OKI Develops Automotive Audio System LSI, the ''ML673520A''

Enables High-Speed Digital Recording and Three-Track Simultaneous
Play Back
TOKYO--(Business Wire)--
Oki Electric Industry Co., Ltd. (TOKYO:6703) today announced it
has developed the "ML673520A" system LSI for automotive systems. The
chip increases speed of compressing and recording digital audios by
ten-fold and includes a function to playback three tunes
simultaneously.

"The ML673520A is a system LSI based on OKI's strong track record
and skills in designing high-function LSIs. It provides an excellent
solution for automotive systems as the market shifts to digital
audio," said Hiroshi Enomoto, President of Silicon Solutions Company
at OKI. "For nearly 30 years OKI has been offering automotive system
semiconductors for engine control and car navigation systems, and has
been developing LSIs for portable audio players to handle digital
audio data for consumer electronics."

The LSI is suitable for car audio systems and AV-integrated car
navigation systems compatible with digital audio. The LSI includes a
RISC CPU and an audio DSP as well as various communication functions
and is compatible with standards such as USB2.0 host controller, MOST
(Media Oriented System Transport), MediaLB (Media Local Bus) and CAN
controller.

OKI also plans to offer software for drivers and middleware for
configuring audio systems, which will enable users to reduce their
system development time to 70%. Sample shipments of ML673520A are
planned from the end of August 2008 with volume shipments beginning in
December 2008.

-- Major features

1. Enables high-speed (x10) digital recording speed (max)

As DSP technology for audio improves, the speed of compressing and
recording audio data is increased by ten-fold. Leveraging extensive
research, OKI is first in the world to achieve a ten-fold speed for
automotive equipment, enabling users to record a CD onto the HDD of
the navigation system at twice the speed of conventional LSIs.

2. Simultaneously play back up to three songs

The system LSI can simultaneously playback up to three digital
audio files using improved audio DSP technology. Now the driver and
passengers in the front and rear seat can each enjoy different music
at the same time.

Digital audio data is compatible with standards including AAC,
WMA, and MP3. Because the chip uses hardware to control sampling
frequency and convert each type of audio data, it can playback music
efficiently without undue loading of the CPU.

3. Compatible with various storage media

Users can play back music recorded from CDs and other audio data
stored on USB memories and SD cards. In addition, users can store
audio data on a storage media by easily connecting it via USB2.0
(high-speed) host controller, SD card host controller or NAND flash
controller.

4. MOST MediaLB

The LSI includes a MediaLB interface which is compatible to MOST,
the standard that is popular in the European market. The LSI can be
used for various audio applications by using the MOST network.

5. Power Management function

The LSI includes conventional standby-mode as well as functions to
operate and stop by function blocks, enabling low power consumption
operation.
