Small motor connectors
ITT Industries, Cannon has released the M3 small motor connector. It is 50% lighter uses simpler harnessing and is completely sealed and shielded.
Designed for motors with a flange size of 60 by 60cm or less, the M3 connector has a high degree of vibration and shock resistance, IP67 sealing, a housing that contains a single power and three feedback insulators separated by metal shielded walls, and two sealed entries for power and feedback cables.

Widening cyberspace
AMD has developed a small form factor motherboard to be used in their new Personal Internet Communicator (PIC) product, developed around featuring AMD’s Geode GX 533@1.1w processor.
The PIC has been developed as part of AMD’s global “50x15” initiative of providing affordable Internet and computing capabilities to 50 percent of the world’s population by the year 2015.
The PIC is designed to be a high-quality, affordable, easy-to-use, robust consumer device that can operate under less than ideal conditions such as inconsistent power voltage, dust and dirt.
General Software designed and developed the BIOS/firmware for the PIC. Embedded firmware is the enabler that can allow a hardware feature to scale across all the operating systems, or an OS capability to scale across all the hardware components.

AT $1.50 (in volume) Actel claims that the latest family of flash based FPGAs, the PROASIC3 and PROASIC3E, are the world’s cheapest.
The low price coupled with the nonvolatility and immediate power on characteristics of flash based technology, mean, Actel hopes, that the PROASIC3 and PROASIC3E will be attractive for consumer, automotive and other price sensitive areas.
The devices have 64 bit, 66 MHz PCI per-
formance, and have on-chip user flash memory. Densities are from 30,000 to 3-million system gates. Actel is also promoting secure in-system programmability as an added benefit of the flash technology. Built-in AES (Advanced Encryption standard) allows the devices to be programmed, either at contract manufacturer or in the field, with an AES encrypted bit-stream.
As well as the unit cost of the part, Actel also claims that, since the flash devices need no other support chips for programming and power management, the overall cost can be half that of an SRAM based device.
The devices are supported by development tools from Actel and third parties, programmers and IP from Actel and third parties.

Chips
Power meter on chip
TDK’S NEW power meter system-on-chip (SOC), the new TDK 71M6511, integrates a 21 bit delta-sigma converter with three sensor chan-
nels, 32-bit compute engine, MCU, RTC, LCD driver, and precision voltage reference. It is targeted at tamper resistant residential time-of-use (TOU) and Pre-payment metering.
Equipped with on-chip digital temperature compensation and TDK's Single Converter Technolog, the device delivers superior linearity over 2000:1 current range, and under adverse environmental conditions. Requiring a single 3.3V capacitive supply circuit, the 71M6511 consumes less than 9 mA in mission and 4 micro Amps in battery backup modes, and it includes 64KB of FLASH, 7KB RAM, Real Time Clock (RTC), 5V LCD boost, 2+ UARTs, and an I2C interface.

Small capacitors |
Bulk metal foil resistor |
AVX’s OxiCap niobium oxide capacitors are now available in smaller and thinner packages for mobile phones, digital cameras and thin notebooks and PDAs. The devices are compatible with the latest lead-free directives, are RoHS compliant and halogen-free.
Niobium oxide capacitors offer a safe failure mode, which means that in the event of critical damage to the device, it will not burn up to the category voltage, meting the requirements of new initiatives designed to eliminate smoke.
OxiCap reliability figures are better than 0.2% per 1000 hours, (2 to 5 times better than comparable polymer products), whilst remaining comparable on temperature stability, frequency response and electrical performance.
Smaller package OxiCap capacitors are available in heights of 1.2, 1.5 and 2.0mm, for height constrained applications such as in wireless cards, clam shell phones, wireless notebooks, slim cameras and single sided board designs. The 0805 package (2.0mm X 1.25mm) is available for space constrained applications.

