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.
It operates over a wide
voltage range of 2.4V - 5.5V. In addition, the SPC122A has a Clock Stop mode for power savings. The power
savings mode saves the RAM contents, but freezes the oscillator, causing all other chip functions to be
inoperative. The Max. CPU clock frequency is 6.0MHz.
(min.) 鈥?6 clock cycles (max.).
It has an Instruction Cycle Rate of 2 clock cycles
The SPC122A includes, not only the latest technology, but also the full
commitment and technical support of Sunplus.
