aP89042 aP89021 aP89010 - high performance one time programmable chip is fabricated with Standard CMOS process with embedded 1M/512K/256K bits EPROM. It can store up to 42/21/10 sec voice message with 4 bit ADPCM compression at 6KHz sampling rate. 8 bit PCM is also available as user selectable option. Two trigger modes, simple Key trigger mode and Parallel CPU trigger mode facilitate different user interface. User selectable triggering and output signal options provide maximum flexibility to various applications. Built-in resistor controlled oscillator, 8 bit current mode D/A outpu and PWM direct speaker driving output minimize the number of external components. Pc controlled programmer and developing software are available.
