Well, the data sheets for various USB controllers have been on the Cypress
Web page for quite some time already...

A micro with 4Kb EPROM & 128 B RAM for $1 in small quantities? Where can I
line up (unless the performance really sucks). Actually it is $1 for
10000+ .

For quantity 1, marshall lists one (2KB EPROM, 128 RAM, 12/6 Mhz, DIP) for
$3.73

Not too bad...
