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.

APPLICATION CIRCUIT :
In the following application circuits:
*1 : For heavy loading application, adding an electrolytic capacitor between Vcc and Ground
is recommended.
The recommended value for button cell application is 10F.
*2 : The recommended value for button cell application is 750,or less.
