Product Summary
The MSM6585RS 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 MSM6585RS does not include a control circuit to drive an external memory similar to the MSM5205. Therefore, the MSM6585RS can be connected with not only semiconductor memories, but other memory media (CD-ROM, etc.) by the control of CPU.
Parametrics
MSM6585RS absolute maximum ratings: (1)Master clock frequency: 640kHz; (2)Sampling frequency: 4k/8k/16k/32kHz; (3)ADPCM bit length: 4-bit; (4)DA Converter: 12-bit; (5)Low-pass filter: Included (–40dB/oct); (6)Overflow preventing circuit: Included; (7)Power supply voltage: 4.5 to 5.5V; (8)Operating current consumption: 10mA; (9)Operating temperature: –40 to +85℃.
Features
MSM6585RS features: (1)4-bit ADPCM method; (2)Built-in 12-bit DA converter; (3)Built-in low-pass filter (LPF) (–40dB/oct); (4)Sampling frequencies: 4k/8k/16k/32kHz; (5)Master clock frequency (ceramic oscillator): 640kHz; (6)Voice data synthesis: Supported by voice analysis editing tool AR207; (7)Package options: 18-pin plastic DIP (DIP18-P-300-2.54)(MSM6585RS).
