#125557 - Static power consumption Responding to: ???'s previous message |

Bipolar technology appears to be so much quicker and faster than NMOS/CMOS, but cpu manufactures still insist on using NMOS/CMOS, I wonder what the problem is? Static power consumption is the issue here: Compare the idle currents of a 74HC00 and 74LS00 gate, and you will see what I mean. Darren said:
That said, my ALE line on my AT89C51ED2 seems to be ringing quite badly, when running 1mip or 5 mips. Ringing on ALE can be seen when having too much capacitive load on the ports, and when wronlgy using the osci-probe: Take the spring contact shown here (red arrow pointing on it) as ground connection to avoid probe ringing:  Kai |
