Microcontroller Advances From STMicroelectronics Extend Performance Leadership for Smarter Technology Everywhere

GENEVA -- (Marketwire) -- 02/20/13 -- STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has delivered first samples of a new microcontroller family that combines today's highest performing ARM Cortex-M4 core running at 180MHz and graphics-related enhancements, enabling richer user experiences. Simultaneously, ST is delivering increased software support for embedded graphics development in conjunction with leading vendor SEGGER. ST has also announced full production of a 168MHz series with ultra-large on-chip memory density, which began sampling to lead customers in 2012.

The new 180MHz STM32F429/39 series extends the STM32 family's performance lead among Cortex-M microcontrollers while new production and design techniques have reduced STOP-mode current, enabling longer battery life in portable applications. In addition, the STM32F429/39 has new features such as a TFT-LCD controller, ST Chrom-ART Accelerator™ for faster graphics, and SDRAM interface, allowing user interfaces for applications such as smart meters, small appliances and industrial and healthcare devices to provide richer, more colorful content and more intuitive operation.

I2S TDM (Inter-IC Sound Time Division Multiplex) connectivity allows multi-channel audio designs. Selected devices also have the latest, strongest anti-copying security for embedded processors. The new STemWin graphics software also announced today provides access to the SEGGER emWin embedded graphics stack, and is optimized to take full advantage of these new hardware graphics features.

STemWin is free of charge for STM32 customers, and also includes the SEGGER VNC "Virtual Network Computing" system enabling remote viewing of the user interface using Internet protocols. Additional powerful features for developers include window-manager and widget packages, touchscreen/mouse support, and memory device contexts that allow flicker free screen updates.

"Our STM32 series has established another important new benchmark with the arrival of the STM32F429/39 series," said Michel Buffa, General Manager, Microcontroller Division, STMicroelectronics." We are delighted, also, to complete our work with SEGGER to deliver STemWin for high-quality graphics development. The timing is perfect for our customers to take full advantage of the new STM32F429/39 features."

"We are also entering full production with the STM32F427/37 series first revealed in November 2012," continued Buffa. "These devices deliver high core performance and industry-leading memory density to support feature-rich apps and powerful software environments."

The STM32F429/39 are now sampling to lead customers and are available in the established LQFP100, LQFP144, WLCSP, LQFP176 and UFBGA176 packages. In addition, ST has introduced two new package options with more than 200 pins -- the LQFP208 and TFBGA216 packages that provide extra I/Os allowing designers to maximize the extra performance and functionality of these new devices.

Budgetary pricing is from $7.60 for the STM32F429VGT6 with 1MByte Flash and 256KByte SRAM in LQFP100 package, to $10.23 for the STM32F439BIT6 with 2MByte Flash, 256KByte RAM and crypto/Hash processor in LQFP208 package. All prices are for orders of 10,000 pieces per year.

Further information for technical editors:

The latest 180MHz version of the ARM Cortex-M4 core, featured in the STM32F429/39 series, allows customers currently using a microcontroller and discrete entry-level or mid-range DSP to replace or combine both chips in one digital signal controller based on a standard core. The combination also delivers high energy efficiency and access to the powerful development ecosystem supporting the STM32. The ARM Cortex-M4 core in ST's STM32F4 variants is further enhanced with ST's Adaptive Real-Time (ART) Accelerator. The ART Accelerator achieves zero-wait execution from Flash and achieves 225DMIPS (Dhrystone MIPS) and 606 Coremark (EEMBC Coremark benchmark) scores using industry-standard performance metrics.

By also providing designers with up to 2MByte Flash or 1MByte dual-bank Flash, each with 256KByte RAM -- STM32F429/39 devices allow embedded systems to use sophisticated platforms such as Microsoft® .NET, Java or uC Linux™, whereas embedded designers have historically been limited to a structured language such as C. This approach enables developers to build more feature-rich applications, delivering enhanced user experiences, more quickly and efficiently. Devices with dual-bank Flash permit read-while-write operations which can help protect memory contents, for example by allowing an application to run normally while an update is downloaded to be applied safely at a later time.

In addition, ST has included support for high-speed SDRAM in the device by including an external memory interface for SDRAM modules, thereby offering a cost-effective alternative to SRAM external memories. This latest external memory interface also has a 32-bit wide data bus and operates up to 84MHz.

The enhanced display controller now provided on-chip allows the application to be connected to a standard TFT-LCD while benefiting from the low cost, physical size and real-time effectiveness of a microcontroller-based system. The on-chip TFT-LCD controller features ST's Chrom-ART Accelerator, a hardware block for faster graphics processing, which is capable of doubling pixel-format conversion and transfer throughput compared to running software on the Cortex-M4 core. Developers can also take advantage of typical microcontroller on-chip features such as embedded reset capability and voltage regulators, as well as rich connectivity peripherals and integrated memories. The STM32F429/39 series also delivers freedom from high power consumption, external memory components and the non-deterministic behavior of an operating system, which are typical of MPU-based designs.

By providing state-of-the-art I2S TDM (Inter-IC Sound Time Division Multiplex) digital audio connectivity, the STM32F429/39 supports multi-channel audio designs, whereas earlier microcontrollers have typically supported only the dual-channel I2S standard.

