DP7140
Device Operation
START Condition
The DP7140 is a resistor array integrated with a I2C
serial interface logic, an 8ïbit volatile wiper register, and six
8ïbit, nonïvolatile memory data registers. The resistor
array contains 255 separate resistive elements connected in
series. The physical ends of the array are equivalent to the
fixed terminals of a mechanical potentiometer (RH and RL).
The tap positions between and at the ends of the series
resistors are connected to the output wiper terminal (RW) by
CMOS transistor switches. Only one tap point for the
potentiometer is connected to the wiper terminal at a time
and is determined by the value of an 8ïbit Wiper Register
(WR).
The START condition precedes all commands to the
device, and is defined as a HIGH to LOW transition of SDA
when SCL is HIGH. The DP7140 monitors the SDA and
SCL lines and will not respond until this condition is met.
STOP Condition
A LOW to HIGH transition of SDA when SCL is HIGH
determines the STOP condition. All operations must end
with a STOP condition.
Device Addressing
The bus Master begins a transmission by sending a
START condition. The Master then sends the address of the
particular slave device it is requesting. DP7140 has a fixed
7 bit slave address: 0101000. The 8th bit (LSB) is the
Read/Write instruction bit. For a Read the value is “1” and
for Write the value is “0”.
After the Master sends a START condition and the slave
address byte, the DP7140 monitors the bus and responds
with an acknowledge (on the SDA line) when its address
matches the transmitted slave address.

Acknowledge (ACK)
RL
After a successful data transfer, each receiving device is
required to generate an acknowledge. The Acknowledging
device pulls down the SDA line during the ninth clock cycle,
signaling that it received the 8 bits of data.
DP7140 responds with an acknowledge after receiving
a START condition and its slave address. If the device has
been selected along with a write operation, it responds with
an acknowledge after receiving each 8ïbit byte. When the
DP7140 is in a READ mode it transmits 8 bits of data,
releases the SDA line, and monitors the line for an
acknowledge. Once it receives this acknowledge, the
DP7140 will continue to transmit data. If no acknowledge
is sent by the Master, the device terminates data transmission
and waits for a STOP condition.
When power is first applied to DP7140 the wiper is set
to midscale; Wiper Register = 80h. When the power supply
becomes sufficient to read the nonïvolatile memory the
value stored in the Initial Value Register (IVR) is transferred
into the Wiper Register and the wiper moves to this new
position. Five additional 8ïbit nonïvolatile memory data
registers are provided for general purpose data storage. Data
can be read or written to the volatile or the nonïvolatile
memory data registers via the I2C bus.
Serial Bus Protocol
The following defines the features of the 2ïwire bus
protocol:
1. Data transfer may be initiated only when the bus is
not busy.
2. During a data transfer, the data line must remain
stable whenever the clock line is high. Any
changes in the data line while the clock is high
will be interpreted as a START or STOP condition.
The device controlling the transfer is a master, typically a
processor or controller, and the device being controlled is the
slave. The master will always initiate data transfers and
provide the clock for both transmit and receive operations.
Therefore, the DP7140 will be considered a slave device
in all applications.
WRITE Operation
In the Write mode, the Master device sends the START
condition and the slave address information to the Slave
device. In '3·s case the slave address also contains a
Read/Write command (R/W) on the last bit of the 1st byte.
After receiving an acknowledge from the Slave, the Master
device transmits a second byte containing a Memory
Address to select an available register. After a second
acknowledge is received from the Slave, the Master device
sends the data to be written into the selected register. The
DP7140 acknowledges once more and the Master
6
DP7140
READ Operation
generates the STOP condition, at which time if a nonvolatile
data register is being selected, the device begins an internal
programming cycle to nonïvolatile memory. If the STOP
condition is not sent immediately after the last ACK the
internal nonïvolatile programming cycle doesn·t start.
While this internal cycle is in progress, the device will not
respond to any request from the Master device.
Write operations to volatile memory are completed during
the last bit of the data byte before the slave·s acknowledge.
The device will be ready for another command only after a
STOP condition sent by Master.
A Read operation with a designated address consists of a
three byte instruction followed by one or more Data Bytes
(See Figure 3). The master initiates the operation issuing a
START, an Identification byte with the R/W bit set to “0”, an
Address Byte. Then the master sends a second START, and
a second Identification byte with the R/W bit set to “1”. After
each of the three bytes, the DP7140 responds with an ACK.
Then DP7140 transmits the Data Byte. The master then can
continue the read operation with the content of the next
register by sending acknowledge or can terminate the read
operation by issuing a NoACK followed by a STOP
condition after the last bit of a Data Byte.
Acknowledge Polling
The disabling of the inputs can be used to take advantage
of the typical write cycle time. Once the stop condition is
issued to indicate the end of the host·s write operation, the
DP7140 initiates the internal write cycle. ACK polling can
be initiated immediately. This involves issuing the start
condition followed by the slave address. If the DP7140 is
still busy with the write operation, no ACK will be returned.
If the DP7140 has completed the write operation, an
acknowledge will be returned and the host can then proceed
with the next instruction operation.
Table 13. MEMORY MAP
Nonïvolatile
WRITE Protection
The Write Protection feature allows the user to protect
against inadvertent programming of the nonïvolatile data
registers. If the WP pin is tied to LOW, the data registers are
protected and become read only. Similarly, the WP pin going
low after start will interrupt a nonvolatile write to data
registers, while the WP pin going low after an internal write
cycle has started will have no effect on any write operation.
DP7140 will accept slave addresses but the data registers
are protected from programming, which the device indicates
by failing to send an acknowledge after data is received.

A writing to address 1 has no effect. Attempts to do so will return an ACK but no data will be written.
Address 0: IVR/WR Register (I/O)
Address 00h accesses one of two memory registers: the initial value register (IVR) or the wiper register (WR) depending
upon the value of bit 7 in Access Control Register (ACR) which is at address 08h, above.
WR controls the wiper·s position and is a volatile memory while IVR is nonïvolatile and retains its data after the chip has
been powered down. Writes to IVR automatically update the WR while writes to WR leave IVR unaffected.
WR: Wiper Register = Volatile.
IVR: Initial Value Register = Nonïvolatile.
Writing and Reading operations:
1. If Bit 7 from ACR is 0 (nonïvolatile):
g A write operation to address 00h will write the same value in WR and IVR.
g A read operation to address 00h will output the content of IVR.
2. If bit 7 from ACR is 1 (volatile):
g A write operation to address 00h will write in WR only.
g A read operation to address 00h will output the content of WR.
All changes to the wiper·s position are immediate. There is no delay the wiper·s movement when writing to nonïvolatile
memory.
