Functionality
I2C Serial Clock Line: to clock the data into and out of the I2C interface.
Input pin that supplies the LSB +1 bit for the I2C Slave Address.
I2C Serial Data Line: Data is passed between devices on the bus over
this line.
Input pin that supplies the LSB for the I2C Slave Address.
Digital Ground.
No Connect.
Differential Positive Input for the microphone amplifier.
Analog Ground.
Differential Negative Input for the microphone amplifier.
Differential Positive Analog Output for ANA OUT.
Differential Negative Analog Output for ANA OUT.
AGC/AutoMute Capacitor: Required for the on-chip AGC amplifier during
record and AutoMute function during playback.
Differential Negative Speaker Output: When the speaker outputs are in
use, the AUX OUT output is disabled.
Differential Positive Speaker Output.
Analog Supply Voltage: This pin supplies power to the analog sections
of the device. It should be carefully bypassed to Analog Ground to
insure correct device operation.
Analog Input: one of the analog inputs with selectable gain.
Auxiliary Input: one of the analog inputs with selectable gain.
Auxiliary Output: one the analog outputs of the device. When this
output is used, the SP+ and SP- outputs are disabled.
Row Address Clock; an open drain output. The RAC pin goes LOW
TRACL[1] before the end of each row of memory and returns HIGH at
exactly the end of each row of memory.
Interrupt Output; an open drain output that indicates that a set EOM bit
has been found during Playback or that the chip is in an Overflow (OVF)
condition. This pin remains LOW until a Read Status command is
executed.
This pin allows the internal clock of the device to be driven externally for
enhanced timing precision. This pin is grounded for most applications.
Digital Supply Voltage. These pins supply power to the digital sections
of the device. They must be carefully bypassed to Digital Ground to
insure correct device operation.

ISD5100 – SERIES
7.3.2. I2C Control Registers
The ISD5100 Series are controlled by loading commands to, or, reading from, the internal command,
configuration and address registers. The Command byte sent is used to start and stop recording, write
or read digital data and perform other functions necessary for the operation of the device.
Command Byte
Control of the ISD5100 Series are implemented through an 8-bit command byte, sent after the 7-bit
device address and the 1-bit Read/Write selection bit. The 8 bits are:
Global power up bit
DAB bit: determines whether device is performing an analog or digital function
3 function bits: these determine which function the device is to perform in conjunction
with the DAB bit.
3 register address bits: these determine if and when data is to be loaded to a register

Function Bits
The command byte function bits are
detailed in the table to the right. C6, the
DAB bit, determines whether the
device is performing an analog or
digital function. The other bits are
decoded to produce the individual
commands. Not all decode
combinations are currently used, and
are reserved for future use. Out of 16
possible codes, the ISD5100 Series
uses 7 for normal operation. The other
9 are undefined
