One Channel Speech Controller

1. INTRODUCTION

SNC15016 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 SNC15016, 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

16 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 34k program ROM is provided

34K*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.

System clock: 2MHz

® Event Mark function supported

® Low Power Detect.

® Watch Dog Timer Supported
