That's what I'm trying to determine... it's in a Genie Garage Door Safety Sensor. I suspect some kind of timer. ...Jim Thompson

Likely a custom designed part made specifically for Genie, sold to no one else, and marked per Genie's drawing. Art

According to aftermarket hyenas, Motorola seems to have made something with this number (31199A)in 18dip, and Freescale likewise in 22pin QFN.

This, however could simply be a robotic reaction to recent net searches for the terms motorola, freescale, 31199A and package sizes..........

No electronic format info though. A tricky time for new products (96?). Couldn't have been commercial with that number though...could it?

Probably Micrel. They made a lot of garage door opener parts - mostly custom stuff you won't find online.
