MP3 decoding chip list

P3 is mainly composed of storage chip and decoding solution (chip)!

Decoding solution:
The solution (decoding chip) is divided into single chip and dual chip. Single chip refers to the chip in which the control part and MP3 decoding operation part are integrated into one integrated circuit. Dual chip means that the control part is one integrated circuit and the MP3 decoding operation part is another integrated circuit. Typical is Philips.
The solutions are mainly from the following manufacturers:
Philips: SAA7750 /SAA7751 /PNX0101ET
has good sound quality, powerful functions and stability, and is the first choice for high-end machines
. In addition to the decoding chip, a control chip is also required, which is costly. It has MP3 encoding function.
The bass volume is sufficient, the mid-range performance is excellent, and the treble is average.

Sigmatel: STMP3410/1342/3420/3520
3420 is based on 3410, with MP3 encoding function added
3520 is based on this, with USB2.0 function and reduced power consumption
Sigmatel is the most widely used and mature solution
The sound is brighter. The sound quality is quite satisfactory, and the performance of human voice and musical instruments is quite good
Since many development companies are engaged in the development of this chip, more and more functions can be done at present, including electronic pictures, lyrics synchronization, TXT reading, alarm clock, etc. However, since some of its programs are placed on flash, it is easy to lose the program Ji


Li: 2075 and 2085 ATJ2089/2087 (mostly used in high-end machines)
2075 and 2085 are the most used in domestic low-end machines
. 2085 has more USB2.0 support than 2075.
It integrates MP3 playback, flash disk function, support for DVR format files, AB repeat, and LCD display function.
The sound quality is comparable to Sigmatel. The early repair rate was higher, but it is much more mature now.

Sunplus (Lingyang): SPCA514A/SPCA751A
is cheap, and is used by many low-end domestic machines. The sound quality is average, and the repair rate is low.

Samsung: S3C2410

telechip: TCC730/TCC731
is from South Korea, and the function, performance, and sound quality are better than SIGMATEL chips. Sufficient
bass volume, balanced frequency bands, and wide sound field
. The sound quality is OK.
SKYLARK: From South Korea's ECT company: It is used by domestic button machines, but it does not support WMA at present.

MosArt (Huasi): The lowest-end solution on the market, cheap, simple functions, and poor sound quality.

In addition to the above, there are some less used ones, such as: Atmel, Taiwan ACCFAST, Zhuhai Keguang, Winbond, etc.

Storage chip:
Samsung: The quality and compatibility are the best
. Hyundai: The best price-performance ratio, slightly inferior quality.
Toshiba: Good quality, average compatibility
