In your electronic product design's power consumption budget, if the share of power consumed by microcontrorller is higher and important, then naturally you look for selecting a microcontroller consuming as low power as possible without compromising on performance. Example, if you're designing a health monitoring device running on battery, selecting a lowest power consuming microcontroller is necessary. So you may finally start hunting for low-power micrcontrollers in the market.
In some applications microcontroller need to process the data at normal to full capacity only for a short per...
In the previous module we have studied on the electrical properties of audio signal. In the world of digital electronics, the semiconductor logic and processing devices does not compute without digitizing the analog signal. A semiconductor device called analog to digital converter is used to convert linearly varying analog-flow into multi-bit digital binary numbers of where constant output voltage of 5V/3.3V is binary number 1 and zero voltage is binary number 0, representing amplitude quantity of analog signal. To give an example, a 6 volt measuring analog signal can have 8-bit binary out...

Flash memory basics and its interface to a processor:
Introduction:
Flash memory or a flash RAM is a type of nonvolatile semiconductor memory device where stored data exists even when memory device is not electrically powered. It's an improved version of electrically erasable programmable read-only memory (EEPROM). The difference between Flash Memory and EEPROM are, EEPROM erases and rewrite its content one byte at a time or in other words, at byte level. Where as Flash memory erases or...
