32KB SOUND CONTROLLER
GENERAL DESCRIPTION SPC30A based two-channel speech/melody synthesizer including CMOS 8-bit microprocessor with instructions, 32K-byte speech melody data (Speech compressed 4-bit ADPCM with approx. 9sec speech duration 7KHz sampling rate) 384-byte working SRAM. includes
Timer/Counters, Software Selectable I/Os, audio output. audio processing, melody speech mixed into output. operates over wide voltage range 2.4V 5.5V includes
Voltage Reset function. Voltage Reset automatically resets when working voltage less than 2.2V. addition, SPC30A Clock Stop mode power savings. power savings mode saves contents, freezes oscillator, causing other chip functions inoperative. Max. clock frequency 6.0MHz. Instruction Cycle Rate clock cycles (min.) clock cycles (max.). SPC30A includes, only latest technology, also full commitment technical support Sunplus.
FEATURES 8-bit microprocessor Provides 32K-byte program audio data 384-byte working SRAM Software-based audio processing Wide operating voltage: 2.4V 3.4V@ 4.0MHz 3.6V 5.5V@ 6.0MHz Supports Crystal Resonator Rosc (with Mask option) Max. clock: 4.0MHz 6.0MHz Standby mode (Clock Stop mode) power Savings. Max. 500ns instruction cycle time 4.0MHz clock Provides general I/Os 12-bit timer/counters sources wake-up function Approx.9 speech 7KHz sampling rate with ADPCM audio output (single speaker) Voltage Reset

TIMER/COUNTER SPC30A contains 12-bit timer/counters, respectively. specified timer counter, only used timer. timer mode, re-loaded
counters. When timer overflows from $0FFF $0000, carry signal will make timer automatically reload user's pre-set value up-counted again. same time, carry signal will generate signal corresponding enabled ENABLE Register. specified counter, users reset loading into counter. After counter been activated, value counter

SPEECH MELODY Since SPC30A provides large wide range operation speeds, most suitable speech melody synthesis. frequency. speech synthesis, SPC30A provide accurate sampling
Users record synthesize sound digitize into ROM. sound data
played back sequence control functions designed user's program. Several algorithms recommended high fidelity compression sound including PCM, PCM, ADPCM. melody synthesis, SPC30A provides dual tone mode. Once SPC30A enters dual tone mode, users only need fill either TMB, both tone frequency each channel, count envelope each channel. hardware will toggle tone wave automatically without INT.
