I need to know the writing on/value or exactly what the part is that is
located at IC301 (Right above that label). It's one of those mini 8 legged
pill bug IC's and I need to replace it possibly if I can find out what the
part is. I think I can make out a 2 and an HE but that is about it off the
one that I have access to.

I don't know about the "2 and HE", but this forum talks about a
SAC1630L at location IC301 in an NEC ND-3540:
http://monitor.espec.ws/section5/topic82357.html

Here is its datasheet:
http://web.archive.org/web/200403051...r/SAC1630L.pdf

It has dual LDO regulators (3.4V and 2.7V) and one reset circuit.

The OP in that thread talks about markings such as "993 2 XXP" on the
ND-3520A part.

Thanks for the info. Unfortunately it is not that part being the one at
IC301 has eight legs (4 on each side). The SAC1630L that you mention
apparently has 7 legs on one side and then two larger grounding legs on the
other.

Just found my magnifier and am able to make out more info (disregard the
last info: there is a 993 and under that a 2 and under that is where it gets
tough being its toasted but it looks like it ends with an HD. I do know it
ends in a D though now.

If it helps anybody, here is a photo of the ND-3520A PCB:

All PCBs appear to be using the same chip at IC301. Now I'm confused
about the forum post I alluded to earlier. shrug

I don't feel confident about this one, but it might be worth a look
