#176869 - Im just trying to provide an argument Responding to: ???'s previous message |
I use the 32-bitters quite frankly. I'm trying to provide counter arguments as everyone on here seems to love the 32-bitters more than the 8052 and the original goal was to help the little guy along in finding it a task to do. I just don't like how people say things like ARM doesn't have the problems that an 8051/2 does in its limited capacity. When people say things like that people tend to think that they don't have to pay attention to detail in their coding. Larger packages are bad in mechanical situations (everyone knows that), but are good under high radiation (as in Jez's case), high humidity (due to pins corroding and shorting in smaller packages), and heat. Of course, that is not specific to the 8052 and is really a generalization of the packaging IC industry making advances without still providing "old fashioned" packaging. Quite frankly, 32-bitters can do the same job an 8-bitter can do, maybe a little more poorly in some applications. If thats not true, then the 8-bitter will never vanish from the market. Just keep in mind ARM is not the only 32-bitter out there, but seems to be a favorite. Don't give ARM too much power or they'll end up like Microsoft. Striaght from ARM:
ARM said:
Three major trends are shaping the MCU space
1: Algorithms increasing in complexity. For example, the desire to make motors more power efficient pushes up the CPU performance requirements. 2: Consolidation of multiple subsystems into a single electronics board, to reduce system cost, footprint and power 3:Platforms that were historically closed are starting to include wired and/or wireless connectivity. This puts further pressures on processor performance requirements and provides additional challenges to the system designer to ensure high degrees of system security/reliability and embed enough latent performance to support future services that maybe delivered across the network to deployed platforms The combination of these three factors will cause the 32-bit MCU market to grow at a rate that far outpaces the growth of other subsegments of the MCU market and indeed the market overall. Don't be surprised if the little guy is hard to find in a few years. |
