Arduino goes ARM

Open Source 2

mikejuk (1801200) writes "The whole world seems to be going in ARM's direction. The latest version of Windows 8 will run on ARM processors, Raspberry Pi is a $25 ARM based machine and now the open source Arduino platform has a new member — the ARM-based Arduino Due announced at the Maker Faire in New York.
The Due makes use of Amtel's SAM3U ARM-based process, which supports 32bit instructions and runs at 96Mhz. The Due will have 256KB of Flash, 50KB of SRAM, five SPI buses, two I2C interfaces, five serial ports, 16 12-bit analog inputs and more. This is much more powerful than the current Uno or Mega.
However it's not all gain — the 3.3V operating voltage and the different I/O ports are going to create some compatibility problems.
Also annouced at the same time are a new low cost board, the Leonardo and a new WiFi shield.
Perhaps Intel should start to worry about the lower end of the processor world."

Intel doesn't care about that world (1)

Perhaps Intel should start to worry about the lower end of the processor world.

Intel doesn't care about that world anymore. They got rid of their low end embedded processors and microcontrollers years ago. There just isn't enough margin in that market to satisfy them. Low end ARM (like the Cortex M3 for example), and other microcontrollers (like TI's MSP430, Pic, AVR, etc) is the domain of companies like TI, NXP, Microchip, Atmel, etc. This is a market for processors that cost well below $10 each individually.

For example, you can buy a little Arduino-like board for the MSP430 for for $4.30 [] , if you look around you can find ARM Cortex M0 chips for around $1 each (in single unit quantities).

This isn't a market Intel cares about. They want the higher end of the embedded market, but not the microcontroller market.

With Windows about to move away from x86 to ARM processors perhaps Intel should have taken more interest in the lower end. Embedded processors might be cheap but they sell in large numbers and sucess in this area has allowed the ARM design to spread. I take your point that Intel doesn't get the margins it needs from low end processors but perhaps this is exactly why it is being threatened by designs that work in the low power low cost arena.
