The uMP3 (µMP3 or "micro MP3") module allows designers to integrate high quality MP3/PCM/WAV/IMA ADPCM playback into designs with an easy to use TTL serial protocol.

Sound files such as voice prompts, sound effects, and music can be played using the µMP3. MP3 playback is CBR (Constant Bit Rate) up to 48 KHz at 192 Kbps, or VBR (Variable Bit Rate) up to 48 KHz at 320 Kbps peak. MP3 files are stored on SD or MMC cards, in a format readable by your PC. PCM (WAV) files and IMA ADPCM files can also be played.

In addition to playing audio files, you can use the µMP3 for your data access applications as well. The µMP3 can create files and store data to MMC and SD cards which can be removed, and read with any standard MMC/SD card reader on a PC. The µMP3 will read SD or MMC cards in either FAT16 or FAT32 formats in any size commercially available (32MB to 2GB and beyond).

Each module has a 1/8" stereo headphone jack for headsets (16 Ohms+) or for line-in connections. The µMP3 also has a multi-function 10-pin connector that allows direct operation of the module using simple logic triggers.

The firmware on the µMP3 is updateable through a bootloader, so you can take advantage of any new features or fixes that may become available for the µMP3.

SD/MMC card not included.

A chipset is also available for people who wish to integrate the uMP3 into their own designs.
