Check the datasheet/user manual for the devices, the markings are normally explained in there.
It could just be a batch number or code.

The 1B4 is the chip family and flash size.
I don't recognize the other code, but it's likely a date/batch code.

j3c0 does not connect to the debugger. Why can it be?
