Description
14
MP7
D_IO
Multipurpose GPIO or Serial Output Port Data 1 (SDATA_OUT1). See the Multipurpose Pins
section for more details.
15
MP6
D_IO
Multipurpose GPIO, Serial Output Port Data 0, or TDM Data Output (SDATA_OUT0). See the
Multipurpose Pins section for more details.
16
MP10
D_IO
Multipurpose GPIO or Serial Output Port LRCLK (OUTPUT_LRCLK). See the Multipurpose
Pins section for more details.
17
VDRIVE
A_OUT
Drive for 1.8 V Regulator. The base of the voltage regulator external PNP transistor is
driven from VDRIVE. See the Voltage Regulator section for details.
18
IOVDD
PWR
Supply for Input and Output Pins. The voltage on this pin sets the highest input voltage
that should be seen on the digital input pins. This pin is also the supply for the digital
output signals on the control port and MP pins. Always set IOVDD to 3.3 V. The current
draw of this pin is variable because it is dependent on the loads of the digital outputs.
19
MP11
D_IO
Multipurpose GPIO or Serial Output Port BCLK (OUTPUT_BCLK). See the Multipurpose Pins
section for more details.
20
ADDR1/CDATA/WB
D_IN
I2C Address 1/SPI Data Input/EEPROM Write Back Trigger. This is a multifunction pin as
follows:
ADDR1: In combination with ADDR0, this sets the I2C address of the IC so that four
CDATA: See the SPI Port section for details.
WB: A rising (default) or falling (if set in the EEPROM messages) edge on this pin triggers a
writeback of the interface registers to the external EEPROM. This function can be used to
save parameter data on power-down. See the Self-Boot section for details.
21
CLATCH/WP
D_IO
SPI Latch Signal/ Self-Boot EEPROM Write Protect. This is a multifunction pin as follows:
CLATCH: must go low at the beginning of an SPI transaction and high at the end of a
transaction. Each SPI transaction can take a different number of cycles on the CCLK pin to
complete, depending on the address and read/write bit that are sent at the beginning of
the SPI transaction. See the SPI Port section for details.
WP: an open-collector output pin when in self-boot mode. The ADAU1702 pulls this low to
enable writes to an external EEPROM. This pin should be pulled high to 3.3 V. See the Self-
Boot section for details.
22
SDA/COUT
D_IO
I2C Data/ SPI Data Output. This is a multifunction pin, as follows:
SDA: this is for I2C data and is a bidirectional open-collector pin. The line connected to this
pin should have a 2.2 kΩ pull-up resistor. See the I2C Port section for details.
COUT: this SPI data output is used for reading back registers and memory locations. It is
three-stated when an SPI read is not active. See the SPI Port section for details.
23
SCL/CCLK
D_IO
I2C Clock/SPI Clock. This is a multifunction pin, as follows:
SCL: this pin function is for the I2C clock and is always an open-collector input when in I2C
control mode. In self-boot mode, this pin is an open-collector output (I2C master). The line
connected to this pin should have a 2.2 kΩ pull-up resistor. See the I2C Port section for
details.
CCLK: this pin function is for the SPI Clock and it either runs continuously or is gated off
between SPI transactions. See the SPI Port section for details.
26
MP9
D_IO/A_IO
Multipurpose GPIO, Serial Output Port Data 3 (SDATA_OUT3), or Auxiliary ADC Input 0. See
the Multipurpose Pins section for more details.
27
MP8
D_IO/A_IO
Multipurpose GPIO, Serial Output Port Data 2 (SDATA_OUT2), or Auxiliary ADC Input 3. See
the Multipurpose Pins section for more details.
28
MP3
D_IO/A_IO
Multipurpose GPIO, Serial Input Port Data 3 (SDATA_IN3), or Auxiliary ADC Input 2. See the
Multipurpose Pins section for more details.
29
MP2
D_IO/A_IO
Multipurpose GPIO, Serial Input Port Data 2 (SDATA_IN2), or Auxiliary ADC Input 1. See the
Multipurpose Pins section for more details.
30
RSVD
N/A
Reserved. Tie to ground, either directly or through a pull-down resistor.
31
OSCO
D_OUT
Crystal Oscillator Circuit Output. Connect a 100 Ω damping resistor between this pin and
the crystal. Do not use this output to directly drive a clock to another IC. If the crystal
oscillator is not used, this pin can be left disconnected. See the Using the Oscillator
section for details.
32
MCLKI
D_IN
Master Clock Input. MCLKI can either be connected to a 3.3 V clock signal or be the input
from the crystal oscillator circuit. See the Setting Master Clock/PLL Mode section for details.
