Preliminary SPC122A SOUND CONTROLLER WITH 128KB FLASH MEMORY GENERAL DESCRIPTION The SPC122A is a CPU based two-channel speech/melody synthesizer including CMOS 8-bit microprocessor with 69 instructions, 128K-bytes of Flash ROM for speech and melody data (Speech is compressed by a 4-bit ADPCM with approx. 36 sec speech duration @ 7KHz sampling rate) and 128-byte working SRAM. external memory is capable of being extended up to 256K. Its It provides Multi-Duty-Cycle output that can be implemented for remote-control purposes. It includes two Timer/Counters, 28 Software Selectable I/Os, 2 audio current D/A outputs (or one PWM audio output) and serial interface I/O port. Volume control is also provided. For audio processing, melody and speech can be mixed into one output.
