MP3/WMA/AAC music decoder from ROHM with USB and SD-card memory interfaces

ROHM has completed the development of the new stand-alone music decoder BU9438KV, featuring the playback of MP3 files as well as WMA and AAC files.

As a new device it enriches the portfolio consisting of BU9428KV (USB entry version), BU9435KV (SD memory access added) and BU9437AKV (WMA decoder added), whilst keeping the pin to pin and software command level compatibility inside this series of ICs. The FF/FW playback features has also been integrated to the new BU9438KV, allowing to move forward or backwards inside a song.

A feature which is appreciated in many applications, ranging from portable music players, car accessories, car radios, home stereo to various other consumer devices.

All mentioned decoders have an integrated system controller, equipped with command software that can perform file searching, reading, decoding, and can switch between standalone and slave operation, minimizing development time. Slave mode allows software control by the microcontroller for complex processes such as filename and ID3 tag display, while standalone mode provides music playback functionality to non-audio applications - even those without a CPU. The BU9438KV enables automatic playback of MP3, WMA and AAC files stored on USB or SD memory, making it ideal for all types of audio devices, such as CD players, compact stereo systems, car audio, and clock radios
