The only parts of the 805x architecture that I've ever found even a teensy bit interesting are the DS89C4x0's. I'm considering bringing in a number of them as stock, as I have only the engineering samples that Maxim, and, previously, Dallas, provided, but I won't do that until I get a thorough incoming inspection regimen set up.
As I said, I've been screwed once too often by the distributors, and I don't do mass-production myself. This means that they consider me "small-potatoes" at best, and will happily send me rejects from the megacorp down the street. I expect my stock parts to be as "perfect" as I can verify. It's not truly perfect, but I don't want to have a situation arise wherein I have a lot of parts on the shelf of which some function properly and some don't. That may not be important for large-volume producers, but I do handfuls at the most. My clients operate differently, of course. I'm still at the stage of determining what, exactly, I can resonably verify, and how I can do it. Maybe a device-specific, test-vector-based test fixture using an FPGA and controlled by a PC would be the "right" way to do it. In my particular case, I have to be sure that all the functions of the MCU are intact. I can't just hope. I can't satisfy myself that it "works" for a specific case, as I don't know what the next case will require. RE |
