what is best arm company ??

hiiiiiiiii :-D
there are alot of arm company like(atmel,nxp,st)
i want compare between arm company in the (cost , educational resource, application note,...etc

The relative simplicity of ARM processors makes them suitable for low power applications. As a result, they have become dominant in the mobile and embedded electronics market, as relatively low-cost, small microprocessors and microcontrollers. In 2005, about 98% of the more than one billion mobile phones sold each year used at least one ARM processor. As of 2009, ARM processors account for approximately 90% of all embedded 32-bit RISC processors and are used extensively in consumer electronics, including personal digital assistants (PDAs), mobile phones, digital media and music players, hand-held game consoles, calculators and computer peripherals such as hard drives and routers.

The ARM architecture is licensable. Companies that are current or former ARM licensees include Alcatel-Lucent, Apple Inc., AppliedMicro, Atmel, Broadcom, Cirrus Logic, Digital Equipment Corporation, Ember, Energy Micro, Freescale, Intel (through DEC), LG, Marvell Technology Group, Microsemi, Microsoft, NEC, Nintendo, Nuvoton, Nvidia, Sony, NXP (formerly Philips), Oki, ON Semiconductor, Psion, Qualcomm, Samsung, Sharp, STMicroelectronics, Symbios Logic, Texas Instruments, VLSI Technology, Yamaha, and ZiiLABS.

ARM processors are developed by ARM and by ARM licensees. Prominent ARM processor families developed by ARM Holdings include the ARM7, ARM9, ARM11 and Cortex. Notable ARM processors developed by licensees include AppliedMicro X-Gene DEC StrongARM, Freescale i.MX, Marvell (formerly Intel) XScale, Nvidia Tegra, ST-Ericsson Nova and NovaThor, Qualcomm Snapdragon, the Texas Instruments OMAP product line, the Samsung Hummingbird and the Apple A4 and A5.

The ARM architectures used in smartphones, personal digital assistants and other mobile devices range from ARMv5, in obsolete/low-end devices, to the ARM M-series, in current high-end devices. XScale and ARM926 processors are ARMv5TE, and are now more numerous in high-end devices than the StrongARM, ARM9TDMI and ARM7TDMI based ARMv4 processors, but lower-end devices may use older cores with lower licensing costs. ARMv6 processors represented a step up in performance from standard ARMv5 cores, and are used in some cases, but Cortex processors (ARMv7) now provide faster and more power-efficient options than all those prior generations. Cortex-A targets applications processors, as needed by smartphones that formerly used ARM9 or ARM11. Cortex-R targets real-time applications, and Cortex-M targets microcontrollers.

ARMv1 ARM1
ARMv2 ARM2, ARM3
ARMv3 ARM6, ARM7
ARMv4 StrongARM, ARM7TDMI, ARM9TDMI
ARMv5 ARM7EJ, ARM9E, ARM10E, XScale
ARMv6 ARM11
ARMv7 Cortex
ARMv8 No cores available yet. Will support 64-bit addressing

I don't see how this helps with the original question about which ARM based MCU vendor to select.

I try to focus on chip family as more important thing. There is lots of companies with license for ARM, it will take some time to compare all of this.

Have you done any research by yourself? It is difficult for someone to know about all ARM constructors. Furthermore you didn't specify the core. Several different ARM cores exist, are you focusing on something specific? If you are to buy ARM from your local market, then find out about the availability of each company there. About cost, you can easily find that out if you visit an online store for 20 minutes or so. About resources, I think all companies more or less support their products with online documents. Usually people use an MCU architecture and not all of them at the same time. I have used NXP LPC2000 family (ARM7TDMI-S core) and I was satisfied with all the above you asked about.

thank's all
i want to use cortex-m arm mcu
who is the best company
1-st
2-atmel
3-nxp

i think st

Also take a look at freescale's Cortex-M. I 've read many times that it is claimed to be really competitive to NXP and ST.

thank you
but i can't find arm cortex-m in freescale's web site

Kinetis X Series Microcontrollers

When you decide please share your decision with us and the reasons behind this decision, so other people in the future who are searching for the same thing can use this thread as one of their references.

Cheers!

I think that of all companies manufacturing ARM based microcontrollers, ST and NXP are most popular amongst hobbyists. Also worthy of notice are Atmel SAM7 and SAM9 and ARM Stellaris from TI. Definitely st and nxp are most cost effective when purchased in small quantities.

Well you can look at Kinetis or you can have a look into the mid term future, e.g. 2013 for samples and look at Kinetis X. Kinetis devices are available today, low cost tools are low quality, (we ordered 6 and 3 were dead on arrival) but the cube works nicely. Not such low cost though.
Kinetis X has just been announced last week and there is no production any time soon.
Freescale is a new kid on the Cortex-M block but one with very nice devices.

I'll give it a shot.

1. It would be very helpful if you list your requirements, such as memory size, performance, low power needs, analog peripherals, pin count......
All of this has a major impact on the price and where the different vendors are at.

If you don't need HS USB, you might stay clear of Atmel, that's their only valid selling point against other M3/M4 devices. There is lots of focus within Atmel on AVR, more so then on ARM
If you need longest battery life, look at Energy Micro's Gecko families.
If you need highest performance and available now, check out ST and NXP
If you need lowest power during active, check out vendors with Cortex-M0, e.g. NXP and ST but also the M3 from Energy Micro does really well.
If you need the most flexible solution with adaptive pinout and great analog features, check out PSoC 5 from Cypress
If you need something available NOW, check out Digikey for availability ;-)

Are you looking for a small eval board to play with? -> STM32 has the cheapest
Are you looking to do a serious design? -> Don't buy the cheapest

Just realized that I forgot a couple players
If you like TI check out Stellaris. They are neither high performance nor low power, nor low cost. They do provide some excellent reference designs though!
If you like Atmel, well then check them out, for Cortex-M they are neither high performance nor low power don't know the cost.
If you are looking for big embedded memory stop by at Toshiba as well
