To All: if anyone have any kind of documentation please contact me. GeoffOakham: what kind of documentation? Can you contac't me via email? We can exchange ours documentation. (SplinterAlex? - 25 May 2005)

Most of the above details were found the reference documentation provided by Philips. Due to copyright laws, I can't republish that documentation without their permission. As I understand it, providing information from publications--as I am here--is considered "fair use". (GeoffOakham - 10 Mar 2005)

found details of the processor core in this person's CV and this IRC log.. thanks Daniel!

JordanMelzer found this job posting that mentioned code names Philips' uses for these ICs. - edit by RonaldTeune: this page is dead. Google's got no cache; web.archive.org doesn't have it either. Ah well...

Let's just say that googling for "saa7750 pinning" turns up a http://www.google.com/search?hl=en&lr=&q=saa7750+pinning&btnG=Search very interesting result. - DanHollis

Let's just say that googling for "saa7750 pinning" does nothing now. "saa7750 pinout" shows this page and a Taiwanese page, both without interesting info. - RonaldTeune

Looks like something wrong with google. From the US and Japan it works fine, but from iceland it comes up blank. http://www.google.com/search?hl=en&lr=&q=saa7750+pinning&btnG=Search googling for "saa7750 pinning" turns up this data sheet as the first (and only) link. - DanHollis
