The year 2014 is expected to be a major year for the global semiconductor industry. The industry will and continue to innovate!
Apparently, there are huge expectations from certain segments such as the so-called Internet of Things (IoT) and wearable electronics. There will likely be focus on the connected car. Executives have been stating there could be third parties writing apps that can help cars. Intel expects that technology will be inspiring optimism for healthcare in future. As per a survey, 57 percent of people believe traditional hospitals will be obsolete in the future.
Some other entries from 2013 include Qualcomm, who introduced the Snapdragon 410 chipset with integrated 4G LTE world mode for high-volume smartphones. STMicroelectronics joined ARM mbed project that will enable developers to create smart products with ARM-based industry-leading STM32 microcontrollers and accelerate the Internet of Things.
A look at the industry itself is interesting! The World Semiconductor Trade Statistics Inc. (WSTS) is forecasting the global semiconductor market to be $304 billion in 2013, up 4.4 percent from 2012. The market is expected to recover throughout 2013, driven mainly by double digit growth of Memory product category. By region, all regions except Japan will grow from 2012. Japan market is forecasted to decline from 2012 in US dollar basis due to steep Japanese Yen depreciation compared to 2012.
WSTS estimates that the worldwide semiconductor market is predicted to grow further in 2014 and 2015. According to WSTS, the global semiconductor market is forecasted to be up 4.1 percent to $317 billion in 2014, surpassing historical high of $300 billion registered in 2011. For 2015, it is forecasted to be $328 billion, up 3.4 percent.
All product categories and regions are forecasted to grow positively in each year, with the assumption of macro economy recovery throughout the forecast period. By end market, wireless and automotive are expected to grow faster than total market, while consumer and computer are assumed to remain stagnant.
Now, all of this remains to be seen!
Earlier, while speaking with Dr. Wally Rhines of Mentor, and Jaswinder Ahuja of Cadence, both emphasized the industry’s move to 14/16nm. Xilinx estimates that 28nm will have a very long life. It also shipped the 20nm device in early Nov. 2013.
In a 2013 survey, carried out by KPMG, applications markets identified as most important by at least 55 percent of the respondents were: Mobile technology – 69 percent; Consumer – 66 percent; Computing – 63 percent; Alternative/Renewal Energy – 63 percent; Industrial – 62 percent; Automotive – 60 percent; Medical – 55 percent; Wireline Communications – 55 percent.
Do understand that there is always a line between hope and forecasts, and what the end result actually turns out to be! In the meantime, all of us continue to live with the hope that the global semiconductor will carry on flourishing in the years to come. As Brian Fuller, Cadence, says, ‘the future’s in our hands; let’s not blow it!’
On the growth drivers for GP MCUs, the market growth is driven by faster migration to 32 bit platform. ST has been the first to bring the ARM Cortex based solution, and now targets leadership position on 32bit MCUs. An overview of the STM32 portfolio indicates high-performance MCUs with DSP and FPU up to 608 CoreMark and up to180 MHz/225 DMIPS.
Features of the STM32F4 product lines, specifically, the STM32F429/439, include 180 MHz, 1 to 2-MB Flash and 256-KB SRAM. The low end STM32F401 has features such as 84 MHz, 128-KB to 256-KB Flash and 64-KB SRAM.
The STM32F401 provides thebest balance in performance, power consumption, integration and cost. The STM32F429/439 is providing more resources, more performance and more features. There is close pin-to-pin and software compatibility within the STM32F4
series and STM32 platform.
The STM32 F429-F439 high-performance MCUs with DSP and FPU are:
• World’s highest performance Cortex-M MCU executing from Embedded Flash, Cortex-M4 core with FPU up to 180 MHz/225 DMIPS.

* Image blending (image mixing with some transparency).
• 100 μA typ. in Stop mode.
Some real-life examples of the STM32F4 include the smart watch, where it is the main application controller or sensor hub, the smartphone, tablets and monitors, where it is the sensor hub for MEMS and optical touch, and the industrial/home automation panel, where it is the main application controller. These can also be used in Wi-Fi modules for the Internet of Things (IoT), such as appliances, door cameras, home thermostats, etc.
These offer outstanding dynamic power consumption thanks to ST 90nm process, as well as low leakage current made possible by advanced design technics and architecture (voltage scaling). ST is making a large offering of evaluation boards and Discovery kits. The STM32F4 is also offering new firmware libraries. SEGGER and ST signed an agreement around the emWin graphical stack. The solution is called STemWin.
STMicroelectronics has launched the STM32 F4 series of microcontrollers (MCUs), based on the latest ARM Cortex-M4 core. This adds to the signal-processing capabilities and faster operations to the portfolio of STM32 MCUs.
