SNC115 One Channel Direct Drive Speech Controller 1 INTRODUCTION SNC115 is a one-channel voice synthesizer IC with PWM direct drive circuit. It built-in a 4-bit tiny controller with one 4-bit input port, two 4-bit I/O ports. By programming through the tiny controller in SNC115, user’s varied applications including voice section combination, key trigger arrangement, output control, and other logic functions can be easily implemented. 2 FEATURES Single power supply 2.4V – 5.1V 26 seconds voice capacity are provided(@6KHZ sample rate) Built in a 4-bit tiny controller One 4-bit input port, two 4-bit I/O ports are provided 64*4 bits RAM are provided 80K*10 ROM size are provided for voice data and program Maximum 16k program ROM is provided Built in a high quality speech synthesizer Adaptive playing speed from 2.5k-20kHz is provided One voice channel Built in a PWM Direct Drive circuit and a fixed current D/A output System clock : 2MHz Low Power Reset Ver: 1.3 1 June 8, 2005 SNC115 One Channel Direct Drive Speech Controller 3 Block Diagram ROM Program/Speech 80K×10 bits Address Pointers/ STACK SRAM (64 nibbles) Timer ALU Input port 1 Timing Generator OSC Sampling Rate Counter PWM D/A IO port 3 Voice Synthesizer IO port 2 4 PIN ASSIGNMENT Symbol P13 ~ P10 P23 ~ P20 P33 ~ P30 VDD GND RST OSC BUO1/VO BUO2 I/O I I/O I/O P P I I O O Function Description Bit3 ~ Bit0 of Input port 1 Bit3 ~ Bit0 of I/O port 2 Bit3 ~ Bit0 of I/O port 3 Positive power supply Negative power supply Reset pin (active high) Oscillator Input Positive Output of PWM or DA output Negative Output of PWM Ver: 1.3 2 June 8, 2005 SNC115 One Channel Direct Drive Speech Controller 5 FUNCTION DESCRIPTIONS 5.1. Oscillator SNC115 accepts RC type oscillator for system clock. The typical circuit diagram for oscillator is listed as follows. VCC RC Oscillator 5.2. ROM SNC115 contains substantial 80K word (10-bit) internal ROM. Program, voices and other data are shared with this same 80K word ROM. 5.3. RAM SNC115 contains 64 nibble RAM. The 64 nibble RAM is divided into four pages (page 0 to page 3, 16 nibble RAM on each page). In our programming structure, users can easily define and locate RAM page in the program. For instance, users can use the instructions, PAGEn (n=0 to 3) to switch and indicate the RAM page. Besides, users can use direct mode, M0 ~ M15 in the data transfer type instructions, to access all 16 nibbles of each page. 5.4. Power Down Mode “End” instruction will power down SNC115 and enable IC to consume fewer current for power saving. (
