SN56060
4-Channel Speech Controller
1. INTRODUCTION
SN56060 is a 60 seconds single chip 4-channel voice synthesizer IC which contains
I/O pins and a tiny controller. By programming through the tiny controller, users’
applications including section combination, trigger modes, output status, high
performance melody, multiple voices, and other logic functions can be implemented.
2. FEATURES
Single power supply 2.4V – 5.5V
Built in a tiny controller
60 seconds voice capacity are provided
128*4 bits RAM are provided
ROM Size
Maximum 184K*10 bits ROM size
64K program ROM is provided
Readable ROM code data
I/O Ports
Four 4-bit I/O ports P1, P2, P3, P6
The driving/sink current of P3.2 & P3.3 are 8mA/16mA
The IO pins P3.3 can be modulated with 38.5Khz carry signal to implement
IR function.
Built in a high quality speech synthesizer
Four independent voice channels
Adaptive playing speed from 4k-40kHz is provided for all 4 channels individually
Automatic repetition for every channel
A 6-bit*8-bit Multiplier is embed to modulate the volume of synthesized voices
Two digital mixers (with saturation control) are provided
Built in an 8-level volume control Analog Push-Pull Direct Drive circuit.
System clock: 2M Hz (RC-type or Crystal Option)
Low Voltage Reset
Built-in WDT function
Built-in Event Mark Function
