Part Number : AP89170, AP89341, AP89085
Function : Voice OTP IC
Manufactures : APLUS INTEGRATED CIRCUITS ( http: //www.aplusinc.com.tw )
aP89341 / AP89170 / 85 series high performance Voice OTP is fabricated with Standard CMOS process with embedded 8M/4M/2M bits EPROM. It can store up to 341/170/85 sec voice massage with 4-bit ADPM compression at 6KHz sampling rate. 8-bit PCM is also available as user selectable option.
Three trigger modes, simple Key trigger mode, Parallel CPU trigger mode and CPU serial command mode, facilitate different user interface. User selectable triggering and output signal options provides maximum flexibility to various applications. Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct speaker driving output minimize the number of external components. PC controlled programmer and developing software are available.
