API860

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.
