LPRS - New low-power wireless module offers long-range capability

LPRS, one of Europe's leading suppliers of short-range wireless solutions has announced availability of the latest series of wireless modules from Circuit Design. The MU-2-R is an embedded low-power radio modem for transmission of serial data and operates at 434MHz. The new MU-2-R is just 36mm x 26mm x 8mm making it almost half the size of the existing MU-1-R

The MU-2-R wireless module is controlled by simple dedicated commands leaving the user free to concentrate on developing the transmitting and receiving programs for their system. For communication protocols the MU-2-R has a standard protocol and an error correction protocol, which performs error correction on the receiver side. The error correction protocol uses Reed-Solomon code that has strong error correction ability even in environments prone to burst errors. This ensures the user can configure highly reliable systems compared to conventional radio modems.

Transmitting and receiving data and issuing commands employ a UART interface with a single-chip CPU. In addition the module may be controlled via the COM port (RS232C format) of a computer, minimising development times. The MU-2-R is designed to reduce design difficulties involving high frequency components, allowing the user to embed it in their system with peace of mind.

A battery-operated 10mW MU-2-R covers a range of 600 metres or more. If the application requires greater range, the MU-2-R can be used as a relay station without any additional components. For long range applications up to 10 relay stations may be used, making it possible to gather data from and control equipment in remote locations.

Peter Cubbage, sales director, LPRS, said: "The new Circuit Design MU-2-R wireless modules are a welcome addition to our product range and will be particularly useful for security and control systems where low power consumption is required and long data transmission distances are involved. We have a great deal of experience with Circuit Design products and can offer application advice and design support to any of our customers who wish to use this advanced wireless module."

The Reed-Solomon code (RS code) is one of several FEC block codes; it has strong error correction ability and the characteristic of correcting data errors caused by burst noise. Reed-Solomon codes are used in compact disks, satellite communications, and digital TV broadcasting. The MU-2 uses Reed-Solomon code for FEC, which reduces errors occurring due to burst noise and/or noise at low received signal level, and it improves the receive sensitivity of the equipment by more than 5dB

Standard features of the new Circuit Design MU-2-R include R&TTE compliance, low voltage and low consumption current (ideal for battery operated applications), 1:1, 1:N, and N:N systems can be built by flexibly setting link parameters, local access to the status of radio waves and field noise at the target station and source station, standby mode to save the power of systems, field status can be checked in real time using RSSI information in the packet data, a function to lower the output power (antenna power) from 10mW to 1mW is provided for effective use of radio waves. Selectable RF power between 1mW and 10mW allows the user to limit the communication area so that several networks do not interfere with each other.

Typical applications for the new Circuit Design MU-2-R include, serial data transmission, energy monitoring, data monitoring devices, hand-held terminals, barcode reader, housing equipment control, telecontrol, warning systems, remote control for construction machinery, display devices, motor control, lifters, remote control of fire alarm equipment, telemetry, security systems, water level monitors for rivers etc., says the company.

Moto preps 3 touch phones for Motorola Niagara, Fairbanks and Harmony

Believe it or not, there's more to Motorola than just the RAZR and its subsequent successors. In fact, looking at this 2009 roadmap for Verizon Wireless, it looks like Motorola could be selling some pretty hot phones next year. They've got some rather creative names to boot and--get this--they don't all get the "four letters in all caps" naming scheme either. Then again, these could just be codenames and none of them have actually been confirmed by Moto or VZW.

Starting from the left, We have the Motorola RUSH 2. With the increasing popularity in text messaging, instant messaging, and mobile email, we're starting to see more QWERTY dumbphones. The RUSH 2 capitalizes on this trend with a horizontally-sliding QWERTY keyboard and bold black-red color scheme. Look for it in Q1.

In the middle is the Motorola CALGARY, another phone that happens to have a slide-out QWERTY keyboard, but the keys look pretty different. It's almost as if they are laser-etched into a flat piece of aluminum, illuminated with brilliant cyan lighting. From what I can gather, this will also be a touchscreen phone with Sidekick-like tendencies.

