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.
