APLUS INTEGRATED CIRCUITS INC. API860G GENERAL DESCRIPTION : API860G is 63 seconds single chip high quality voice synthesizer IC which contains one 4-bit Input port, three 4-bit I/O ports and a 4 bits CPU controller. By programming through the 4 bits CPU controller, user's application includes section combination, trigger mode, control outputs, keyboard matrix and other logic function can be easily implemented. FEATURES : • Single power supply. • Crystal/Ring oscillator option. • 63 seconds voice capacity. • I/O port : 4 I + 12 I / O (But only P1 and P2 can wake up) • Power down mode for saving power consumption. • Reset pin available. • Single ROM for voice program. Maximum 32 K program addressing size available. • Readable ROM data. • One 6 bit timer overflow control is provided. • Two stack for subroutine call. • 5 bits ASPCM synthesis. • 38K Hz modulation for IR transmission. • 15 steps volume control. • Direct Drive/traditional DAC. • 8 bits resolution D/A.
