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 :
鈥?Single power supply.
鈥?Crystal/Ring oscillator option.
鈥?63 seconds voice capacity.
鈥?I/O port : 4 I + 12 I / O (But only P1 and P2 can wake up)
鈥?Power down mode for saving power consumption.
鈥?Reset pin available.
鈥?Single ROM for voice program. Maximum 32 K program addressing size available.
鈥?Readable ROM data.
鈥?One 6 bit timer overflow control is provided.
鈥?Two stack for subroutine call.
鈥?5 bits ASPCM synthesis.
鈥?38K Hz modulation for IR transmission.
鈥?15 steps volume control.
鈥?Direct Drive/traditional DAC.
鈥?8 bits resolution D/A.
