Sector Address Control Output: This active low output indicates when the
device is nearing the end of the current segment.
Interrupt Output: This active low open drain output goes low whenever the
device reaches the end of a message or the device overflows.When
connected to the interrupt input of the host microcontroller this output can be
used to implement powerful message management options.
External Clock Input: This input can be used to feed the device an external
sample clock instead of using the internal sampling clock. This pin should be
connected to VSSA when not in use.
SPI Clock Input: Data is clocked into the device through the DI pin upon the
rising edge of this clock. Data is clocked out of the part through the DO pin on
the falling edge
Chip Select Input: This active low input selects the device as the currently
active slave on the SPI interface. When this pin is high the device tri-states the
DO pin and ignores data on the DI pin.
Data Input: The DI input pin receives the digital data input from the SPI bus.
Data is clocked on the rising edge of the SCLK input.
Data Output: Data is available after the falling edge of the SCLK input.
Negative Audio Output: This is the negative audio output for playback of
prerecorded messages. This output is usually fed to the negative input of a
differential input power amplifier. The power amplifier drives an external
speaker.
Positive Audio Output: This is the positive audio output for playback of
prerecorded messages. This output is usually fed to the positive input of a
differential input power amplifier. The power amplifier drives an external
speaker.
Reset Input: This active low input clears all internal address registers and
restores the device to its power up defaults.
Single Ended Audio Output: This is the audio output for playback of
pre-recorded messages. This output is usually fed to the input of a power
amplifier for driving an external speaker.
Inverting Analog Input: This input is the inverting input for the analog signal
that the user wishes to record. When the device is used in a differential input
configuration this pin should receive a 16 mV peak-to-peak input coupled
through a 0.1 μF capacitor. When the device is used in a single ended input
onfiguration this input should be tied to VSSA through a 0.1 μF capacitor
Non-Inverting Analog Input: This input is the non-inverting input for the
analog signal that the user wishes to record. When the device is used in a
differential input configuration this pin should receive a 16 mV peak-to-peak
input coupled through a 0.1 uF capacitor. When the device is used in a single
ended input configuration this pin should receive a 32 mV peak-to-peak input
coupled through a 0.1uF capacitor.
