aP89341K high performance Voice OTP is fabricated with Standard CMOS process withembedded 8M bits EPROM. It can store up to 341 sec voice message with 4-bit ADPCMcompression at 6KHz 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.
