SNC27085S中文资料1 CH Speech with noise filter, 12bit PWM output, 8 channel Cap-touch key数据手册Sonix规格书

描述 Description

SNC27085S 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 12I/O ports. By programmingthrough the tiny controller in SNC27085S, user’s varied applications including voicesection combination; key trigger arrangement, output control, and other logic functionscan be easily implemented.
