SOUND CONTROLLER
WITH 128KB FLASH MEMORY
1. GENERAL DESCRIPTION
The SPC122A is a two-channel speech/melody synthesizer
including a 8-bit CMOS microprocessor with 69 instructions,
128K-bytes of Flash ROM for speech and melody data (Speech is
compressed by a 4-bit ADPCM with approx. 40 sec speech
duration @ 6KHz sampling rate) and 128-byte working SRAM.
Its external memory is capable of being extended up to 256K. It
provides Multi-Duty-Cycle output that can be implemented for
remote-control
Timer/Counters, 28 Software Selectable I/Os, 2 audio current D/A
outputs (or one PWM audio output), serial interface I/O port, and
volume control are also built in SPC122A. For audio processing,
melody and speech can be mixed into one output. It operates in
a wide voltage range of 2.4V - 5.5V with the maximum clock
speed of 6MHz.
mode for power savings.
RAM contents, but freezes the oscillator to lead all other functions
to standby mode.
