Why have ARM based uP/uC not replaced other uP/uC completely yet?

[matrixofdynamism]

Sorry for two questions at once but I just can't find answer to this. The ARM based devices have proved to be very energy efficient and powerful in small devices. What is the reason that ARM has not completely replaced all other microcontrollers and microprocessors on the market?

Hi,

That's almost like asking: "Why are there still cars on the roads that aren't Toyotas ?"

Many reasons...
ARM processors still don't compare with the latest x86 chips when it comes to performance.
There're endless lines of software that has been designed and compiled for x86 (or other) machines and won't work with ARM chips.
Also, ARM isn't the best solution for every problem. A cortex A9 does make for a good low power General Purpose Processor but it isn't the best choice for DSP applications for example.

All microcontrollers including PIC, 8051, 68HC908, AVR, MSP430 etc? Is there an ARM chip in DIP-8 package, that I can use to flash a couple of LEDs ?

Actually, yes there is.

The NXP LPC800 series, an ARM Cortex-M0+ running at 30MHz, is available in a DIP-8 package.

The LPC800 is available in a range of low-pin-count packages, including SO20, TSSOP20, TSSOP16, and DIP8.

NXP LPC800 Series

Final selection of a microcontroller from a group which can equally fulfill the task requirements, often comes down to Price, Preference, Experience and Availability of the device, along with the Programmer's Experience with, Availability and Cost of, the required programming tools for a specific device.

Thanks for the info. I am looking at the ARM development board OM13053 & OM13053,598 from Element 14 and I think they're quite affordable.

I think I'll order this one https://my.element14.com/nxp/om13053/eval-lpcxpresso-lpc812-cortex-m0/dp/2254492 just for a starter.

The DIP-8 chip "NXP - LPC810M021FN8FP" is not that expensive too and I'm going to order 2 pcs for a test drive and see if I like them better than the PIC or not.

Cheers!
