M6585 - MSM6585
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 memor