Last but not least is the Motorola INFERNO, seemingly an update to the MOTOMING line of Linux smartphones. It looks like it has an active clear flip like the previous MOTOMING phones. Aside from that, we're pretty lacking in details so stay tuned for more as it develops.

It looks like Motorola and Verizon Wireless indeed have big plans for 2009, and those four leaked handsets (Flash, Rush 2, Calgary and Inferno) are not the only surprises prepared by the two companies for next year.

According to BGR, at least other three new phones are scheduled for a 2009 release.

These are Motorola Niagara, Motorola Fairbanks and Motorola Harmony.

None of them seem to be high-end, but the Niagara surely looks good, sporting a slider design that might make it a next-generation RIZR (if Moto wants to continue with the RIZR line, of course).

Here’s what the Motorola Niagara looks like:

Motorola Fairbanks and Motorola Harmony, the other two handsets that Verizon will out sometime next year, are both clamshells. Fairbanks is a rugged PTT one, while Harmony looks like a music-centric device, with touch-sensitive external keys.

ON Semi - Industry’s highest power integrated Power over Ethernet power device

Availability of the NCP1082 and NCP1083, two new members of its POWER over Ethernet (PoE) product family, has been announced by ON Semiconductor.

The NCP1083 joins the NCP1081 as the industry’s highest power integrated Power over Ethernet Power Device (PoE-PD) supporting extended power ranges up to 40W of regulated power delivered to the application load in a 2-pair configuration, says the company.

The NCP1083 is also capable of providing power via an auxiliary parallel supply. Both NCP1082 and NCP1083 fully support the IEEE 802.3af standard and the NCP1083 enables the latest draft IEEE 802.3at (D3.0) standard including two event physical layer classification. Typical applications targeted by NCP1082 and NCP1083 include VoIP phones, WIRELESS access points, industrial Ethernet I/O modules, programmable logic controllers (PLCs), pan-tilt-zoom (PTZ) and dome security cameras, and other applications that require an auxiliary supply.

The NCP1082/3 support normal PoE operation when power is available on the Ethernet cable. In the event Ethernet power is not available, the device accepts an auxiliary supply input to power the application. This approach eliminates the need for a second DC-DC converter and therefore drastically reduces the bill of materials. The new devices support a wide range of external input voltages from 9V to 57V. ON Semiconductor’s integrated NCP1082/3 PoE-PD devices are pin-compatible with the company’s existing NCP1080/1 PoE-PD devices in the TSSOP-EP 20 pin package. Pin compatibility allows the customer to easily mix-and-match different PoE capabilities on different platforms.

The NCP1082/3 exploits ON Semiconductor’s automotive qualified high-voltage SmartPower process to provide superior cable ESD and surge protection levels compared to other integrated PD and DC-DC converter controllers. Low on-resistance (Ron) and extended temperature range from -40C to 85C with full operation up to 150C junction temperature allows the NCP1082/3 to achieve record power levels while operating in harsh environments.

“The auxiliary supply capability facilitates the transition from traditional power sources to Power over Ethernet” said Koen Geirnaert, ON Semiconductor’s PoE-PD product marketing manager. “Combined with the high power capability this feature enables a broad range of applications”

The devices' integrated DC-DC converter controller facilitates the implementation of popular and proven single-ended power supply topologies such as fly-back, buck and forward CONVERTERS for both configurations and uses a control scheme based on peak current control. The controllers have all the features needed for a flexible, robust and highly efficient design, including programmable frequency, slope compensation and soft startup, says the company.

CDMA, UMTS modems gain Linux SDK

Sierra Wireless is shipping a Linux software development kit (SDK) for its 3G wireless modules. The Linux SDK supports its HSPA- and EV-DO Rev-compatible modems, says the company, which also announced it was acquiring embedded wireless vendor Wavecom.

