#185626 - Why is the MCS-51 family your uC family of preference? |
On a lot of other sites I mention the MCS-51 family of uC's and time after time I get the same response -
"Why would you want to use that family? It's so old/outdated." My philosophy is that the MCS-51 family is still VERY widely used even in today's designs. Most MIDI gear I've worked on uses a uC belonging to the MCS-51 family no matter how old or new it is. I believe some automotive engine/powertrain control computers even still use uC's from this family as well. So there has to be a reason why this family is still favored by many regardless of its age. Me personally, I think the pin out is a very convenient pin out and the instruction set makes coding them in assembly a breeze compared to that of a PIC microcontroller. Plus that...I dabble mainly in MIDI and most MIDI gear uses them, so knowing how to code them also allows me to modify some of this gear. So...I'd like to hear the thoughts/opinions of all of you here. When there are "more modern/updated" uC's on the market with on chip oscillators, more on chip peripherals, higher I/O source/sink capability, etc etc...why is the MCS-51 family still your preferred uC family of choice? |
