Description
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 Pro-
gramming 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
2
S output, and all exter-
nal memory interface (NAND or NOR Flash, SmartMedia, MultiMedia, DataFlash cards).
