Oki Announced a ML696500 Series System For HDD-Based Audio Players

Oki announced that it has succeeded in developing two ARM946E-S-core system LSIs, the ML696500 series, using a single chip to realize the major component functions of hard disk drive (HDD) audio players.

The ML696500 series introduced is an LSI intended for HDD audio players. It enables MP3 and WMA audio files to be played, as well as high-speed data transfer between PC and the player's hard drive. It comes in two models; either with an onboard 512 KB Flash ROM; the ML69Q6500, or without; the ML696500.

Since both ML696500 and ML69Q6500 models have onboard USB 2.0 high-speed device controllers and Ultra DMA 66-compatible ATA/IDE controllers, a dramatic increase in data transfer speed between PC and player has been achieved; with a current effective data transfer rate of 128 Mbps, compared to that of 8 Mbps for USB 1.1 full-speed controllers.

Furthermore, the ML696500 series has simplified the design of complex analog circuitry by combining primary audio-player component functions onto a single chip. Previously, components such as the DA converter, mounted with a headphone amplifier, AD converter mounted with a microphone amplifier required several chips.
