with FLASH is still in the 10~100uA range...

A negative-bias producing charge pump is a good candidate of being responsible for the "static" part of consumption, although several mA still sounds too high. But if I remember right, the substrate bias was applied to reduce the risk of latchup. But then, if in powerdown the consumption goes to ~10uA, does this mean that in powerdown there is higher risk of latchup?
