SNC27P200数据手册Sonix中文资料规格书

描述 Description

SNC27P200 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 SNC27P200, user’s varied applications including voicesection combination; key trigger arrangement, output control, and other logic functionscan be easily implemented.
