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.
