AT8xC51SND2C/MP3B
The AT8xC51SND2C has been developed for handling MP3 ringing tones in mobile phones and
can replace sound generators while adding SD/MMC card reader, MP3 music decoding, and
connection of the cell phone to a PC through USB. Cell phones can also be used as a thumb
drive extending cell phone capabilities.
The AT8xC51SND2C are fully integrated stand-alone hardwired MPEG I/II-Layer 3 decoder with
a C51 microcontroller core handling data flow, MP3-player control, Stereo Audio DAC and Mono
Audio Power Amplifier for speaker control.
The AT89C51SND2C includes 64K Bytes of Flash memory and allows In-System Programming
through an embedded 4K Bytes of Boot Flash memory.
The AT83SND2C includes 64K Bytes of ROM memory.
The AT8xC51SND2C include 2304 Bytes of RAM memory.
The AT8xC51SND2C provides the necessary features for human interface like timers, keyboard
port, serial or parallel interface (USB, TWI, SPI, IDE), I
face (NAND or NOR Flash, SmartMedia, MultiMedia, DataFlash cards).
The AT8XSND2CMP3B provides also ADC input to the previous configuration. 89SND2CMP3B
includes 64K Bytes of Flash memory. 83SND2CMP3B includes 64K Bytes of ROM memory.
In the following of the document, AT8xC51SND2C refers to the generic product. When named
explicitly, AT8XSND2CMP3B refers to the version with A/D converter.
