2 FUNCTIONAL DESCRIPTION
The ISD5116 is a single chip solution for voice and analog storage that also includes the capability to
store digital information in the memory array. The array may be divided between analog and digital
storage, as the user chooses, when configuring the device. The device consists of several sections that
will be described in the following paragraphs.
Looking at the block diagram below, one can see that the ISD5116 may be very easily designed into a
cellular phone. Placing the device between the microphone and the existing voice encoder chip takes
care of the transmit path. The ANA IN is connected between one of the speaker leads on the voice
decoder chip and the speaker is connected to the SPEAKER pins of the ISD5116. Two pins are needed
for the I
2
C digital control and digital information for storage.
Starting at the MICROPHONE inputs, the signal from the microphone can be routed directly through the
chip to the ANA OUT pins through a 6 dB amplifier stage. Or, the signal can be passed through the AGC
amplifier and directed to the ANA OUT pins, directed to the storage array, or mixed with voice from the
receive path coming from ANA IN and be directed to the same places.
In addition, if the phone is inserted into a "hands-free" car kit, then the signal from the pickup microphone
in the car can be passed through to the same places from the AUX IN pin and the phone's microphone is
switched off. Under this situation, the other party's voice from the phone is played into ANA IN and
passed through to the AUX OUT pin that drives the car kit's loudspeaker.
Depending upon whether one desires recording one side (simplex) or both sides (duplex) of a
conversation, the various paths will also be switched through to the low pass filter (for anti-aliasing) and
into the storage array. Later, the cell phone owner can play back the messages from the array. When
this happens the Array Output MUX is connected to the volume control through the Output MUX to the
Speaker Amplifier.
For applications other than a cell phone, the audio paths can be switched into many different
configurations, providing great flexibility.
