#94802 - Biasing generator for the substrate? Responding to: ???'s previous message |
Jan said:
I don't know what accounts for that 10.5mA, but in all '51 clones I have seen similarly high (several mA) zero-frequency current... I remember, that the 8085 had a built-in generator to bias the substrate by a negative voltage of -2V, in order to enhance the speed of this chip. Maybe the todays micros do something similar? Or maybe it has to do with the code flash memory, maybe this module needs a biased substrate or auxiliary power? The more code space the more static supply current? Kai |
