is used. All operations however must begin with the
Slave Address Byte being issued on the SDA pin. The

is to be performed.
It should be noted that in order to perform a write oper-

ation to either a DCP or the EEPROM array, the Write

BL0: Block Lock protection bits - (Nonvolatile)” on
page 18.)
Slave Address Byte
Following a START condition, the master must output
a Slave Address Byte (Refer to Figure 4). This byte
consists of three parts:
—The Device Type Identifier which consists of the most
significant four bits of the Slave Address (SA7 - SA4).
The Device Type Identifier must always be set to 1010

Address bits. Setting these bits to 000 internally
selects the EEPROM array, while setting these bits to
111 selects the DCP structures in the X4023x. The CR
Register may be selected using the Internal Device
Address 010.
—The Least Significant Bit of the Slave Address (SA0)
Byte is the R/W bit. This bit defines the operation to be
performed on the device being addressed (as defined
in the bits SA3 - SA1). When the R/W bit is “1”, then a
READ operation is selected. A “0” selects a WRITE
To perform acknowledge polling, the master issues a
START condition followed by a Slave Address Byte.
The Slave Address issued must contain a valid Inter-
nal Device Address. The LSB of the Slave Address
(R/W) can be set to either 1 or 0 in this case. If the
device is still busy with the high voltage cycle then no
ACKNOWLEDGE will be returned. If the device has
completed the write operation, an ACKNOWLEDGE
will be returned and the host can then proceed with a
read or write operation. (Refer to Figure 5)

DIGITALLY CONTROLLED POTENTIOMETERS
Nonvolatile Write Acknowledge Polling
After a nonvolatile write command sequence (for either
the EEPROM array, the Non Volatile Memory of a DCP
(NVM), or the CR Register) has been correctly issued
(including the final STOP condition), the X4023x ini-
tiates an internal high voltage write cycle. This cycle
typically requires 5 ms. During this time, no further
Read or Write commands can be issued to the device.
Write Acknowledge Polling is used to determine when
this high voltage write cycle has been completed.

DCP Functionality
The X4023x includes one or two independent resistor
arrays. For the 64, 100 or 256 tap XDCPs, these
arrays respectively contain 63, 99 discrete resistive
segments that are connected in series. (the 256 tap
resistor achieves an equivalent end to end resistance.)
The physical ends of each array are equivalent to the
fixed terminals of a mechanical potentiometer. At one
end of the resistor array the terminal connects to the
R Hx pin (x = 0,1,2).The other end of the resistor array
is connected to V SS inside the package.
