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.
