re: MCU market turns to 32-bits and ARM

I for one welcome the increased volume and lowering of unit costs! I think that as MCU design opportunities continue to expand there will be better solutions using more powerful (and yet cheaper) MCUs. This is a great trend for the designers and system users. I do wonder about the long term profitability factor for the manufacturers, will this help or hurt the industry given the investment needed to bring a MCU to the market? It starts to remind me of the DRAM market as it became a commodity there were repercussions that were felt as the industry matured. Will this happen to the MCU world or is the MCU a "special" breed? Thoughts...?

The growth of 32 bits MCU is primarily driven by tablet, smartphone; or, generally speaking, smart device. The cost sensitive products such as predometer will likely continue using 4/8 bits MCU and some other may shift to 16 bits MCU. Is there any product requiring "bit upgrading" from 16 bits to 32 bits? In which market?

With 32 bit MCU prices diving to the 50cent range they are finding many new markets. This doesn't leave a lot of room for 8 or 16bit parts to compete on price. I think there will be repercussions in the long run as margins continue to get squeezed by the compitition that this commiditization brings.

@robotics developer: There is potential for valueble(profitable) innovations in a few areas: Low power wireless connectivity, Large memory sizes, Analog integration, extreme low power and energy harvesting. And some of this areas have high barriers to entry, meaning less competition. And generally the market is growing. So maybe the focus on microcontrollers will be a bit different, but i still see money flowing.

The data and the article do not align: 16-bit ASP has declined from .71 in 2011 to a projected .53 in 2013. This is in contrast to 8-bit ASP of .65 and 32-bit ASP of 1.53 in 2013. At 41% of the forecasted unit volume, this is driving the ASP erosion.

As devices get smaller it is sometimes more about electric power rather than number of bits. A few microamps saved here and there is important. If i can get 32bits and the power use of 8bits, then I'm interested. As it is, MCUs spend alot of time sleeping, depending on application. Tell me how 32bit MCU sleep state saves me more power......

FWIW numbers below. Looks like all prices drop but 32bit show normal price curve (volume up/price down) while 4/8/16 show just market deterioration (flat volume, accelerating price drop). sales(M$) 2009 2010 2011 2012 2013 4/8bit 4141 5545 4647 4368 4412 16bit 3020 3841 4648 4276 4190 32bit 3956 5780 6422 6524 6916 shipment(M) 4/8bit 4768 6913 5911 6343 6744 16bit 3982 5298 6528 7227 7870 32bit 1131 1818 2451 3700 4457 ASP 4/8bit 0.87 0.80 0.79 0.69 0.65 16bit 0.76 0.72 0.71 0.59 0.53 32bit 3.50 3.18 2.62 1.76 1.55

Wonder if 4-bit and 64-bit could coexist. http://www.embeddedinsights.com/channels/2010/11/24/are-you-or-would-you-consider-using-a-4-bit-microcontroller/

4-bit microcontroller, I never use it. Which field it can be used? in children's toy? Now, more and more project start to use 32-bit MCU, because the embedded linux operating sysyem need to port on it. The performance of 4/8/16 is not enough to support.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
