Overview
SN65031 Two Channels Direct Drive Speech Controller „ INTRODUCTION SN65031 is a 31 seconds two-channel single chip voice synthesizer IC which contains a PWM Direct Drive Circuit and fixed current D/A output.
There are two 4-bit I/O ports and built in a tiny controller.
By programming through the tiny controller, user’s applications including section combination, trigger modes, output status, and other logic functions can be easily implemented.