Security and cryptographic capabilities are also enhanced. Whereas STM32F21x and STM32F41x series offered SHA-1 support as part of the hardware cryptographic and hash co-processor, the STM32F437 and STM32F439 now add SHA-2 support as well as AES GCM (AES Galois/Counter Mode) and CCM (Combined Cipher Machine). In addition, the STM32F439 offers advanced memory protection, allowing restricted execution-only access to Flash memory sectors. These new memory-protection features help software-IP providers, customers and silicon providers protect firmware against illegal copying.

Even with the increased core performance, the STM32F429/39 series has low current down to 100µA (typical) in STOP mode. This is around one-third the STOP current of the existing STM32 F2 and STM32 F4 devices, and is achieved through ST's advanced 90nm fabrication process and new design techniques. Customers looking for both high-performance capability in RUN mode and low power in STOP mode now have a solution.

With the STM32F427/37 and STM32F429/39 families at the high end, ST's STM32 microcontroller portfolio extends from entry-level STM32 F0 devices leveraging the Cortex-M0 32-bit core, through ultra low-power, mainstream and high-performance STM32 L1, F1 and F2 variants featuring the Cortex-M3 core, to the latest Cortex-M4 STM32 F3 and F4 mixed-signal and high-performance microcontrollers with DSP and Floating-Point Unit (FPU). All benefit from ST's low-power process technology.

Extensive pin, software and peripheral compatibility among STM32 microcontrollers, and the extensive supporting ecosystem including code samples, design IP, low-cost Discovery kits and third-party development tools, enhance flexibility to scale designs, re-use software and hardware and gain the maximum benefit from investing in the STM32 platform.

The Internet of Things (IoT) is the biggest idea since the creation of the Worldwide Web more than 20 years ago.
Cultural, regulatory, environmental, political and economic (CREPE) conditions over the past decade are creating cross-industry solution spaces that require processes and technologies from both the Internet of Things (IoT), and Data Management and Analytics (DMA). These solution spaces are evolving into Sensor Analytics Ecosystems (SAE) that represent significant new opportunities for organizations of all types. Public Utilities throughout the world, providing electricity, natural gas and water, are pursuing SmartGrid initiatives that represent one of the more mature examples of SAE. We have s...
The security devil is always in the details of the attack: the ones you've endured, the ones you prepare yourself to fend off, and the ones that, you fear, will catch you completely unaware and defenseless. The Internet of Things (IoT) is nothing if not an endless proliferation of details. It's the vision of a world in which continuous Internet connectivity and addressability is embedded into a growing range of human artifacts, into the natural world, and even into our smartphones, appliances, and physical persons. In the IoT vision, every new "thing" - sensor, actuator, data source, data con...
The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...
How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...
An entirely new security model is needed for the Internet of Things, or is it? Can we save some old and tested controls for this new and different environment?

One of the biggest challenges when developing connected devices is identifying user value and delivering it through successful user experiences. In his session at Internet of @ThingsExpo, Mike Kuniavsky, Principal Scientist, Innovation Services at PARC, described an IoT-specific approach to user experience design that combines approaches from interaction design, industrial design and service design to create experiences that go beyond simple connected gadgets to create lasting, multi-device experiences grounded in people's real needs and desires.
Enthusiasm for the Internet of Things has reached an all-time high. In 2013 alone, venture capitalists spent more than $1 billion dollars investing in the IoT space. With "smart" appliances and devices, IoT covers wearable smart devices, cloud services to hardware companies. Nest, a Google company, detects temperatures inside homes and automatically adjusts it by tracking its user's habit. These technologies are quickly developing and with it come challenges such as bridging infrastructure gaps, abiding by privacy concerns and making the concept a reality. These challenges can't be addressed w...
The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...
Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.
Connected devices and the Internet of Things are getting significant momentum in 2014. In his session at Internet of @ThingsExpo, Jim Hunter, Chief Scientist & Technology Evangelist at Greenwave Systems, examined three key elements that together will drive mass adoption of the IoT before the end of 2015. The first element is the recent advent of robust open source protocols (like AllJoyn and WebRTC) that facilitate M2M communication. The second is broad availability of flexible, cost-effective storage designed to handle the massive surge in back-end data in a world where timely analytics is e...
We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...

Explosive growth in connected devices. Enormous amounts of data for collection and analysis. Critical use of data for split-second decision making and actionable information. All three are factors in making the Internet of Things a reality. Yet, any one factor would have an IT organization pondering its infrastructure strategy. How should your organization enhance its IT framework to enable an Internet of Things implementation? In his session at Internet of @ThingsExpo, James Kirkland, Chief Architect for the Internet of Things and Intelligent Systems at Red Hat, described how to revolutioniz...
Bit6 today issued a challenge to the technology community implementing Web Real Time Communication (WebRTC). To leap beyond WebRTC’s significant limitations and fully leverage its underlying value to accelerate innovation, application developers need to consider the entire communications ecosystem.
The definition of IoT is not new, in fact it’s been around for over a decade. What has changed is the public's awareness that the technology we use on a daily basis has caught up on the vision of an always on, always connected world. If you look into the details of what comprises the IoT, you’ll see that it includes everything from cloud computing, Big Data analytics, “Things,” Web communication, applications, network, storage, etc. It is essentially including everything connected online from hardware to software, or as we like to say, it’s an Internet of many different things. The difference ...
