Texas Instruments Incorporated (TI) (NYSE: TXN) today announced a breakthrough generation of ultra-low power MSP430 microcontrollers (MCU), offering the industry's lowest power consumption for devices that can provide up to 25 MHz peak performance, increased Flash and RAM memory and integrated peripherals such as radio frequency (RF), USB, encryption and LCD interfaces. With as low as 160 µA/MHz (microamp per megahertz) active power consumption and 1.5 µA in standby, MSP430F5xx MCUs enable longer battery life and the ability to use smaller batteries for portable applications, or no batteries at all for energy harvesting systems that run off of solar power, vibration energy or human body temperature. For more information, please visit: www.ti****/5xx. TI customer, Jim Vogeley, CEO, AdaptivEnergy, explains that their product, the Joule-Thief™ energy harvester, "collects and stores electrical energy from tiny mechanical vibrations and then uses this harvested energy to power a small, low-power MSP430 MCU. The MCU helps enable a compact RF sensor design to implement ambient intelligence that can detect and report critical conditions in factories, automobiles, offices, homes and other environments, all without wiring or batteries." Increased memory and integrated peripherals like RF, USB, encryption and LCD interfaces allow designers to add functionally needed to advance fields like personal medical, home automation, human interface control, automated meter reading (AMR), portable instrumentation, sensors, consumer electronics and security. Development tools, collateral, third-party support, training and university programs facilitate ease of use and shorten time to market.

PWM is used in many industrial mostly for controlling the motor speed. The PWM is used because its the most efficient method comparing to the analog one. Thats why most of the modern microcontrollers today have this features build in. For more information please visit *******www.ermicro****/blog/?p=224

Curious about connecting a motor to your microcontroller? In this NerdKits video tutorial, we explore motors from an electrical perspective, and see how back EMF, resistive, and inductive considerations lead to the design of a motor control circuit. Finally, we show two demos, one with a motor controlled with a toggled digital output, and the other with pulse width modulation (PWM) to adjust the speed in proportion to the temperature. For more details, source code, and more, see: *******www.nerdkits****/videos/motors_and_microcontrollers_101/

*******www.futureelectronics****/en/Pages/index.aspx During this video, we'll explain what is a Microcontroller as well as how to select the right chip for your application from our line-up of Microcontroller products. A microcontroller is a self-contained system with peripherals, memory and a processor that can be used as an embedded system. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control more devices and processes.

I2C (read as I Square C) bus first introduced by Philips in 1980, because of its simplicity and flexibility the I2C bus has become one of the most important microcontroller bus system used for interfacing various IC-devices with the microcontroller. The I2C bus use only 2 bidirectional data lines for communicating with the microcontroller and the I2C protocol specification can support up to 128 devices attached to the same bus.

This project is engaged to provide flashing lamp simulating a beacon light generally used in shipyards. It is also used in middle of the sea with hidden rocks for warning system. A programmable microcontroller from 8051 family is engaged to provide different intensities at the different times. A low voltage lamp of 12V is driven by a power MOSFET in PWM mode drive which is derived from a microcontroller. The duty cycle of the PWM increases progressively and decreases in certain time interval. Thus the intensity gradually decreases from full intensity to OFF and this process repeats. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.
