1024KB SOUND CONTROLLER
1. GENERAL DESCRIPTION
The SPC1000A is a CPU based two-channel speech/melody
synthesizer including CMOS 8-bit microprocessor with 69
instructions, 1024K-byte ROM for speech and melody data
(Speech is compressed by a 4-bit ADPCM with approx. 340 sec
speech duration @ 6KHz sampling rate) and 128-byte working
SRAM.
with 2 input pins, and two 8-bit current output (D/A). 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 SPC1000A 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. It has an Instruction Cycle
Rate of 2 clock cycles (min.) - 6 clock cycles (max.).
SPC1000A includes, not only the latest technology, but also the
full commitment and technical support of Sunplus.
