| APLUS INTEGRATED CIRCUITS INC. GENERAL DESCRIPTION : API860G 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.
