don't know if there is a version of PIC16C745 that can erase and reprogramer again.

how do I know if the pic erase with ultraviolet ligth or
what is the reference of this type of pic

I wanna buy it, but I wanna be sure to buy the version of window (ultraviolet)

how do I buy this version???? :shock:

 

Ultraviolet erasable versions end in JW, so you need a 16C745JW, you can't mistake it - they are very expensive, probably five times or so the cost of an OTP version.

WARNING!! - be very sure never to set the code protection ON, if you do it means you can't ever erase it!.
