 DESCRIPTION :

aP23682/341/170/085 series high performance Voice OTP is fabricated with Standard CMOS

process with embedded 16M/8M/4M/2M bits EPROM. It can store up to 682/341/170/85 sec voice

message with 4-bits ADPCM compression at 6KHz sampling rate. 16-bits PCM、8-bits PCM and

8-bits ULAW at (4K to 48K sample rate) is also available for user selecting.

User selectable triggering and output signal options provide maximum flexibility to various

applications. Built-in resistor controlled oscillator, 16-bits current mode DAC output and 14-bits PWM

direct speaker driving output minimize the number of external components. PC controlled programmer
