At one time, the gulf between 16- and 32-bit processors seemed wide and deep, so engineers had a difficult time making the transition from one realm to the other. Many processor manufacturers have helped eliminate that gulf and many development boards and tools simplify the migration between those realms.
Offering current outputs of 300, 350, 500, 600 and 700 mA, RECOM’s RCD-24-x.xx Series LED drivers employ an analog dim-function and a PWM dim-function, which operates in a frequency range from 20 to 200 Hz, with
Multi-processor computers have existed for some time, but only within the last few years have engineers had the opportunity to buy off-the-shelf chips with more than one processor or "core." These devices come in two varieties; symmetrical and asymmetrical. The first group provides multiple "clones" of the same core CPU, thus the term symmetrical. The second group includes devices that put different types of CPUs, DSPs, and accelerators in a system on a chip. I'll concentrate on the former multi-core technologies.
Operating from a minimum input voltage of 1.7 V, Micrel’s MIC531x family of dual LDOs consume total quiescent current of 37 µA while supplying output current of up to 300 mA. The components offer current limit and thermal shutdown protection, PSSR, POR, and voltage scaling while operating in a temperature range from
Using a white LED backlight, OSD Displays’ OSD35GN827A 3.50” diagonal transmissive WVGA TFT includes an integrated resistive touchscreen. The device exhibits an initial typical brightness of 240 cd/m² and a 350:1 contrast ratio in a 78.20 × 65 × 4.35-mm package with an active area of 70.08 × 52.56 mm. The TFT has functions using chip-on-glass technology, which supports a 24-bit SYNC-mode TTL interface that offers
Meeting the Energy Independence and Security Act of 2007, GlobTek’s linear power supplies and transformers present DC or AC outputs up to 20 W/VA, an output voltage range from 3 to 48 VDC and load-specified output in 50 mA increments from 50 mA with ±5% tolerance. The UL94V-0-packaged devices offer thermal and
Exhibiting less than 1% end-to-end resistor tolerance (RTol) error over a ±15-V supply range, Analog Devices' AD529x family of single-channel, 10-bit programmable digital potentiometers (digiPot) offer up to 20 times better performance than similar devices. Available in three versions, the parts offer improved system accuracy in demanding applications such as industrial control systems and medical instrumentation.
Performing with Krystal Bond technology, American Sensor Technologies’ one-piece stainless steel AST20HA pressure transducer has no internal o-rings and exhibits 100-V/m EMI/RFI protection from electrical noise. The CE-approved device offers pressure ranges from 0 to 10,000 psi in compound ranges up to 2500 psi while
Omron Electronics introduced an ultra-small, fixed mount multi-code reader, model V400-R, that automatically recognizes commonly used bar codes and 2D matrix codes. Measuring 58 mm × 46 mm × 24.2 mm, the palm-size metal body reader mounts almost anywhere, and the combination of flexible mounting orientation and front view or side view models gives the V400-R a

“Quad A” may soon become part of the common vernacular. Although the AAAA battery (or Quad A) has been commercially available since 1989, it’s mostly been a niche product, difficult to find on shelves. But with consumer electronics moving towards smaller, more lightweight devices, with decreasing power requirements, the battery industry is adapting. Quad A has long been an internal industry standard for 9 V batteries (6 Quad A’s linked together, each generating 1.5 V, equals 9 V), but it could soon displace the AAA as the battery of choice for portable electronics.
Offering a typical second harmonic of -14 dBc and no sub-harmonic, Crystek’s CVS575S-500 500-MHz voltage controlled surface acoustic wave (SAW) oscillator (VCSO) generates a phase noise level of -135 dBc/Hz at an offset of 10 KHz.
