Wireless USB transceiver aims supports 3-year battery life Cypress Semiconductor says that its ultra-low-power 2.4-GHz WirelessUSB NX transceiver enables three-year battery life for wireless human interface devices, while supporting data rates of up to 2 Mbps, and allowing integration with Cypress’s touch sensing technology. The fourth-generation 2.4-GHz WirelessUSB radio-on-achip enables three years of battery life for wireless mice, keyboards, trackpads, remote controls and other Human Interface Devices (HIDs). End users demand long battery life for wireless HIDs, making a low power consumption radio a must. WirelessUSB NX operates at 900 nA in sleep mode where HIDs spend most of their time, and it offers active current of 12 mA in transmit mode and 15 mA in receive mode. As with other Cypress WirelessUSB families, the NX radio offers superior performance in the presence of common 2.4-GHz interference from sources such as WiFi, Bluetooth, cordless phones and microwaves. WirelessUSB NX is complemented by Cypress’s highly integrated enCoRe VI microcontroller, PSoC 4 system-on-chip devices and complete trackpad modules for touch interfaces, offering manufacturers a single source of supply and support. WirelessUSB NX offers compatibility with common RF devices that are currently designed into wireless HIDs. Compatibility with these solutions enables customers to reuse existing firmware to reduce development time. The Received Signal Strength Indicator feature on WirelessUSB NX supports a 5-bit reading for signal strength and a 4-bit reading for noise strength. Cypress www.cypress.com Plug and play solar generator offers iPod sound The world’s first plug and play electric solar generator has been developed by Solihull & Telford-based AceOn Battery Solar Technology. The generator claims to enable the user to access free electricity on the go and can accommodate up to four plugs with an iPod sound system. As well as powering low energy home lighting and electronic devices – such as TVs, stereos, games consoles, laptops, phones , hair dryers, power tools - the SolarSDS stand-alone energy source is ideal where remote sourced electricity is required and where there is no, or an unreliable, grid network etc. AceOn is in the process of setting up distribution deals around the world and Technical Consultant Neil Turner said: “We envisage that most of our sales will be in Africa, basically where the grid is poor. However we see big opportunities in the middle east due to the vast number of campers who visit the desert weekly as well as servicing our home market in the UK & Europe.” SolarSDS www.solarsds.com 1 kW power supply in a 1U high module Excelsys Technologies’ XSolo family of 1U high, ultra-compact single output power supplies is available in two package types, outputting 504W convection cooled in an open-frame U-channel form-factor and up to 1008W in an enclosed fancooled chassis. Both models carry a 5 year warranty. The XSolo platform offers system integrators a features including; variable fan speed, 12V/300 mA isolated bias supply, remote ON/OFF, output voltage control and parallel operation for higher power applications. Nominal output voltages are 24V and 48V with wide adjustment ranges and user defined set-points. Maximum dimensions are 1U x 238 mm x 128 mm. The XSolo range has dual safety agency certification; EN60950 for industrial applications and EN60601-1 2nd and 3rd Edition for medical applications, fully meeting the stringent creepage and clearance requirements, 4 kVAC isolation and <300 μA leakage current. The XSolo is also compliant with the semiconductor manufacturing standard SEMI F47, fully meeting the voltage dips and interruption requirements, and with all relevant EMC emission and immunity standards. Optional features available include I2C digital control and OR-ing Diodes for N+1 redundancy. Excelsys www.excelsys.com ARM code development package adds runtime analysis Fully integrated with IAR Embedded Workbench for ARM, CRUN is an add-on product that provides developers with accessibility to powerful code analysis The C-RUN runtime analysis product is available as an add-on to the IAR Embedded Workbench for ARM development toolchain. Integrated with the toolchain, C-RUN offers each developer access to runtime analysis. C-RUN is a new product from IAR Systems that performs runtime analysis by monitoring application execution directly within IAR Embedded Workbench. Tight integration with the toolchain supports the full cycle of implementation, testing and debugging. C-RUN for ARM has several features such as bounds checking to ensure accesses to arrays and other objects are within boundaries, different overflow and arithmetic checks, as well as a comprehensive heap checker. Flexible settings enable developers to customise analysis functionality according to specific needs. C-RUN is developed by IAR Systems and introduces code analysis as an early, natural part of the development cycle, the company says, adding that runtime analysis that is both powerful and easy to use is not something that has been readily available to embedded developers. IAR Embedded Workbench for ARM is a high-performance C/C++ compiler and debugger toolchain that incorporates a compiler, an assembler, a linker and a debugger into one complete integrated development environment. C-RUN is an add-on product to version 7.20 of IAR Embedded Workbench for ARM. IAR Systems www.iar.com www.electronics-eetimes.com Electronic Engineering Times Europe June 2014 59
