Description

The GPD2846A is an integrated MP3 player IC with FM radio and Line In features with 2W mono amplifie, maximum output 3W @ 5.0V supply (recommendation : 4Ω3W speaker).

Main

Features

1. Support MP3 playback formats.
2. Playable T card / SD card, U disk, FM, and external audio sources (LineIn), inserted after the first broadcast, but also by Mode key switch.
3. Automatically detects the headset is plugged in, and so by the IO port (Mute) Switch the external power amplifier directly, without external transistor.
4. Support the volume size, the number of songs stored on … T card / SD card, U disk, users can save EEPROM
5. It can automatically detect and decide whether an external EEPROM in EEPROM or T card / SD card, U disk, save the settings.
6. In an AD-key port to achieve a variety of button combinations.
7. There are two groups AD-key keyboard to choose from.
8. FM radio chip supports 3: RDA5807, BK1080 and RTC6207E.
9. It does not support infrared remote control,USB device mode nor USB audio mode.
