ST delivers STM32 connectivity line MCUs

SINGAPORE: STMicroelectronics has confirmed full production availability of its latest STM32 Connectivity Line microcontrollers built on the ARM Cortex-M3 processor, as forecast when the company announced its new devices in March at Embedded World 2009.

The STM32 Connectivity Line allows developers to take advantage of industry-standard 32-bit processing in designs requiring simultaneous Ethernet, USB, CAN and audio-class I2S capabilities.

Two variants are available, including the STM32F105 series combining a Full-Speed USB 2.0 Host/Device/OTG peripheral and two CAN2.0B controllers with advanced filtering capabilities.

The STM32F107 family adds a complete 10/100 Ethernet MAC with hardware support for the IEEE1588 Precise Time Protocol, enabling Ethernet connectivity for real-time applications. Dedicated buffers allow the USB OTG, the two CAN controllers and the Ethernet interfaces to operate simultaneously to satisfy communication-gateway applications, as well as a host of challenges requiring flexible, industry-standard connectivity.

Both families also support audio-class I2S communications which, combined with USB host and SPI capability, allows the micro to read music files from external storage such as a USB mass-storage device, an MP3 player or SD card, and decode and output audio via the I2S. Such features are required in home-audio products such as docking systems, alarm-clock/music players, and home theaters.

The high processing power of the ARM Cortex-M3 allows developers to implement important functions such as the audio codec and human-interface functions such as display-data handling and the Play and Stop buttons in software, thereby saving additional external components.

“Our considerable expertise with ARM Cortex-M3 allows us to quickly introduce new products delivering the advantages of power-efficient operation, solid real-time performance, and innovative shared peripherals to an industry-standard core," said Jim Nicholas, STMicroelectronics Microcontrollers Division Manager. "With four STM32 families in full production, a new ultra-low-power STM32L MCU platform in development, and more innovations planned, our reliable roadmap enables customers to target established markets as well as emerging opportunities.”

The STM32 Connectivity Line comprises 72MHz microcontrollers to fulfill requirements such as network accessibility, data logging, USB connectivity and peripheral extension, or field upgradeability. These requirements will serve products targeting industrial, medical, appliance, consumer, and building-services markets, such as PLCs, motor controls, patient monitors, motor controls, home audio, security systems, power meters and control panels.

A total of 70 STM32 variants are now in production, delivering pin-and-software compatible devices from 36MHz to 72MHz, with a broad selection of common peripherals to serve diverse applications, eight package options and on-chip Flash density from 16Kbyte to 512Kbyte.

The STM32F105 with 64Kbyte, 128Kbyte or 256Kbyte of embedded Flash, and the STM32F107 with 128Kbyte or 256Kbyte, are available immediately in LQFP64 or LQFP100 packages. Prices are from $2.90 in the 64Kbyte LQFP64 package up to $4.92 for 256Kbyte devices in the LQFP100, for quantities of 10,000 units.

10GbE Blade architectures suitable for next-gen data centers

What are some of the critical customer challenges today? For starters, server and storage sprawl increases operational complexity and reduces business predictability. Next, uncontrolled growth has resulted in lack of: space, power and CRAC capacity.

However, it seems that Blade server architectures can alleviate most of data center resource issues. In this context, if customers consolidate, can the network infrastructure optimally sustain the increased workload? And more importantly, what network technology would make sense for the environment?

I recently managed to speak with Adam Mendoza, Senior Manager, OS Alliances, NetApp, and Joel Reich, GM & Sr. Director, SAN/iSAN Business Unit, NetApp.

They attempted to answer these tricky customer pain points, and also touched upon how end-to-end 10GbE Blade architectures could lower IT infrastructure costs, prevent data center equipment sprawl, and help implement consolidation and virtualization.

For the record, recently, members of Blade.org -- BLADE Network Technologies Inc. (BLADE), a leading provider of network switching infrastructure for blade servers; Chelsio Communications (Chelsio), a leading provider of 10GbE network interface cards for servers and storage; and Network Appliance Inc. (NetApp), a leading provider of storage and data management solutions -- completed a collaborative study through Blade.org!

The study demonstrated that blade servers equipped with embedded 10 Gigabit Ethernet (10GbE) networking can support large-scale business applications at near wire-speeds in consolidated blade server architectures using NetApp Ethernet and IP networked storage.

The study, conducted on the IBM BladeCenter platform, found that by supporting multiple protocols, workloads and integrated data management across a 10GbE network, customers can protect their investment, lower IT infrastructure costs, prevent data center equipment sprawl, and implement consolidation and virtualization without sacrificing flexibility. Here's an image that shows this!

Virtualization a powerful trend
Even though virtualization has been doing the rounds for a couple of years now, it has not exactly reached where it should. On the uptake of virtualization by enterprises, Reich said: "What we've seen is probably for virtualization that VMWare is dominant. There's lot of hype around it.

"In reality, virtualization the most important and powerful trend. It is the real big wave of open system computing replacing maniframe applications. People have become smart and got very good at separating hype from real benefit of technology. Virtualization is not quite there as people are using it to consolidate servers, etc., that are running tier 1 applications."

Reich added that people were having big success in consolidating on virtualization in diverse tier 3 applications hosted on Wintel servers. Also, some tier 2 applications were getting consolidated as well. According to him, applications that don't drive critical revenue or manufacturing process would be the tier 3 applications. Tier 2 applications would include small data warehouses, etc.

