Overview
SN67d03 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.
