ROHM has developed a high-resolution Audio SoC "BM94803AEKU" that supports all common audio sources. It also introduces the industry's first audio reference design that supports high resolution.
ROHM, a world-renowned company, has developed a mechanism that can play all common audio sources and control and manage peripheral components and input and output interfaces from traditional recorders, CD stereos, to the latest speakers, USB-DAC and other audio devices. The brain for audio applications) is integrated into a chip that supports the high-resolution*1 Audio SoC*2 "BM94803AEKU". Let's take a look at the related content with Xiaobian.

In recent years, not only high-resolution sound sources, but also various audio devices have become increasingly demanding for faithfully reproducing the amount of information of all sound sources (media, music files).
In order to support all audio sources, not only multiple media decoders such as CDs, USBs, and Bluetooth, including peripheral components, but also software that runs these devices are becoming more and more complicated, so there is a problem that development takes a long time.
ROHM is geared to the audio field. Following the general-purpose IC, audio-related ICs such as sound, speaker amplifiers and media decoders have been developed. This time, the Audio SoC equivalent to the brain was developed and a reference design was provided, which greatly improved the overall sound quality of the sound system and drastically shortened the development cycle.

ROHM, a world-renowned manufacturer, has developed a mechanism that can play all common audio sources and control and manage peripheral components and input and output interfaces from traditional recorders, CD stereos, to the latest Bluetooth speakers, USB-DAC and other audio devices. A brain that can be called an audio application) is integrated into a chip that supports the high-resolution*1 Audio SoC*2 "BM94803AEKU".
"BM94803AEKU" is a product that combines the circuit technology and software technology of ASIC (Special Purpose IC) accumulated by ROHM Group for many years, and various media decoders. It is equipped with SDRAM and integrated on the optimized processor chip. The media decoder not only supports a wide range of audio sources, but also uses ROHM's accumulated technical experience for more than 20 years to achieve playback (scratch CD playback, non-standard USB playback), and miniaturization by mounting SDRAM.
In addition, with the launch of this SoC, the industry's first audio reference design supporting high resolution has also been introduced. The reference design is centered on the Audio SoC and consists of ROHM amplifiers, CD drivers, etc., to maximize the performance of audio equipment and peripheral applications. In addition, special software is provided to help customers quickly develop audio devices that can stably play a large number of audio sources, ensuring the time spent on sound production.
Audio SoC "BM94803AEKU" has been put into mass production for 30,000 yen per month in January 2017 (sample price is 4,000 yen / piece: excluding tax), and a reference design has been launched (reference price 70,000 yen) / Taiwan: excluding tax).
In the future, ROHM will continue to expand its lineup of products supporting high resolution to meet the demands of modern high sound quality.
<new product>
1. Support all common audio sources that users need
Supports traditional media (CD, USB, SD) to new media (smartphone, Bluetooth), PC (USB-DAC connection), and supports many music file formats including FLAC and DSD.
2. Smooth playback of media cherished by users
The new product incorporates ROHM's development experience in ASIC and media decoders for more than 20 years. For example, scratched CDs can also be played without any sound. In addition, non-standard USB memories that exist in many emerging countries can be read. ROHM leverages the know-how accumulated over the years to achieve superior playback stability and meet user expectations for audio equipment.
3. Software with strong support for all audio device development
The Audio SoC, which provides optimized design for audio equipment, and dedicated software that maximizes its performance (provided as a reference design) can significantly shorten the development cycle required by previous audio equipment manufacturers, helping to rapidly develop audio equipment and ensure Sound production time.
4. Equipped with CD- and SDRAM for miniaturization
The Audio SoC is equipped with a CD-DSP (CD media decoder) and 16M bit DRAM (made by LamboS Semiconductor), which were separately installed in the past, for integrated packaging. As a result, the mounting area is smaller and there is no need to worry about radiation between components.
<About Audio Reference Design>
A reference design that maximizes the performance of audio equipment produced by ROHM, centered on the new high-definition Audio SoC.
Not only the audio equipment is installed, but also the peripheral applications (tuner module, Bluetooth module, and CD drive) are installed, and the real machine confirmation of the playback work can be performed immediately. The reference design helps to quickly develop audio devices that support high resolution.
