Our local Microchip distributor doesn't stock Industrial grade OTP 12C508. When I asked him why he said that "everybody" just uses the commercial grade instead and that they are actually the same chip, no screening or anything. So I went and ordered the parts I needed from Digikey (industrial). But I still wonder... How would they screen the chips anyways in case the higher temperature range would just cause reduction of the IC's lifetime? (Assuming the same wafer is used...) And what's the deal with 12C508A and 12LC508A? Smaller geometry = lower voltage and lower current? So how come the datasheet indicates higher typical Icc for the 508A than the 508?
