In a latest video, [Andrew Zonenberg] takes us via the method of decapsulating a PIC12F683 to take a peak at its CMOS implementation.
It is a multipart sequence with 5 elements completed and extra to come back. The PIC12F683 is an 8-pin flash-based, 8-bit microcontroller from Microchip. [Andrew] picked the PIC12F683 for decapsulation as a result of again in 2011 it was the primary microcontroller he broke read-protection on and he needed to return and revisit this chip, given notably that his assets and abilities had superior within the intervening interval.
The 5 movies are a tour de drive. He begins by taking a bundle cross part, then decapsulating and delayering. He collects high-resolution images as he goes alongside. Within the course of, he takes a while to clarify the risks of working with acid and the danger mitigations he has in place. Then he does what he calls a “floorplan evaluation” which takes inventory of the complete chip earlier than taking an in depth have a look at the SRAM implementation.
