TEA5767 builtin frequency up to 75MHZ digital signal processor, the MD level to achieve 384KBPS/48KHZ high quality MP3 music file playback, plus MP3 player has a generally difficult to match the highfidelity playback line (SNR up to 95DB, THD Total Harmonic Distortion % also very energyefficient. Singlechip puter that is singlechip microputer. By the RAM, ROM, CPU position, timing, counting and multiple interfaces in one of the microcontroller. Its small size, low cost, powerful, widely used in smart industries and industrial automation. The 51 series of microcontrollers is the most typical and most representative one. The curriculum design through its study, the application to achieve the study, design, development software and hardware capabilities. The design of the main design of a microcontroller AT89S52based digital radio calendar. And the LCD screen (12864) shows the corresponding year, month, day, hour, minute, second, week, temperature, radio frequency, signal strength, and radio status, bined with LM386 dualchannel power amplifier of our daily life provide wonderful radio.
