INTRODUCTION SNC15030 is a one-channel voice synthesizer IC with PWM direct drive circuit. It built in a 4-bit tiny controller with two 4-bit I/O ports. By programming through the tiny controller in SNC15030, user’s varied applications including voice section combination, key trigger arrangement, output control, and other logic functions can be easily implemented. 2. FEATURES Single power supply 2.4V – 5.5V 30 seconds voice capacity are provided (@6KHZ sample rate) Built in a 4-bit tiny controller I/O Port − Two 4-bit I/O ports P2 and P5 are provided. − The driving/sink current of P2 & P5 is up to 8mA/16mA − The IO pins P2.3 can be modulated with 38.5Khz carry signal to implement IR function. 64*4 bits RAM are provided Maximum 64k program ROM is provided 64K*12 shared ROM for voice data and program Readable ROM code data Built in one channel speech synthesizer Adaptive playing speed from 2.5k-20kHz is provided Built in an PWM circuit output, can directly connected to Speaker for sound output.
