Atmel Debuts Ultra Low Power MP3 Decoder for Mobile Phone Applications

10/28/2004 - Atmel® Corporation (Nasdaq: ATML), a global leader in the development and fabrication of advanced semiconductor solutions, announced the availability of the AT89C51SND2C, 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 has versatile functionality apart from generating MP3 tones. It 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.

“For just one dollar more, the AT89C51SND2C allows the mobile phone manufacturers to get rid of the MIDI sound generator while offering to the market a product with extended functionality,” said Bernard Bancelin, Marketing Manager of Audio Line at Atmel. “With its compact package, and low power consumption down to 35 mA while playing music at 2.7V, the AT89C51SND2C offers longer battery life with optimized space,” he added.

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

DAC: Digital -to-Analog Converter
