ROHM has developed a USB audio decoder IC that enables audio playback of MP3 files from CD-ROM and USB memory using a single chip, making it ideal for a variety of equipment, including AV receivers, radio players, and stereo component systems.
USB and SD memory cards are receiving increased attention as a storage medium for audio and multimedia files due to their fast read/write speeds, greater convenience, and easier portability compared with CDs and DVDs. Steadily decreasing costs are another reason they are becoming more mainstream. ROHM offers a lineup of single-chip USB audio decoders for different file formats, along with a well-received series for car audio featuring greater ESD resistance.
The BU94702AKV meets market needs by enabling MP3 and CD-ROM playback and USB memory recording on a single chip. Additional features include USB/SD memory card host functionality, MP3/AAC/WMA decoder, FAT file system, and a music search function (file browser) that allows track selection during playback. Also, built-in LDO and DAC circuits enable easy configuration of an audio system by simply connecting a power supply audio amp, and speakers.
Compact and lightweight, the VQFP80 package makes it possible to add audio functionality to a wide range of applications beyond audio-only devices, such as alarm clocks, relaxation products (i.e., massage chairs), electronic dictionaries, and digital cameras.
