News and technical information for designers and developers who select microprocessors, microcontrollers, DSPs, and DSCs (digital signal controllers) for embedded designs, as well as developers that specify, generate, test, and maintain software for such systems.

  • Inside the Schick Hydro microcontroller-powered wet razor

    Patrick Mannion, Brand Director, May 16, 2012
    Though the shaving experience may be overrated, a look inside the Schick Hydro reveals another unexpected application for microcontrollers—in this case a less-than-$1 PIC10F222 from Microchip.  More
  • Teardown reveals Chevy Volt's electronic secrets

    Rick DeMeis, Automotive Designline, May 10, 2012
    Beyond battery chemistry and electric propulsion and control, the Chevy Volt enhanced-range electric vehicle builds in flexibility, ruggedness, and diagnostics—with attention to quality construction.  More
  • Generating spatial audio from portable products

    Ken Boyce, Texas Instruments, May 10, 2012
    The ever-shrinking mechanical component of portable devices poses major challenges for stereo audio playback.  More
  • Drive interfaces require trade-offs

    Pallab Chatterjee, Contributing Technical Editor, May 10, 2012
    As the amount of data in networks continues to grow at an exponential rate, higher-performance storage at both the client side and the enterprise server is becoming a necessity.  More
  • Remote display technology lets users fully experience cloud content

    Raj Pawate, Distinguished member, Technical Staff, Texas Instruments Incorporated, May 9, 2012
    The cloud can provide content almost anywhere, anytime. Often, however, the device where the content ends up is not ideal for viewing, sharing and experiencing it. Remote display technology provides an effective path around this dilemma.  More
  • High-performance HF transceiver design: A ham's perspective

    Doug Grant, May 3, 2012
    Designers of equipment for radio amateurs face the same problems as designers of most other systems - squeezing the last dB of performance from off-the-shelf components. Some ingenious designs have evolved, using analog, digital and DSP technology.  More
  • Understanding the basics of setup and hold time

    Deepak Behera, Karthik Rao C.G. and Deepak Mahajan, Freescale Semiconductor, April 19, 2012
    Setup and hold times are treated as intrinsic properties of an element. However, it is the very existence of setup and hold time that often confuses us. Here are the cause of setup and hold time within a sequential element (flip-flop) and a look at the operation of the flop.  More
  • Teardown: The nuances of variable-frequency drives

    Steve Taranovich, Senior Technical Editor, April 19, 2012

  • Design calculations for robust I2C communications

    Chris Parris, Senior Applications Engineer and Jonathan Dillon, Senior Applications Engineer, Memory Products Division, Microchip Technology Inc., April 18, 2012
    The I2C bus topology relies on correctly sized resistance pull-ups for reliable, robust communications. Getting these values wrong can lead to erroneous bus conditions and transmission errors caused by noise or changes in temperature and operating voltages, and by variations between devices.  More
