ROHM's new MP3 encoding and decoding single chip enhances system audio functions

Semiconductor manufacturer ROHM Co., Ltd. launches a USB audio decoder IC that can record MP3 compression or play CD-ROM, USB flash drive audio with a single chip, suitable for various audio devices such as stereo stereos, recorders, AV receivers, etc. ─ BU94702AKV. In the future, ROHM will continue to develop various products with high ease of use based on customer needs, and further commit to expand the series of products.

This new product is scheduled to provide sample shipments starting in July 2011, and has been in mass production with a monthly production capacity of 50,000 since December 2011. The first-stage process is produced by ROHM Co., Ltd., and the rear-stage assembly process is carried out at ROHM Electronics Philippines Co., Ltd. (located in the Philippines).

In response to the file format requirements, ROHM not only launches single-chip USB audio decoder IC series products, but also has a special series of car audio that enhances the resistance to electrostatic damage. After the encoding function is further added to this series of products, there is no need to use a special device, as long as a memory card can simultaneously record music while playing music.

In addition to the built-in USB / SD memory card Host function, MP3 / AAC / WMA decoder function, DAC and FAT file system, the BU94702AKV launched by ROHM this time can perform MP3 compression and CD-ROM as long as a single chip Playback, USB flash drive recording and other functions. Because the product has built-in LDO and DAC circuits, as long as this single chip IC is paired with a power supply, audio amplifier and speaker, an audio system can be easily constructed.

In addition, the product adopts VQFP80 pin small package, which can achieve small and light weight goals. It can add audio functions to a wide range of applications such as alarm clocks, massage chairs and other expressing products, electronic dictionaries, digital cameras and other audio-specific devices. The product is also equipped with convenient functions such as searching tracks during playback.

For the 132kV Oil Immersed Power Transformer, we can produce capacity upto 180MVA. We use the best quality of raw material and advance design software to provide low noise, low losses, low partial discharge and high short-circuit impedance for power transformer.

Our power transformer are widely used in national grid, city grid, rural grid, power plant, industrial and mining enterprise, and petrochemical industry.