The Sierra Wireless Linux SDK is available to both OEMs and independent software vendors that are developing connection managers for network operators, says the company. The SDK is said to support application development on a wide range of Sierra Wireless adapter products that work with CDMA and UMTS wireless networks, including most recent "AirCard" PC card modems (pictured above), ExpressCard modems (pictured below), "Compass" USB modems, and MCx-class embedded PCI-Express Mini Card modems, such as the MC8792V model shown below. Target applications are said to include portable devices, machine-to-machine (M2M) systems, fixed wireless terminals, vending machines, and fleet management systems, says Sierra Wireless.

The Linux SDK includes a general Application Programming Interface (API), as well as "access to" the Sierra Wireless Command and Status (CnS) API, says Sierra Wireless. The latter includes commands for voice, SMS, and data connections, enabling lower power consumption by comparison with using AT commands, claims the company.

According to a company spokesperson, the Linux SDK has been built, tested, and verified based on Ubuntu- and Debian Sarge-based reference designs. X86 platforms are supported with Ubuntu 8.04, and require 256MB RAM and 3GB of available storage. ARM9 "and other embedded processors" are supported with the Technologic Systems TS-7800 platform, running a Debian Sarge Linux 2.6 distribution, said the Sierra Wireless representative.

The SDK is offered under a "fairly standard" Sierra Wireless license that restricts use to Sierra Wireless products only, and allows for "redistribution with another product that includes the Sierra Wireless product," said the spokesperson. A Linux driver, meanwhile, has already been available as an open source download on kernel.org. Previous Sierra Wireless SDKs have been developed for Windows platforms, including Windows CE and Windows Mobile.

Last week, Vancouver, Canada-based Sierra Wireless announced it had signed an agreement to acquire Paris, France-based Wavecom for 218 million Euros (about $277 million US). Wavecom manufactures embedded wireless technology for M2M applications, strengthening Sierra Wireless's hand in embedded devices while also improving its customer reach in Europe and Asia, says the company.

Stated Trent Punnett, SVP, Marketing and Corporate Development, for Sierra Wireless, "The Linux SDK allows developers integrating Sierra Wireless products into Linux-based systems in a cost-effective way that supports their tight development schedules."

Availability

The Sierra Wireless Linux SDK is available now, free of charge to qualified customers, says the company.

LPRS - Wireless module is 55% smaller and costs less than predecessor

The new MU-2-R embedded RADIO module operates at 434MHz and brings together industrial quality and reliability while having dimensions of just 50mm x 30mm x 9mm it’s only 55% the size of the existing MU-1-R. Manufactured by Circuit Design (CDI), it is now available from LPRS.

The MU-2-R offers 128 RF channels and data speeds up to 4.8kbps with a transmission range from 500 to 700m. The new design is based on an RFIC to ensure very competitive pricing. A number of useful functions are available as standard. These include an RF Test command for evaluating radio environmental conditions at installation site, which allows measurement of received signal strength and floor-noise and packet test measurement of RF communication quality. Transmission POWER may be user selected between 1mW to 10mW to avoid interference with other RF networks. And the new module offers long-range communication from battery power, at 10mW the MU-2-R has a range of greater than 600m. For even greater range additional modules may be installed as relay stations.

”CDI are at the leading edge of short-range radio module design. The new MU-2-R offers more performance in a smaller package and will be ideal for new applications emerging in industrial automation and building control," said Barry Gillibrand, managing director, LPRS. "SRD’s offer price and performance benefits over systems based on Zigbee or Bluetooth and LPRS have the depth of engineering experience to make sure our customers get the best possible WIRELESS solutions in the fastest development time.”

The new CDI MU-2-R offers enhanced error correction by using the Reed-Solomon code has which offers strong data recovery for errors caused by burst noise and can improve the receiver sensitivity by more than 5dB. Reed-Solomon code is also used on CD’s, satellite communications and digital TV broadcasting. With a wide operating temperature range, from –20C to +65C the MU-2-R is ideal for industrial applications.

Typical applications include long-range WIRELESS communications and industrial communications within single buildings or multiple buildings on an industrial site, says the company.