The STM32 F4 series brings the world’s highest performance Cortex-M microcontrollers at 168 MHz FCPU/210 DMIPS and 363 Coremark score.
Vinay Thapliyal, technical marketing manager-India, Microcontroller Division, Greater China and South Asia region, STMicroelectronics Marketing Pvt Ltd, said that the series extends the ST’M32 portfolio of 250+ compatible devices already in production, including the F1 series, F2 series and ultra-low-power L1 series, respectively. ST is said to have 45 percent of the market share by units.
The STM32 F4 series of MCUs are re-inforced on five pillars:
* Real-time performance — 168MHz/210 DMIPS.
* Outstanding power efficiency.
* Superior and innovative peripherals.
* Maximum integration – 1Mbyte Flash, 192 Kbyte SRAM.
* Extensive tools and hardware — CMSIS DSP library, Matlab support, various IDE starter kits, RTOS and stacks.
A Coremark study says that STM32 F4 gives the best acceleration and highest speed. Thapliyal added, “We are ready for the market.” It takes ART to be #1 in performance: It is a combination of core, embedded Flash design, process, acceleration techniques, etc.
ST’s ART Accelerator, an adaptive real-time memory unleashes the Cortex M4 core’s maximum processing performance equal to 0-wait state execution, and Flash upto 168MHz. Real-time performance is the 32-bit multi AHB bus matrix. The layers are independent of each other.
The STM32 F4 series boasts a high-performance digital signal controller. The MCU leads to the ease of use of C programming, interrupt handling and ultra-low power. The FPU facilitates single precision, ease of use, better code efficiency, faster time to market, eliminates scaling and saturation, and easier support for meta-language tools. The DSP is based on Harvard architecture, single-cycle MAC and barrel shifter.
It also boasts of an outstanding power efficiency. The 230 μA/MHz, 38.6 mA at 168 MHz executing Coremark benchmark from Flash memory (with peripherals off), has been made possible with:
* ST’s 90nm process allowing the CPU core to run at only 1.2 V.
* ART Accelerator reducing the number of accesses to Flash.
* Voltage scaling to optimize performance/power consumption.
* VDD min down to 1.7 V.
* Low-power modes with backup SRAM and RTC support.
The low power in real-life applications is not just low-power mode. There is also a need to consider the percentage of time spend in low-power (LP) mode and in Run mode. If competitors are claiming better low-power modes, these are only an advantage if the overall system is spending more than 90 percent of the time doing nothing in low-power mode.
Superior and innovative peripherals includes, among others, two USB OTGs, two full duplexes PWMs at 168MHz, ADC at 2.4MSPS.
As for maximum integration, the 1-Mbyte Flash and 192-Kbyte SRAM memories available in the product accommodate advanced software stacks and user data, with no need for external memories. The 4-Kbyte SRAM battery back-up is used to save the application state and calibration data (SRAM block used as an EEPROM). In addition, the 528 bytes of OTP memory make it possible to store critical user data, such as the Ethernet MAC addresses or cryptographic keys. Read more…
It is a such a pleasure interacting with Vivek Sharma, VP, Greater China & South Asia-India Operations, and director, India Design Centers, STMicroelectronics. While presenting the latest trends in embedded technologies, he hoped that there could eventually be a fab in India, by 2015. Speaking about ‘More Moore’ and ‘More than Moore’, he talked about 3D heterogeneous integration and smart sensors – that provide new, high-growth opportunities. Sharma largely touched upon smart and green energy.
India’s opportunities to leapfrog are immense, especially with a median age of 25.9 years. As for the Indian consumption context, India’s share is ~3 percent worldwide consumption levels 2009/2010. It is said to be $45 billion or ~3 percent in electronics and $6.7 billion or ~2.5 percent in semiconductor consumption.
Taking a look at leveraging of electronics by nations, (as per 2005 data) Taiwan leads with 15.5 percent of GDP, followed by South Korea at 15.1 percent, China at 12.7 percent, Thailand at 12.4 percent, Germany at 8.3 percent, USA at 5.4 percent, Japan at 4.5 percent, and India at 1.7 percent, respectively.
“More than Moore” diversification has been taking place, especially, by combining SoC and SIP to produce higher value systems.
3D heterogeneous integration has been taking place by integrating multiple functions via 3D/TSV. This involves the vertical stacking and connection of various materials, technologies and functional components together:
* Bio, MEMS and other sensors.
* Digital processing (MCUs, MPUs).
* RF transceivers for data transmission.
* Micro-battery (i.e., thin film).
* Other analog ICs and mixed technologies.
Advantages include integrated multi-functionality, more interconnections, reduced power consumption, smaller packaging, increased yield and reliability, and reduced overall costs.
Smart system integration is another trend, which enables combining “More than Moore” and “More Moore” technologies in a single smart system — from multi-package on board to multi-chip on package.
