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.
FEATURES
Single power supply 2.4V – 5.1V
7 seconds voice capacity is provided
1-bit input port (P1) and 1-bit I/O port (P2) are provided
16*1 bits RAM are provided
Built in a high quality speech synthesizer
Two different playing rate, 6KHz and 8KHz.
Built in a PWM Direct Drive circuit output BUO1 and BUO2 directly
connected to Speaker for sound output
System clock: 2MHZ
Low Voltage Reset
