This is the link to IntellaSys' spec sheet. IntellaSys is the division of TPL that managed the SEAForth project. The S40 chip was the ultimate product of that effort. I was chief designer and contributed 55% of the $40M, or so, that it cost.

<p>TPL laid off SEAForth employees in January 2009 and thus terminated the project. The status and future of S40 chips is unclear.
