Well, ARM have to try and talk up their brand, and they _have_ brought the addresses of all the Keil customers, and doubtless will spam them, but I doubt it will change designers' decision process a whole lot. The core matters less and less, over time : other factors dominate selection. Peripherals, Flash Size, Speed, Pin Count... ( and that has to concern ARM ) -jg

Why am I not surprised. Ian

Can't recall where I saw that, but it is probably including smart cards with 80c51 cores. > >>PICs would own the low-pin-count, Low IQ, business, and the low ASP of >>PICs shows how many rice-grains they ship. - and also shows how slow >>takeup has been on PIC18 and dsPIC. >> >>However, the 80C51 is now moving into the low-pin-count territory, as is >>the AVR, and Zilog et al, so their base-segment is getting more crowded. >>eg at 20 pins, you now have 16K Flash 80C51 variants. >> >>Microchip's analog business is growing faster than their uC's. >> > > > References for the above? ASP, Flash % of shipments, and relative growths are all in Microchips Annual reports (or derived from those numbers). As are development systems, which is another good reality check - tho these numbers look to mean any downloads as a shipped system. -jg

Their ZNEO looks promising, and they just announced that their IDE and C compiler are now free (I guess this applies to all their target families). For the life of me, I can't understand why chip makers haven't done this sooner. Microchip was one of the first to give away their IDE, but that didn't include a C compiler. Atmel's newly enhanced gcc support in their AVR IDE is a nice touch (their debugger is particularly nice as an alternative to the commandline gdb), but Zilog is the first company I know of to give away a commerial C compiler and IDE with no code size limits. I hope this signals a trend in the industry. Chip-makers need to figure out if their primary business is selling chips, or IDEs. Giving away software tools has always seemed like a no-brainer to me. If I were a chip-maker I'd also give away good libs to support my on-chip peripherals... Eric |
