MSM6585
ADPCM Voice Synthesis IC
FEDL6585-03
Issue Date: Aug. 25, 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.
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) (MSM6585MBZXXX)
