OKI Launches LSI to Enable Longer Music Playback for Mobiles

Oki Electric Industry announces that it will start volume shipment of a headphone amplifier LSI, the ML2650, from October 2008. This LSI enables battery-powered mobile phones to play back music with low-power consumption, which is achieved by a highly efficient D-class amplifier equipped with a 64KB SRAM that temporarily saves music data. In addition, the LSI comes in an ultra small package size of 2.54 mm x 2.70 mm.

Portable music players and mobile phones with music playback function are becoming complex, requiring CPUs to offer higher performance. However, when using such high-performance CPUs, a complex software process is necessary to reduce power consumption. Therefore, developers have been looking for an easier way to achieve low power consumption in such devices. One way to control power consumption is by pacing operation of the CPU, which is a method to forward music data processed on the CPU to RAM within the device, and put the CPU to rest or standby.

Going forward, OKI will expands its sound LSI product lineup, and develop and sell LSIs that can playback rich sound through various applications.
