MSM6585 - ADPCM Voice Synthesis IC

Datasheet Summary

Description

The MSM6585 is an version-up product of the MSM5205 voice synthesis IC.

Mainly improved points are improvement for the precision of an internal DA converter, a built-in low-pass filter, and expansion on the sampling frequency.

Features

  • 4-bit ADPCM method.
  • Built-in 12-bit DA converter.
  • Built-in low-pass filter (LPF) (.
  • 40dB/oct).
  • Sampling frequencies: 4k/8k/16k/32kHz.
  • Master clock frequency (ceramic oscillator) : 640kHz.
  • Voice data synthesis: Supported by voice analysis editing tool AR207.
  • Package options: 18-pin plastic DIP (DIP18-P-300-2.54) (MSM6585RS) 24-pin plastic SOP (SOP24-P-430-1.27-K) (MSM6585MAZXXX) 30-pin plastic SSOP (SSOP30-P-56-0.65-K) (MSM658.

OKI Semiconductor MSM6585 ADPCM Voice Synthesis IC FEDL6585-02 Issue Date: Jun. 2004 GENERAL DESCRIPTION The MSM6585 is an version-up product of the MSM5205 voice synthesis IC. Mainly improved points are improvement for the precision of an internal DA converter, a built-in low-pass filter, and expansion on the sampling frequency. The MSM6585 does not include a control circuit to drive an external memory similar to the MSM5205. Therefore, the MSM6585 can be connected with not only semiconductor memories, but other memory media (CD-ROM, etc.) by the control of CPU.
