"Oh, so this feature is just totally broken, then? Cool." Always read the errata, folks.

  "Also, we're not fixing the bugs, because customers have already built products that work around the bugs. Fixing the bugs would break their products." Case in point: Microchip ENC28J60 (http://www.microchip.com/wwwproducts/en/en022889 http://www.microchip.com/wwwproducts/en/en022889). Less than half of the advertised features actually work.

    Or the cost of the tape-out outweighs the number of customers using the feature.
    • ianhowson 10y ago
      Yup. The times when I've worked on small-quantity ASICs, tapeout cost and engineer availability have been the main reason that bugs weren't fixed. The ENC28J60 did at least four more silicon revs after the errata were released, so... yay Microchip?

    Yeah, don't use their CAN interface IC's either. Exact same complaint. In general, I now avoid Microchip like the plague. Which means I now avoid Atmel, Micrel, SMSC, etc. <cries>
    • pryelluw 10y ago
      What chips do you use then?
      • bsder 10y ago
        Generally I will go for a built-in CAN controller on a microcontroller. Those generally work fine. Brands? A lot of TI and ST.
