SPC21A1
20KB SOUND CONTROLLER
GENERAL DESCRIPTION
The SPC21A1 is a CPU based two-channel speech/melody synthesizer including CMOS 8-bit microprocessor
with 69 instructions, 20K-byte ROM for speech and melody data (Speech is compressed by a 4-bit ADPCM with
approx. 6 sec speech duration @ 7KHz sampling rate) and 64-byte working SRAM. It includes two
Timer/Counters, 10 Software Selectable I/Os, and one 8-bit current D/A output. For audio processing, melody
and speech can be mixed into one output. It operates over a wide voltage range of 2.4V - 5.5V and includes
Low Voltage Reset function. The Low Voltage Reset automatically resets when the working voltage is less than
2.2V. In addition, SPC21A1 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.).
The SPC21A1 includes, not only the latest technology, but also the full commitment and technical support of
Sunplus.
