One Channel Direct Drive Speech Controller
„ INTRODUCTION
SN67d03 Series is a 3 seconds one-channel single chip voice synthesizer IC
which contains a PWM Direct Drive Circuit. There are two IO pins (one input,
one IO), which can be configured as two trigger pins, or one trigger and one
output. By filling a coding form, users’ applications, including section
combination, trigger modes, and different output status, can be easily
implemented.
„ FEATURES
Š Single power supply 2.4V – 5.1V
Š 3 seconds voice capacity is provided
Š 1-bit input port (P1) and 1-bit I/O port (P2) are provided
Š 16*1 bits RAM are provided
Š Built in a high quality speech synthesizer
Š Two different playing rate, 6KHz and 8KHz.
Š Built in a PWM Direct Drive circuit output BUO1 and BUO2 directly
connected to Speaker for sound output
Š System clock: 2MHZ
Š Low Voltage Reset
