SN68268

SN68268 Speech Controller INTRODUCTION SN68268 is a 268 seconds single chip voice synthesizer IC which contains I/O pins and a tiny controller. By programming through the tiny controller, user’s applications including section combination, trigger modes, output status, and other logic functions can then be easily implemented. FEATURES Single power supply 2.4V - 5.1V Built in a tiny controller 268 seconds voice capacity are provided Two 4-bit I/O ports and two 4-bit output ports are provided 256*4 bits RAM are provided Maximum 16k program ROM is provided Readable ROM code data Built in a high quality speech synthesizer Adaptive playing speed from 2.5k-20kHz is provided Built in a dual tone melody generator Speech/Dual tone melody mixer is provided Fixed current D/A output is provided to drive external connected transistor for sound output Low Voltage Reset 1 December 20, 2000 SN68268 Speech Controller PIN ASSIGNMENT Symbol P20 P21 P22 P23 P30 P31 P32 P33 P40 P41 P42 P43 P50 P51 P52 P53 VDD OSC TEST RESET GND VO I/O I/O I/O I/O I/O I/O I/O I/O I/O O O O O O O O O I I I I I O Function Description Bit0 of I/O port 2 Bit1 of I/O port 2 Bit2 of I/O port 2 Bit3 of I/O port 2 Bit0 of I/O port 3 Bit1 of I/O port 3 Bit2 of I/O port 3 Bit3 of I/O port 3 Bit0 of output port 4 Bit1 of output port 4 Bit2 of output port 4 Bit3 of output port 4 Bit0 of output port 5 Bit1 of output port 5 Bit2 of output port 5 Bit3 of output port 5 Positive power supply Oscillation component connection pin For testing only Reset pin Negative power supply D/A current output 2 December 20, 2000 SN68268 Speech Controller ABSOLUTE MAXIMUM RATING Items Supply Voltage Input Voltage Operating Temperature Storage Temperature Symbol VDD VIN TOP TSTG Min -0.3 VSS-0.3 -20.0 -55.0 Max 6.0 VDD+0.3 70.0 125.0 Unit.
