 GENERAL DESCRIPTION
The SPC11A, a two-channel speech/melody synthesizer, equips an 8-bit CMOS microprocessor with 69 instructions, 12K-byte ROM for speech and melody data (speech compressed by a 4-bit ADPCM with approx. three seconds speech duration @ 6.0KHz sampling rate) and 64-byte working SRAM. Other primary features include two Timer/Counters, 8 Software Selectable I/Os, and one 8-bit current D/A output. In audio processing, melody and speech can be mixed into one output. It operates at a wide voltage range of 2.4V - 5.5V with a Low Voltage Reset function that automatically resets CPU when operating voltage is less than 1.3V/2.7V. Plus, a Clock Stop mode is built in for power savings.
