INTRODUCTION
SN65061 is a 61 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.
