SONIX SN67D07

SN67d07
One Channel Direct Drive Speech Controller
„ INTRODUCTION
SN67d07 Series is a 7 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.
