描述 Description

SNC27332P is a one-channel voice synthesizer IC with 12-bit PWM direct drive circuit.It built in a 4-bit tiny controller with one input port and 24 I/O ports. By programmingthrough the tiny controller in SNC27332P, user’s varied applications including voicesection combination; key trigger arrangement, output control, and other logic functionscan be easily implemented.
