1.Overview:
GPD2846A for MP3 player with FM radio function and LineIn features designed chips.

With 2W mono amplifier, power amplifier maximum output 3W 5V supply (recommendation 4 ohm 3W speaker with a small card small speaker on the sound quality is good, sounds great, if that was not enough volume, please directly for 4 Euro 5 watts speaker, loud to scare you, absolutely surprised, hey In other 4 Euro 5 watt speakers, the amplifier chip cooling attention Oh, plus the best heat sink)

2.Main Features:
Support MP3 playback formats.
Playable T card / SD card, U disk, FM, and external audio sources (LineIn), inserted after the first broadcast, but also by Mode key switch.
Automatically detects the headset is plugged in, and so by the IO port (Mute) Switch the external power amplifier directly, without external transistor.
Support the volume size, the number of songs stored on ... T card / SD card, U disk, users can save EEPROM
It can automatically detect and decide whether an external EEPROM in EEPROM or T card / SD card, U disk, save the settings.
In an AD-key port to achieve a variety of button combinations.
There are two groups AD-key keyboard to choose from.
FM radio chip supports 3: RDA5807, BK1080 and RTC6207E.
It does not support infrared remote control.
It does not support USB device mode.
It supports USB audio mode.
Package Type: SOP16 package sheet.

3.Application:
FM radio function MP3 player, no screen mini speaker.

9 IOA3 FMCLK if IOA3 pull-down resistor to ground, IOA3 will output clock signal to the outside
  Hanging FM radio IC. If IOA3 is vacant, FM radio IC will
  Shall take their 32768Hz crystal.
10 IOA2 Mute Mute: Mute the external amplifier to do.
11 DM DM USB of DM.
12 DP DP USB of DP.
13 IOA0 IO-key / LED (1) plug-in LED light: Output "1" represents the lit LED.
                                   (2) as well as IO-key1.
                                   (3) as well as options, are used to define the key mode.
14 IOB1 SD_CLK
              SD_DET
              SD_CLK: clock output T card / SD card.
              SD_DET: detecting whether there is an SD card is inserted, to read "0" on behalf of insertion.
 Please connect a 3.3KΩ resistance Shimoji.
15 IOB0 SD_CMD
   I2C_CLK
   SD_CMD: T card / SD card command and response.
   I2C_CLK: I2C the clock; the external EEPROM, and FM.
16 IOB2 SD_DAT
              I2C_DAT
              SD_DAT: data input T card / SD Card / output.
              I2C_DAT: I2C of data; and external EEPROM FM.

5. AD-key function key operation
(5-1) AD-key a total of S1 ~ S8 total of eight buttons, including four buttons S1 ~ S4 MP3 playback mode (that is, U disk and play
Play SD card / T card) behavior by "IOA0 / LED pin whether the external pull-up resistor" to decide.
Please V33REG pulled through the 22KΩ resistor.
We IOA0 / LED not hang Roption called "key mode a" hang Roption called "key mode two." 

(5-2) Key definitions:
[Prev]: Previous, played on an MP3.
[Next]: Next, play the next MP3.
[P / P]: Play / Pause, play and pause between each switch between the two.
[V +]: Volume +, increase the volume.
[V ++]: Volume ++, long press will continue to increase the volume until you release the button.
[V-]: Volume-, decrease the volume.
[V--]: Volume--, long press will continue to decrease the volume until you release the button.
[Scan]: Scan ALL FM-band, the 87.5MHz ~ 108.0MHz automatic station search once again, and the signal of the radio channels
Storage. Store up to 50 stations.
[Scan +]: 108MHz to search, from the current direction of the channel to search for the closest valid 108MHz radio station, then stopped play
The radio station.
[Scan-]: 87.5MHz to search, from the current direction of the channel to search for the closest valid 87.5MHz radio, then stopped play
The radio station.
[CH +]: Skip to the next (frequency +) saved FM radio stations.
[CH-]: Skips to the previous (frequency -) saved FM radio stations.
[RW]: Rewind, MP3 rewind.
[FF]: Fast Forward, MP3 fast forward.
[Mode]: Mode switching "sequence is SD card / T card U disk FM Line In; Cycle.
In terms of the Mode button to switch to the corresponding mode, playback media mode the correspondence must exist, otherwise it will automatically jump down a mold
formula. For example, after the terms of the Mode button to switch to the Line In Mode, you must insert Line In line role, and if we find
Cut down automatically when a Mode is not inserted.
[Repeat]: In two cycle mode switch, All (the whole song cycle) Single (single cycle)?.
[EQ]: the sound field effect "Normal (normal) Classic (Classic) Bass (bass) Live (live) Rock (Shake
