Essentially, that is the core difference. This then leads to the following question: what are the differences between microcontrollers and microprocessors? For an introductory answer refer to this thread.At a very high level, ARM's are more like microprocessors, and PIC's are more like microcontrollers.
I don't agree with this; most ARM chips have peripherals, just like other micros. I have a Phillips chip (LPC) right here with multiple serial - 2 UARTs, 2 I2C, 2 x 32 bit timers, ADC, and 512k of Program, and 32k static RAM. Phillips refers to them as microcontroller, and I'm sure the other makers of ARM refer to their products as microcontrollers.ARM's are more like microprocessors, and PIC's are more like microcontrollers.
I finished my project last week. I posted this to know other micros and get helpfull information from you.Can you be more specific about your need?
What about AVR32?I think the main difference is that ARM uses a 16/32 bit data bus, where other micros use an 8 bit bus.
I also find them quite a bit harder to use, and way more powerful than PICs or AVRs.
