I remember reading about the Anadigm FPAAs, but I don't recall finding anyone who sold them.
The Cypress pSOC series is fairly similar (programmable analog blocks mated to a Cortex-M microcontroller core) and easier to find on sale. I'd argue that it's also more useful in modern mixed-signal designs.
