Supply Voltage: To minimize noises, the analog and digital
circuits in the ISD4004 devices use separate power
busses. These +3V busses are brought out to separate
pins and should be tied together as close to the supply as
possible. In addition, these supplies should be decoupled
as close to the package as possible.
Row Address Clock: This is an open drain output that
provides the signal of a ROW with a 200 ms period for 8
KHz sampling frequency. (This represents a single row of
memory.) This signal stays HIGH for 175 ms and stays
LOW for 25 ms when it reaches the end of a row.
The RAC pin stays HIGH for 109.37 µsec and stays LOW
for 15.63 µsec in Message Cueing mode (see Message
Cueing section for detailed description). Refer to the AC
Parameters table for RAC timing information at other
sample rates.
When a record command is first initiated, the RAC pin
remains HIGH for an extra T
need of loading the internal sample and hold circuits in the
device. This pin can be used for message management
techniques.
A pull-up resistor is required to connect this pin to other
device.
Interrupt : This is an open drain output pin. This pin goes
LOW and stays LOW when an Overflow (OVF) or End of
Message (EOM) marker is detected. Each operation that
ends with an EOM or OVF will generate an interrupt. The
interrupt will be cleared the next time an SPI cycle is
initiated. The interrupt status can also be read by an R
instruction.
A pull-up resistor is required to connect this pin to other
device.
Overflow Flag (OVF) – The Overflow flag indicates that the
end of memory has been reached during a record or
playback operation.
End of Message (EOM) – The End of Message flag is set
only during playback operation when an EOM is found.
There are eight EOM flag position options per row.
