We were starting a new project and looking for a less than US$1 micro for a very simple app.
It was almost shocking to see the ATTiny11 flavors at less than US$0.40 in very low quantities at US distributors Arrow & DigiKey. Follow-up inquiries revealed that there was a very recent price drop.
I've always wondered where to get the US$0.50 micro for "normal people" that are not building 100,000 of something. I guess now I know. :)
