Atmel Introduces AT89C51SND2C MP3 Decoder for Mobile Phone Applications

The AT89C51SND2C from Atmel Corporation is a new MP3 decoder, which combines in a single package all features needed in a mobile phone to play MP3 ring tones and to convert a cell phone into a pen drive.





The AT89C51SND2C has been specially developed to handle the MP3 ring tones in mobile phones. Integrated in a mobile phone, the AT89C51SND2C can easily replace sound generators, while offering MMC/SD card reader capability, MP3 music decoding and USB connection to PC. This provides mobile phone manufacturers with more functionality while reducing the system size and costs.

Derived from the AT89C51SND1C, a fully integrated standalone hardwired MPEGI/II Layer-3 decoder, with an 8-bit microcontroller core, handling dataflow and MP3-player control, the AT89C51SND2C offers 64 Kbytes of Flash memory, an embedded MP3 decoder, host communication (serial, parallel, USB) and a Multi Media Card interface. It also includes a high quality stereo DAC with a 50 mW earphone power amplifier, and a 500 mW speaker power amplifier.

The AT89C51SND2C can play MP3 music from the mobile phone Flash through UART or SPI or from the Flash card (DataFlash, NAND Flash, MultimediaCard, Xd-Picture Card, Secure Digital, CompactFlash). It can also upload/download files into the mobile phone NAND Flash or NOR Flash, upload files from the MMC to the mobile phone NAND or NOR Flash.

The AT89C51SND2C is available in a BGA100 (9x9mm) package in industrial temperature. Pricing for 500,000-unit quantity per year is US$6.00. A masked ROM version is available for low cost application at US$4.50 for 500,000 units.

A complete development package is available to help designers develop their new applications. It includes an emulator, a development board (AT89DVK-04) and a remote MP3-reference design (AT89RFD-08). All boards come with complete MP3-player firmware, schematics and host drivers.