DSM - Small fanless control computer for POS/POI and digital signature applications

With its small dimensions of only 180mm x 180mm x 55mm, the PicoBox from DSM Computer, is seen as the perfect fanless control computer for POS/POI and digital signature applications. The PicoBox augments DSM's embedded systems product line with the high-performance NanoServers and the scalable BookSize PCs for ultra-compact applications, says the company.

The PicoBox is currently available in two variants. The first variant is the PicoBox C2 (96M1611L) model based on the low-POWER Intel Atom N270 processor with a clock frequency of 1.6GHz. The integrated Intel 82945GSE chipset with the Southbridge ICH7M also operates very energy-efficiently. Together they consume only approximately 4.5W. Despite the small power consumption, the Intel Graphics Media Accelerator 950VGA allows the PicoBox C2 to provide good graphic performance. A DVI output is provided as graphical interface.

The second variant is PicoBox C1 (96M1610L) based on the AMD Geode LX800 processor with 500MHz and the AMD CS5536 chip set with internal AMD 2D VGA controller. In contrast to the PicoBox C2, the display is attached using a VGA interface.

Both PicoBox variants offer a dual-LAN interface ideal for use as a client in network applications. Whereas the PicoBox C2 provides GigaBit LAN (2x 1000 Base T) connections, C1 provides two 10/100 Base TX interfaces. If required, WIRELESS LAN 802.11b/g is also supported. In addition to four USB 2.0 ports, two serial outputs and a PS/2 connection (PicoBox C2) or four serial outputs (PicoBox C1) are available. For specific customers, a separate interface panel allows additional external interfaces to be made available.

The high-quality PicoBox housing has space for a 2.5-inch hard disk (Ultra DMA/33/66/100). A USB 2.0 interface allows the external connection of a floppy or a CD/DVD-ROM drive. The CF socket permits the data storage to a Compact Flash.

An external 100VAC to 240VAC 45W power pack, an optional external 8VDC to 30VDC supply or a direct 12VDC input supplies power to the extremely compact embedded system. The operating temperature range is specified as 0C to +50C, says the company.

Intersil - Tiny 10A power module integrates PWM, drivers, MOSFETs and inductor

The development of the ISL8201M, a highly-integrated new POWER conversion module that saves space and cost has been announced by Intersil.

The ISL8201M is a high-EFFICIENCY low-noise, highly-integrated DC-DC power solution in a thermally enhanced QFN package. Included in the package are the PWM controller, MOSFET drivers, power MOSFETs and inductor along with an optimized compensation circuit.

The device simplifies power supply design as only input and output capacitors and a RESISTOR are needed to implement a complete power solution. This small form factor saves considerable board space while the high integration reduces procurement and placement costs in various applications such as telecommunication, data communication, electronic data processing, WIRELESS network systems, medical and instrumentation, and distributed bus architecture based point of load applications. Also, an onboard input filter supports an ultra-low noise operation thus reducing EMI.

The ISL8201M achieves up to 93percent efficiency and 'excellent' thermal performance due to the QFN package that is designed to offer an optimum heat transfer through the PCB. A copper plate under the package allows the ISL8201M to achieve a power density of approximately 200W/in3, roughly four times that of conventional open-frame modules thereby eliminating the need for heat sinks. Other features include internal soft-start, auto-recovery over-current protection, ENABLE pin option and pre-biased output start-up capability.

The ISL8201M's tiny QFM package measures just 15mm x 15mm x 2.5mm, says the company.

Laird - New RF modules push the limits with 2.4GHz radio performance

A new range of proprietary RF modules, providing a new standard of performance for 2.4GHz RADIOs has been announced by Laird Technologies.

The LT2510 is a fifth generation 2.4GHz FHSS module that 'sets the standard' for industrial RF communication. Based on its established proprietary FlexRF technology and operating in the globally available 2.4GHz spectrum, the LT2510 is optimized to outperform conventional WIRELESS standards, says the company.

"Wireless standards always involve a degree of compromise in that they have difficulty meeting extreme levels of performance requirements," said Nick Hunn, advanced technology director, Laird Technologies. "The LT2510 is optimized to deliver outstanding performance in terms of range or POWER consumption, taking it beyond the bounds of the standards-based offerings, while maintaining a competitive cost."

