aP8942A high performance one time programmable chip is fabricated with Standard CMOS process with embedded 1M bits EPROM. It can store up to 42sec voice message with 4bit 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 flexibilitiy to various applications. Built-in resistor comtrolled oscillator, 8-bit current mode D/A output and PWM direct speaker driving output minimize the number of external components. PC controlled programer and developing software are available.
