CIRCLE WITH A DOT

Removing the RDL gives us a better view of the die. There seems to be 1 aluminium plating layer plus at least 3 metal layers going down. It's hard to say for sure at this time.2/n

Hellooooo, I see it is #nakeddiefriday today, so here goes.This one is the MC33592FTA by Motorola/Freescale, a RF receiver chip built on a 2-met polysilicon gate CMOS process. The die is rather on the small side, consider the size of bonding pads in relation to the overall area.Full-res map: http://infosecdj.net/map/motorola/mc33592fta-l97p/infosecdj_mz_nikpa60x/#electronics #reverseengineering #microscopy

The standard cell library used elsewhere on the die looks rather unusual; both poly and diffusion features make large excursions outside power distribution rails.At the top of the snippet is what looks like an autorouter bug.