Embedded with Laird Technologies' robust server-client protocol, the LT2510 permits each module to communicate with any other in-range module for true peer-to-peer operation. Modules 'out of range' can be reached via a meshing topology. The configuration and test software enables OEMs to structure and optimize networks to suit their application.

Enhanced API commands provide packet routing control and network intelligence. With its field-proven FHSS air interface protocol, the LT2510 rejects RF noise, excels against multipath scenarios, allows for co-located systems, and provides an extremely reliable communication link.

With over 150Kb/s throughput in half-duplex mode, the LT2510 delivers speedy data rates. In addition, variable output power options (up to one watt) enable communication over distances that are not achievable with competing technologies. A range of ultra-low power modes, plus low TX/RX power consumption, make the LT2510 ideal for power-restrictive or battery-operated applications. The SMT package is well-suited for space-constrained designs and is available in pick-and-place packaging for volume manufacturing, says the company.

TDK - Low-loss high-attenuation compact multilayer filter for 2.4GHz devices

The development and mass-production of a new multilayer bandpass filter for 2.4GHz WIRELESS LAN and Bluetooth devices has been announced by TDK.

The 1.6 x 0.8mm bandpass filter has the same low-loss and high-attenuation characteristics as earlier TDK products but features a profile of just 0.55mm and a near 50% reduction in x-y volume compared to standard 2 x 1.2mm filters. Featuring a High-Q inter-digital resonator, the new design enables the filter to very accurately select the resonating frequency. The 1.6 x 0.8mm filter facilitates high precision system performance and is therefore ideal for use in wireless communications.

The new design of the 1.6 x 0.8mm filter facilitates lower POWER consumption because of its low insertion loss which provides additional system power savings.

The filter has a maximum insertion loss of 2.5dB between 2400MHz and 2500MHz with a minimum attenuation of 40dB between 1920-1980MHz, 25dB from 2110-2170MHz and 30dB from 4800-5000MHz, says the company.

AnalogicTech - High-voltage step-down controller maximizes adapter flexibility

A single-output, step-down controller capable of providing high EFFICIENCY POWER conversion for lower cost 12V adapters, the AAT1185, has been introduced by AnalogicTech.

Fabricated in the company's innovative Modular BCD process, the controller maximizes design versatility by offering both high and low-side pins to drive a wide variety of external N-Channel MOSFETs. Moreover, by supporting both fully synchronous and non-synchronous operation, the device allows designers to develop solutions for such disparate applications as WIRELESS LANs, DSL and cable modems, notebook computers and set-top boxes with a broad range of performance and power efficiency levels.

Given the diversity of 12V adapter applications today, designers need a high degree of flexibility to optimize the solution for their particular system. By providing low- and high-side pins to drive external MOSFETs instead of embedding the MOSFETs directly into the IC, the AAT1185 controller gives designers the option of building lower-cost, non-synchronous solutions using a Schottky diode on the load side switch or building high efficiency synchronous solutions using any of a wide array of power MOSFETs. The AAT1185 single output step-down controller supports a wide 6V to 24V input range. Output voltage is adjustable from 0.8 to 5.5V. Output current ranges from <1a>

The controller provides high- and low-side pins to drive external N-Channel power MOSFETs. Both drive pins are compatible with a wide range of external MOSFETs allowing designers to use the AAT1185 to develop control solutions for both low power and high power configurations.

The AAT1185's constant frequency voltage mode control allows designers to optimize performance across the entire output voltage and load range. A high 490kHz switching frequency helps designers keep external component size small and efficiency high by supporting the use of a wide range of L/C filtering components. External compensation allows the designer to optimize transient response. Shutdown current is <>

To ensure device integrity, the AAT1185 features internal soft start, programmable over-current and over-temperature protection circuits. Qualified across the -40C to +85C temperature range, the AAT1185 is available in a low cost, Pb-free, 14-pin TSOPJW package, says the company.
