Anyone here with experience in 18J (= Limited Times Programmable) chips? IIRC the previous bunch claimed to be 1k times programmable, the new chips with ethernet only 100 times! For a developer that is almost OTP... And SMD packages only, so after N (100 or 1k) programming cycles you'll have to ditch your PCB. How do you develop with those chips? Small PCB with only the chip, and ditch only that? How do you know you have exceeded the number of programnming cycles? (how does it show: faulty erase, faulty programming, loss of code after succesfull programming?)
