Matt Sarnoff wrote in to let us know that his ChipDB project just went live:

Instead of digging through hundred-page PDF datasheets to find the pinout of a microcontroller or logic chip, you can use a simple URL scheme (example: to get the data right away.

Its collection is currently small, but includes the most common chips; Atmel microcontrollers, 4000 series, 7400 series, LMxxx series, and more. There’s a bookmarklet for one-click lookups and a keyword search that lets you find a part even if you don’t know its number.

Users can contribute their own entries to the database. Since the site is in its infancy, I currently moderate all submissions, but I hope to change this in the future if demand is great enough.

ChipDB – integrated circuit quick reference

I’m a tinkerer and finally reached the point where I fix more things than I break. When I’m not tinkering, I’m probably editing a book for Maker Media.

    Happy cat :D

    Wha?! – the mark II chips are shipping already?!?

    This is a great idea – cant wait until the database grows a little.

    I have one suggestion. Rather than limiting it to “chips”, you may want to consider expanding it to include all semiconductors that would have a datasheet.

    You could easily include a section for diodes (1N4007) that would include information about breakdown voltage, maximum amperage etc.

    I think this is a great effort.
