Hello,
I once again return here with some questions and problems.
I'm fixing a Dewalt battery charger and it seems to have a dead microcontroller. Model: Dewalt DCB105
Why i think its dead is well, its not powering on and the VSS and VDD pins are short even after removing it from the pcb. The short on the PCB went away after the removal.
I tried to access it with a programmer but no luck.
The model is PIC16F1936 which seems to be quite a common one.
Now, I have another charger, The same model and all, The pcb-s are identical, But the only problem is that the controller is a different one.
It has the same 28 pins, the outputs/Inputs seem to be the same, But the controller model is: First line N116922, Second line:BD2011Z0D or ZOD neither gave me a datasheet, The third line is Microchip Tech logo and 14142DQ
I find places that have it for sale, Mostly alibaba and other sites like that but no datasheet.
Now what are the chances that its the same PIC16F1936 chip, just rebranded or something like that, and if I would remove it from the working charger, could i use the same programmer to read the chip and write it to a new PIC16F to make a new chip for the faulty charger ?
