| SN66016B 4-Channel Speech Controller 1 INTRODUCTION SN66016B is a 16 seconds single chip 4-channel voice synthesizer IC that 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 - 5.1V Built in a tiny controller 16 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 52k 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 ( RC-type or Crystal Option) Low Voltage Reset Ver: 1.1 1 December 6, 2004 SN66016B 4-Channel Speech Controller 3 Block Diagram ROM Program/Speech/Melody/Instrument waveform 52Kx12 bits Address Pointers/ STACK SRAM (128 nibbles) Sampling Rate Counter x 4 Timing Generator OSC DA8-bit DA8-bit IO4 IO1 Timer ALU IO2 Voice Synthesizer IO3 4 PIN ASSIGNMENT Symbol P13, P12, P11, P10 P23, P22, P21, P20 P33, P32, P31, P30 P43, P42, P41, P40 VDD GND OSC/XIN XOUT CKSEL I/O Function Description I Bit3 ~ Bit0 of input port 1 I/O Bit3 ~ Bit0 of I/O port 2 I/O Bit3 ~ Bit0 of I/O port 3 O I I I O I Bit3 ~ Bit0 of output port 4 Positive power supply Negative power supply Oscillator / Crystal In Crystal Out Clock type select `L' or floating RC oscillator `H' Crystal D/A current output, for channel 1 and 2 D/A current output, for channel 3 and 4 2 VO1 VO2 O O Ver: 1.1 December 6, 2004 SN66016B 4-Channel Speech Controller 5 FUNCTION DESCRIPTIONS 5.1. Oscillator SN66016B accepts crystal oscillator / ceramic resonator or RC type oscillator (selected by pin CKSEL) for system clock. The typical circuit diagrams for oscillator are listed as follows. VDD VDD 20pf CKSEL OSC/XIN XOUT CKSEL OSC/XIN XOUT 20pf 2MHz Crystal / Resonator RC Oscillator 5.2. ROM SN66016B contains 52K word (12-bit) internal ROM. Program, voices, melodies, data, and instrument waveforms share the same ROM with the others. 5.3. RAM SN66016B contains 128 nibble RAM. The 128 nibble RAM is separated into two pages (page 0 and page 1). An implicit page indicator is utilized to specify page address. Two instructions, PAGE0 and PAGE1, can switch the page indicator. All 64 nibbles of each page can be accessed by direct mode (to specify M0 ~ M63 in the data transfer type instructions.) 5.4. Power Down Mode "End" instruction will let SN66016B enter power down mode and consumer very little amount of current. (<2uA @VDD=3V and <5uA @VDD=5V) After SN66016B enters power down mode, any valid data transition (L H or H L) occurring on any input ports or IO ports (P1, P2, and P3) lead SN66016B back to normal operation mode. Ver: 1.1 3 December 6, 2004 SN66016B 4-Channel Speech Controller 5.5. Sampling Rate Counters 4 independent sampling rate counters are dedicated to 4 individual voice channels to play voices with different playing rates. The playing rate is programmable from 4KHz to 40KHz. The resolution of sampling period of each sampling rate counter is 0.25 uS. This feature helps SN66016B play sounds with accurate pitches in the case of music instrument synthesis. 5.6. Auto repetition Auto repetition function helps SN66016B realize a "looping" sound automatically by hardware without any software effort. equipped with this function. SN66016B. Auto repetition function is a very useful mechanism to implement "Sustain" sound in instrument synthesis. All 4 channels are Arbitrary lengths of looping sound are accepted by 5.7. I/O Ports P1 is a 4-bit input port, P2/P3 are two 4-bit I/O ports and P4 is a 4-bit output port. Any bit of P2 and P3 can be programmed to be input or output individually. Any valid data transition (H L or L H) of P1, P2 and P3 can reactivate the chip when it is in power-down stage.
