I got an EE to bring over an OScope, and we may have found out some more info.
First, we have verified that it is sending programming pulses. Unfortunately, these pulses are only 8.5V for 480microseconds. We've viewed the +12 supply on VPP, and verifed it is 12V. From my understanding, VPP needs to be 12, and that the votage is supposed to be passed through from the VPP pin. Is this correct? Is there any setting that can effect this, or does this sound like a dead chip? Thanks! --Jim On 10/1/07, Jim Kusznir <[EMAIL PROTECTED]> wrote: > I think we're getting close.
