aP23085 high performance Voice OTP is fabricated with Standard CMOS process withembedded 2M bit EPROM. It can store up to 85 sec voice message with 4-bit ADPCMcompression at 6K Hz sampling rate. 16-bit PCM and 8-bit PCM is also available as userselectable option. User selectable triggering and output signal options Provide maximumflexibility to various applications.Built-in resistor controlled oscillator, 16-bit current modeDAC output and 14-bit current mode PWM direct speaker driving output minimize the numberof external components.PC controlled programmer and developing software are available.
