¡iChesen.com¡jAccording to a global statistic, the sales number of car is around 50 ~ 55 millions each year. The semiconductor element number using in the new pattern cars is growing stable these years. There are more than 50 microprocessor units in a car; the electron part is around 20% and growing higher of a car¡¦s main cost. As the global electron industry, like cell phone, PC or digital camera, enter the mature period and lose its high motive power; therefore, the stable automobile industry becomes a new target of many information business, including ST, IBM, NEC, Motorola, etc.
An investigation report for drivers of Car & Drive Magazine, except for the auto-secure shelter, amusement function is the biggest need of automobile electrons. 50 years ago, audio system entered cars and let drivers and passengers can enjoy music in the car.

Through USB OTG main technology, CHESEN OTG-CAR-Elite module platform in the car stereo system can read MP3/WMA music directly from USB storage devices (Pen Drive, Car Reader, MP3 Players, etc.). Under CHESEN File System Management Architecture, original microprocessor system can use serial port to go through Chesen module and read the MP3/WMA music data do the Play/Pause/ Next/ Previous/ Fast Forward/ Fast Backward, etc. functions. Regularly and automatically, the module will send the music play minute/second information to MCU, which keep whole operate system be the same with CD player system.