He explained: "What's going on now is, lot of the introduction of virtualization was in tier 3 applications. It was opportunistic! Customers didn't have to put in lot of architechture thought into tier 3 and tier 2 apps, but they need to do in tier 1 apps. People also need to see what their data centers need to look like, especially when they move to virtualized environment. Silos are purpose-built spaces dedicated to an application in a data center. You need to have specific skill sets to manage those silos."

Blade.org's work
Commenting on Blade.org's work, Mendoza, said: "Effectively, when we first became involved with Blade, the intent was to collectively provide solutions end-to-end. NetApp's one of the few storage companies involved. We came up with a concept of characterizing what business critical applications form across multiple protocols. We need to have all different companies and groups collaborate and get the right experts involved. Blade.org gave us the environment and advantage."

As for the survey itself, they said: "We interviewed over 25 companies -- end users from Fortune 500 and channel partners, VARs, etc. We asked -- if we do this project, what are the things they would want to gain out of it?"

The findings were clear. First, this infrastructure could provide very good performance in this kind of consolidated environment. Second -- there has to be a comparison. "We are comparing networking components of 10GigE agianst fiber channel and utilizing different communications protocols," added Mendoza.

Scoring big with 10GbE
Over the last two yrs, 10GbE, customers have been saying that it is an interesting technology, but they didnt see applicability yet. There's also virtualization. So, if customers bring all this together, where will their bottlenecks be?

Adding the next layer of data management perspective, one of the main concerns of consolidation of this hype would be -- what about data protection, DR implementation, etc.? In this respect, NetApp brings the best kind of software that can handle all of those.

Reich added: "We have over 1,500 blade servers at our North Carolina facility. We learned how to manage that many servers. We take applications, data sets, etc., of blade servers, and save them on to the storage network. When concept customers or development teams say that they need something, we can provide that. We have already had the experience of large-scale dynamic environments. At the end of day, this is all applying to what customers want to see. We are collaborating to provide that to customers."

Another important result of the 10GbE has been an increase in the throughput. Mendoza said they provided the results of running these tests. "We did studies across iSCSI, fiber channel, etc. We are better than 2X in our implementation across 10GE."

So, what can be done to get servers consolidated? How can the data center equipment sprawl be reduced? Reich added: "In virtualization implementations, now, we are talking about a single housing that contains 14 servers. If you start virtualizaing over these 14 servers, you get one footprint. Space wise -- 14 servers come into a 3x2 space. In this manner, we reduced server sprawl, network sprawl and storage sprawl." This also has implications as far as power, cooling, etc., are concerned.

As for the 10GbE aspect, Reich said: "In many cases of a virtualized environment, its important to ask -- what's the new data center that I build will look like? People are also looking for information about how the network infrastructure should look like. Their reason: Ethernet is important as a storage interconnect, and that's because most data centers have two networks -- fiber channel or Ethernet."

So, if you can build something that's going to be ready in two years, can a data center be built that only has one type of network? Both, Reich and Mendoza accept that there's much more work to be do as users really need this kind of information.

"This is just the first step. It is such an important topic that there's a very great need for information," Reich said.

Mendoza added: "Our solution can simplify fabric topology in today's datacenters without compromising reliability? The big question that customers have is: why do we need multiple networks? Fabric refers to the network."

He said: "Part of the reason is simplicity and also economic. The way blade centers are built, you can add different connections to a blade center. The standard configuration of a blade center is the Ethernet. The economic considerations are: you can spend lot less money on blade center infrastructure. The Ethernet is the basic offering. That's part of the reason why, we focused on the 10GbE (Ethernet) from a cost standpoint."

Customers are said to be gaining confidence from the results of the solution development collaboration through Blade.org! Virtualization is the next killer application. It would allow a mixed nature of I/O and CPU utilization, add in standard data protection functions, top it off with application and guest OS management, etc. Customers have also indicated that they have deployed upward of 40 guest OS instances on a single server.

It must be noted that Blade server architectures require the same administrative processes: install, configure, customize, manage, optimize, etc. However, consolidation requires whole new approaches to where the data resides and the speed of access -- both in bandwidth and best practices. The 10GbE Blade architectures are the next-generation data center and are ready for business critical implementations.

Cogs in the wheel

In engineering, it is imperative that all cogs of the wheel come together, so that the wheel rolls smoothly. Similarly, it is imperative that all key IT processes in an organization gel together and work as one.

Imagine the nightmare that enterprises, small and large, would have to go through should this did not happen!

The first basic IT asset is your company's network, or the intranet. We have seen several times that a company's network's down for some reason and mails can't be sent or received.

In such cases, the organizations or the enterprises who are 'stuck' with this situation, are literally crippled. Mails can't be received, mails can't be sent out, important mails are missed, business-critical processes are waylaid, and so on and so forth. I've been part of this nightmare several times.

Once, the undersea cable snapped during my stay in a company. I don't need to add the problem we had to face for at least half a day, as service providers worked furiously to rectify the cable and restore normal service.

Some advocate satellite as the best medium for managing data transmission. Maybe! Some others cite wireless. Perhaps!! Then, I hear from many that there are issues related with security and storage. However, those would only come into play once your basic network is operational smoothly.

In telecom, they have something called five nines, or 99.9999, which means the network is up and running for this percentage of time! You've noticed how people go beserk and start cursing their phones or the network, should they fail to receive a network, or are unable to connect to the network!

What they don't know or realize is the hard work that's involved in setting up, maintaining and operating a network! It's similar to what sometimes happens in offices when the network breaks down and we are unable to send/receive mails.

Maybe, it would be prudent to first manage the internal network as best as possible, before moving on to bigger, better things. The cogs in the wheel got to move smoothly.
