ANALOG design Thin Film prints smart sensor label Thin Film Electronics ASA, a pioneer of organic electronics, has announced it has built a temperature-tracking label display using printed organic electronics. The label and display system is intended for tracking the temperature profile of perishable goods. Organic logic detects that a temperature threshold has been exceeded and instructs a display driver to turn on a segmented display. The system makes use of previously announced developments such as the low-voltage Dialog touch chip supports Microsoft, FlatFrog Dialog Semiconductor has announced that its DA8901 multitouch controller IC has met the requirements of Windows 8.1 certification and is the first chip to support touch technology from FlatFrog Laboratories AB (Lund, Sweden). FlatFrog Laboratories AB, founded in 2007 and backed by Intel Capital amongst others, has developed a patented optical in-glass technology that supports multi-touch sensing and can assess how hard someone is touching, based on the spreading of contact surface area. FlatFrog Touch supports up to 40 simultaneous touches with pressure detection and the technology is expected to have applications in mainstream consumer electronics as well as in digital signage, education, automotive, gaming and medical displays. Although optimized to support Microsoft Windows 8.1, the DA8901 is also suitable for use with Android-based touchenabled organic display drivers based on complementary logic, memory write based on temperature threshold, and addressable multibit printed organic memory. Thin Film (Oslo, Norway) said it has now demonstrated all the elements necessary to begin production of system products by the end of 2014. Thin Film operating systems. FlatFrog Touch uses in-glass has been targeting the application in perishable goods for some infrared light, which is injected into the screen and detected time and reckons the temperature monitor market will be worth along the edges. IR light information collected at multiple $3.2 billion in 2020. It includes the monitoring of both food sensors at the edge of the screen can not only detect the and pharmaceuticals in transit, in storage and at retailers. “The precise location of touches but also provide up to 10 bits integration of memory and logic creates an extensible platform, of touch pressure resolution. The system can track multiple on which we will be able to create a wide variety of low-cost touches and gestures and works with multiple objects including electronics in a label format. Printing provides scale and cost gloved hands or a stylus. DA8901 comes in a 5.7mm by advantages that cannot be matched by any other electronic 5.0mm QFN package and is suitable for mounting alongside technology,” said Davor Sutija, CEO of Thinfilm, in a statement. infrared LED emitter and receiver components on a narrow Christer Karlsson, CTO of Thinfilm, added: “A key breakthrough printed circuit board. for this demo was the low-voltage complementary logic we Dialog Semiconductor announced in June of this year. Polyera and our other materials www.dialog.com partners have played an essential role in helping us move products forward.” Thin Film Electronics ASA www.thinfilm.no Programmable frequency translator outputs up to 8 different frequencies, less than 0.3ps jitter IDT’s 8T49N28x family of universal frequency translator devices, the company’s third generation of timing devices is capable of generating eight different output frequencies with less than 300 femtoseconds RMS phase jitter over the standard 12 kHz to 20 MHz integration range, all in one chip. The mixed signal devices offers eight independentlyprogrammable clocking outputs with the flexibility to apply virtually any input frequency and select virtually any output frequency. The 8T49N28x devices are available with one or two PLLs in a single package, depending on the needs of the application. When configured as a frequency synthesizer, the device can use a low-cost, readily-available 10 to 40MHz crystal to produce any frequency from 8kHz to 1.0GHz, regardless of the crystal frequency used. In a frequency translator configuration, the devices accept up to four input reference clocks per PLL from 8 kHz to 875 MHz, switching between them as necessary to generate any output frequency from 8 kHz to 1.0 GHz. These multiple inputs can also be used for redundancy purposes. Each output is individually programmable as LVPECL, LVDS, or as a pair of LVCMOS signals. What’s more, the chip’s integrated fractional output divider has been improved through architectural changes in the analogue domain to be able to generate independent clock frequencies with less than 0.7ps of RMS jitter. For engineers to fully exploit the flexibility of the devices, the company makes available its Timing Commander software. IDT www.idt.com 1A load-switch comes in plastic package Silego Technology Inc., a fabless mixed-signal company has introduced a one-amp dual channel load switch with a 40-milliohm resistance in a 1-mm by 1.6-mm 8-pin standard plastic package, which the company will sell at less than 10 cents per unit in volume The SLG59M1446V is designed to switch power rails at voltages of 1.0 to 5.0V, up to 1A continuous current and 1.5A peak current. Target applications are mobile devices, board-space constrained and battery-powered systems. Although Silego (Santa Clara, Calif.) is fabless, with operations in Taiwan and additional design and technology centers in China, Korea and Ukraine, it has its own copper-FET process, which is claims provides an advantage when applied to sub-micron power switches. The company did not indicate where it is getting CuFET load switches manufactured. Each channel can be configured and enabled independently. This device features a linear voltage ramp even under dynamic loading conditions. The ramp rate on each channel can be independently adjusted using external resistors. The part requires a VDD of 2.5 to 5.25V and has a standby current below 1-microamp. “The CuFET technology allows devices that are both high performance and ultra-small, compatible with standard high reliability plastic packaging.” said Nathan John, Silego’s director of product marketing, in a statement.