Vishay has released the VSMP1206 highprecision, surface-mount, Bulk Metal Z-foil resistor. It combines 300 mW power rating, load life stability of 0.01%, and a low nominal TCR of ±0.5 ppm/°C in an industry-stan- dard, surface-mount package.
The use of Bulk Metal Z-foil is claimed to reduce changes in resistance caused by current variation in power resistors and current-sensing resistors with low TCR and thermal resistance, allowing for muchimproved measurement capabilities. Conventional full wrap-around robust terminations ensure safe handling during the manufacturing process and stability during a lifetime of thermal cycles.
The VSMP1206 has a resistance range of 10 W to 30 kW and tight tolerance to ±0.01%. Tighter tolerances are available by request. It is suited for precision analog applications in industrial, medical, military, and airborne end products including metering systems, head-up displays, and electron beam systems.
A voltage divider can be fashioned by using two arbitrarily selected VSMP1206 resistors with a resultant tracking specification of less than 3 ppm/°C, or even below 1 ppm/°C upon request.

Programmable spread spectrum clock oscillator
THE CYPRESS CY25701 is programmable Spread Spectrum Crystal Oscillator (SSXO) with a high-frequency reference crystal in a single package. By integrating frequency synthesis and Spread Spectrum clock functions into the device, the CY25701 runs efficiently with the onboard crystal and eliminates difficult-to-use, higher-order crystals or crystal oscillators, saving time, money and board space.
The clock frequency is programmable from 10 to 166 MHz. To meet regulatory agency
electromagnetic compliance requirements, the programmable Spread Spectrum feature provides a wide range of downor centerspread percentages (0.5 to 4.0%) for maximum EMI reduction. Depending on the application, the CY25701 provides up to 20 dB EMI reduction, based on a worst-case harmonic.
A non-spread, pin-compatible version of the CY25701 will be available in late Q404. The CY25702 enables customers to design in a crystal oscillator with protection in their back pocket. If they should fail EMI testing, the problem can be resolved by simply dropping in the spread spectrum version, CY25701. This ensures flexibility in design, whatever the customers' needs may be.

Open source
IDE from TI
TI has released its first open-source integrated development environment (IDE).
The Code Composer Essentials (CCEssentials) IDE is for the MSP430 family of ultra-low power microcontrollers (MCUs). Based on the Eclipse open source platform, it allows designers and third parties to easily integrate updates and plugins to provide a highly customized and flexible IDE. The CCEssentials IDE was designed to offer an intuitive interface combined with C code density.
Based on the experience from developing IDEs such as like Code Composer Studio (CCStudio) , the CCEssentials IDE features an intuitive interface, one-click debug option, and TI compiler and code generation technology.
The CCEssentials IDE is based on the Eclipse open source development platform. allowing designers the option of using a different host OS, debugger, or compiler based on their preference.
CCEssentials IDE for MSP430 microcontrollers is free and includes an 8K byte C complier and unlimited assembler. CCEssentials Pro IDE features unlimited C and assembly code space for $499.

Online design for sophisticated filters
Nat Semi has announced the WEBENCH Active Filter Designer to speed the creation of sophisticated filters for data acquisition and signal conditioning applications. The tool lets engineers design advanced, highly customised filters for all standard filter types: low pass, high pass, band pass and band stop.
Engineers can sample the amplifiers, download the automatically generated documentation, use the custom assembly diagram and build a filter. They can develop more than 200,000 customised low-pass filters using any of 180 op amps.
A component selection tool rapidly searches the company's portfolio of operational amplifier products (each with hundreds of different electrical parameters) and configures the necessary bill of materials for every design.
WEBENCH Active Filter Designer also contains an embedded expert filter handbook, to guided designers through the process of creating a complete filter solution in a logical step-by- step fashion. All of the advanced theory any engineer would need is provided in a simple, integrated flowchart.
As with all the tools in National's WEBENCH design environment, the Active Filter Designer and its simulators are available free of charge at
