Playback stability and miniaturization achieved through an integrated chip

ROHM has developed an audio SoC capable of playing not only existing media devices but also new media audio sources.



The new BM94803AEKU integrates the "brain" of audio applications into a single unit, supporting not only existing media such as CD, USB, and SD, but also connections via smartphones, Bluetooth, and USB-DAC. Furthermore, it supports a wide range of music file formats, including FLAC and DSD.



The BM94803AEKU provides playback stability through circuit and software technologies such as ASICs, microcontrollers, and various media decoders. Therefore, even CDs with scratches on the surface can be played smoothly without skipping, and it is also compatible with non-standard USB memory sticks from emerging countries.

This audio SoC incorporates a CD media decoder and SDRAM, which were previously mounted as separate devices, into a single package. As a result, not only is the mounting area reduced, but concerns about radiation noise between devices are also reduced.
