Does anybody knows any ARM controllers that have a pricing range between $1 to $2. I just need to migrate some 8051 and PIC based product to ARM.

The NXP LPC1114 and others in it's series are pretty cheap. Also the NXP LPC800 series. There is even a 28 pin DIL LPC1114FN28 and an 8 pin DIL LPC810.

The LPC800 is cheaper but having low I/O pin count. I needs minimum 35 I/O pins. The LPC1114 is bit cheaper but still not in my pricing range.

Hello, when it comes to cheap CPU my first association is: Holtek. And yes, they have: 32-bit ARM Cortex™-M3 MCU... http://www.holtek.com/english/products/mcu_71.htmFor prices You have to ask a distributor...

Freescale has Cortex-M0+ parts (the KL2x family) which can go for $1. Some of them include USB. Atmel has recently been advertising very low cost Cortex-M0+ parts as well.

STM32F030F4P6 (48MHz Cortex-M0, 16kB flash, 4kB RAM) at $0.62 at Digikey today (volume price with a reel of 1480 chips).

It looks good, but I cannot find any of these chips in any common distributor (digikey, mouser, avnet). Even worst, their site for samples do not show any Cortex-M3 chip available.

I know only a german distributor: http://www.atlantikelektronik.de/de/index.htmlBest Regards edit: They have a english website too: http://www.atlantikelektronik.de/en/index.html

At farnell the cheapest arm chips (cortex m0) come from nxp (1 euro for the LPC1111), followed in price by freescale and stm.

I've done loads of commercial designs with Cortex-m0 / cortex-m3 NXP 1751 / c11 they are nice processors to work with few errata but nothing major

I purchased the STM32F0 Discovery board for development of two projects last week. Real time debug on board, USB & so on. M0 processor is less than two dollars in single quantities. Development software is free, libraries are free. The board was $10 USD. I couldn't believe there was so much computing power in a processor that is this inexpensive. Freescale has their M0 on a board for the same cost with a few more toys on board.

Hi,
Freescale ARM micros are very good priced. Check them out. There is a new software from Freescale for their Kinetis range, Kinetis Design Studio (it's free), based on their Processor Expert software, very promising. It uses GCC ARM compiler suite.

Well here a link on digikey sorted by price. You have so many options. LINK In my experience use the digikey link as a reference to find the part number you need, and try to search for it using findchips.com or something similar, you will find even cheaper prices. Regards

(Old thread, but options keep changing as time goes by!)
The Freescale MKL25Z32VFM4 is under $2 in the 32 pin QFN package and actually has a nice peripheral set-- ADC, DAC, USB OTG, etc. Makes for a really nice little USB host and Freescale has good USB stack support for free.
Their "Freedom" eval/dev board is one of the best deals out there too... $12.95 USD with the 128K flash part and built in USB hosted debugger.

Cortex M0 is the cheapest 32bit replacement for 8bit microcontroler. Depending upon your requirement of number of pins, package, availability, pricing. you may choose ST or NXP.

Freescale has a 5V tolerant series of ARM devices too, the E series of Kinetis processors. I have just received 10 MKE04Z8VTG4, 20 pin SOIC, very useable for little projects. About $1 each.

I recently purchased some STM32F030K6T6 under $1. It has many pins with 5V tolerant. Or if you need a little more pins STM32F030C8T6 is nice.

They are actually 5V parts, not just 5V tolerant. I dropped them off a design because their documentation sucked.

I am interested with those 5V parts, what kind of sucks did you found? -ichan

I could not easily find design information in the base datasheet, or in the accompanying sheets. They are arrogantly assuming everyone is migrating from their old 8 bit parts. Something as simple as the ISP inteface is like pulling teeth.

Take a look at the microcontrollers:
STM32F072RB -- 1.843$ -- 55 I/O Pins STM32F030C6T6 -- 0.628$ -- 87 I/O Pins
These prices are volume prices.
