SPC81A1 General Description

The SPC81A1 is a CPU based two-channel speech/melody synthesizer including CMOS 8-bit microprocessor with 69 instructions, 80K-byte ROM for speech and melody data (Speech is compressed by a 4-bit ADPCM with approx. 26 sec speech duration @ 6KHz sampling rate) and 128-byte working SRAM. It includes two Timer/Counters, 20 Software Selectable I/Os, two 8-bit current outputs D/A (or one PWM audio output) and serial interface I/O port. It provides Multi-Duty-Cycle output for remote control purposes. 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, SPC81A1 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 SPC81A1 includes, not only the latest technology, but also the full commitment and technical support of Sunplus.

SPC81A1 Maximum Ratings

Characteristics	Symbol	Ratings
