8-pin Microcontroller Features 3.5 kB Self-Programmable Flash Memory
wtorek, 26 stycznia 2010 09:48

Microchip has announced a new member of its popular 8- and 14-pin PIC16F61X 8-bit PIC® microcontroller family, targeting cost-effective general-purpose applications. The PIC12F617 MCU features 3.5 kB of self-programmable Flash program memory, and peripherals such as a 10-bit Analog-to-Digital Converter (ADC), comparator, Pulse-Width Modulator (PWM) and VREF for closed-loop-control applications—all in a miniature 3 mm x 3 mm DFN package. The new MCU provides an excellent migration path for customers using previous-generation 8-pin PIC MCUs who wish to upgrade to a larger-memory, more peripheral-rich MCU for future designs.

Motorola charges RIM with patent violation
poniedziałek, 25 stycznia 2010 11:05

Motorola Inc. has filed a patent violation complaint against Blackberry maker Research In Motion Ltd. and is asking the U.S. International Trade Commission to initiate an investigation into its mobile handset rival. It also wants a ban on some RIM products already imported into the United States. The Schaumburg, Ill.-based handset and communication gear vendor said RIM infringed upon five of its patents, including in "key technology areas, such as Wi-Fi access, application management, user interface and power management." All the patents are currently being used by RIM, the company said. .

ARM-based processors to take ultra mobile lead in 2013
poniedziałek, 25 stycznia 2010 08:16

ABI Research forecasts that annual ultra mobile device (UMD) shipments based on ARM instruction sets will overtake x86-based UMDs in 2013. The devices will appear in netbooks, MIDs, and UMPCs. While an estimated 90 per cent of UMDs shipped in 2009 were based on an x86 processor architecture, the introduction of ARM-based systems introduces greater choice and differentiation for system vendors, said ABI. “2010 will be pivotal for building momentum behind non-x86 solutions, and gaining adoption in both distribution channels and by end-user populations worldwide,” according to senior analyst Jeff Orr.

Ultra compact LED driver family offers multiple dimming options
czwartek, 21 stycznia 2010 18:52

XP Power announced  the availability of the LDU series of 300 – 1000 mA PCB mount LED drivers. These ultra compact highly efficient devices, measuring just 20.32 x 10.16 x 6.88 mm (0.8 x 0.4 x 0.27 inches) for the LDU08 300 mA model, have a typical efficiency of 95%. Models within the series offer constant current outputs of 300, 350, 500, 600, 700 or 1000 mA. The non-isolated step-down drivers can accommodate a very wide range of input voltage from 7 – 30 VDC. The LDU series suit a broad range of energy efficient LED lighting designs such as those used for advertising displays, traffic signs, automotive lighting and consumer appliances.

Gartner: mobile apps spend to top €4b in 2010
czwartek, 21 stycznia 2010 16:58

Mobile users will spend $6.2 billion (€4b) this year in mobile application stores, compared with global mobile advertising revenues of just $600 million, according to global research firm Gartner. Gartner said that more than $4.2 billion was spent on mobile apps in 2009, with Apple accounting for at least 99.4% of last year’s 2.5 billion mobile apps downloads. The firm predicts that mobile app store downloads will exceed 4.5 billion in 2010 and surpass 21.6 billion by 2013.
