| SN66120 4-Channel Speech Controller INTRODUCTION SN66120 is a 120 seconds single chip 4-channel voice synthesizer IC which contains I/O ports and a tiny controller. By programming through the tiny controller, user's applications including section combination, trigger modes, output status, high performance melody, multiple voices, and other logic functions can be implemented. FEATURES Single power supply 2.4V - 5.1V Built in a tiny controller 120 seconds voice capacity are provided One 4-bit input port, two 4-bit I/O ports and one 4-bit output port are provided 128*4 bits RAM are provided Maximum 64k program ROM is provided Readable ROM code data 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 Two 8-bit current output DA converters (Channel 1 + Channel 2 DA1, Channel 3 + Channel 4 DA2 ) System clock: 2M Hz ( R-type or Crystal Option) 1 December 20, 2000 SN66120 4-Channel Speech Controller PIN ASSIGNMENT Symbol P10 P11 P12 P13 P20 P21 P22 P23 P30 P31 P32 P33 P40 P41 P42 P43 VDD GND OSC/XIN XOUT CKSEL I/O I I I I Function Description Bit0 of input port 1 Bit1 of input port 1 Bit2 of input port 1 Bit3 of input port 1 I/O Bit0 of I/O port 2 I/O Bit1 of I/O port 2 I/O Bit2 of I/O port 2 I/O Bit3 of I/O port 2 I/O Bit0 of I/O port 3 I/O Bit1 of I/O port 3 I/O Bit2 of I/O port 3 I/O Bit3 of I/O port 3 O O O O I I I O I Bit0 of output port 3 Bit1 of output port 3 Bit2 of output port 3 Bit3 of output port 3 Positive power supply Negative power supply Oscillator / Crystal In Crystal Out Clock type select `L' RC oscillator `H' Crystal (Internal pull low) D/A current output, for channel 1 and 2 D/A current output, for channel 3 and 4 VO1 VO2 O O 2 December 20, 2000 SN66120 4-Channel Speech Controller ABSOLUTE MAXIMUM RATING Items Supply Voltage Input Voltage Operating Temperature Storage Temperature Symbol VDD-V VIN TOP TSTG Min -0.3 VSS-0.3 -20.0 -55.0 Max 6.0 VDD+0.3 70.0 125.0 Unit.
