GPD2806A Datasheet – IC for Non-screen MP3 Player
User Manual – Non-screen MP3 player applications designed chip
GPD2806A overview
GPD2806A is a chip specially designed for the application of MP3 player without screen card. For different content storage devices, it provides the function of reading SD card and T-flash card and playing MP3. It can also be connected to a PC via USB as a card reader. It can also automatically determine whether there is an external FM receiving chip to determine whether to open the radio function or not.
For the planning of external buttons, GPD2806A operates 3~5 buttons through 3 IO ports, which is convenient for planning of various models and different applications. The biggest feature is that GPD2806A is packaged in SOP16, which can directly push the earphones, and realizes a very cost-effective solution by omitting the crystal oscillator.
