DESCRIPTION
wiper control register or any of the non-volatile data
registers is via a SPI serial bus. On power-up, the
contents of the first data register (DR0) for each of the
two potentiometers is automatically loaded into its
respective wiper control register.
The CAT5411 is two Digitally Programmable
Potentiometers (DPPs™) integrated with control logic
and 16 bytes of NVRAM memory. Each DPP consists of
a series of 63 resistive elements connected between two
externally accessible end points. The tap points between
each resistive element are connected to the wiper outputs
with CMOS switches. A separate 6-bit control register
(WCR) independently controls the wiper tap switches for
each DPP. Associated with each wiper control register
are four 6-bit non-volatile memory data registers (DR)
used for storing up to four wiper settings. Writing to the

SCK
SO:
Serial Output
SO is the serial data output pin. This pin is used to
transfer data out of the CAT5411. During a read
cycle, data is shifted out on the falling edge of the
serial clock.
SCK:
Serial Clock
SCK is the serial clock pin. This pin is used to
synchronize the communication between the
microcontroller and the CAT5411. Opcodes, byte
addresses or data present on the SI pin are latched
on the rising edge of the SCK. Data on the SO pin is
updated on the falling edge of the SCK.
A0, A1: Device Address Inputs
These inputs set the device address when addressing multiple devices. A total of four devices can be
addressed on a single bus. A match in the slave
address must be made with the address input in
order to initiate communication with the CAT5411.

RW:
The RW pins are equivalent to the wiper terminal of a
mechanical potentiometer.
CS
CS:
Chip Select
CS is the Chip select pin. CS low enables the
CAT5411 and CS high disables the CAT5411. CS high
takes the SO output pin to high impedance and forces the devices into a Standby mode (unless an internal write operation is
underway). The CAT5411 draws ZERO current in the Standby mode. A high to low transition on CS is required prior to any
sequence being initiated. A low to high transition on CS after a valid write sequence is what initiates an internal write cycle.
WP
WP:
Write Protect
WP is the Write Protect pin. The Write Protect pin will allow normal read/write operations when held high. When WP is tied low, all
non-volatile write operations to the Data registers are inhibited (change of wiper control register is allowed). WP going low while
CS is still low will interrupt a write to the registers. If the internal write cycle has already been initiated, WP going low will have no
effect on any write operation.
HOLD
HOLD: Hold
The HOLD pin is used to pause transmission to the CAT5411 while in the middle of a serial sequence without having to retransmit entire sequence at a later time. To pause, HOLD must be brought low while SCK is low. The SO pin is in a high impedance state during the time the part is paused, and transitions on the SI pins will be ignored. To resume communication, HOLD is
brought high, while SCK is low. (HOLD should be held high any time this function is not being used.) HOLD may be tied high
directly to VCC or tied to VCC through a resistor.

CAT5411
SERIAL BUS PROTOCOL
After the device is selected with CS going low the first
byte will be received. The part is accessed via the SI pin,
with data being clocked in on the rising edge of SCK. The
first byte contains one of the six op-codes that define the
operation to be performed.
The CAT5041 supports the SPI bus data transmission
protocol. The synchronous Serial Peripheral Interface
(SPI) helps the CAT5411 to interface directly with many
of today's popular microcontrollers. The CAT5041
contains an 8-bit instruction register .The instruction set
and the operation codes are detailed in the instruction
set table 3.
DEVICE OPERATION
The CAT5411 is two resistor arrays integrated with SPI
serial interface logic, four 6-bit wiper control registers
and eight 6-bit, non-volatile memory data registers.
Each resistor array contains 63 separate resistive
elements connected in series. The physical ends of
each array are equivalent to the fixed terminals of a
mechanical potentiometer (RH and RL). RH and RL are
symmetrical and may be interchanged. The tap positions
between and at the ends of the series resistors are
connected to the output wiper terminals (RW) by a
CMOS transistor switch. Only one tap point for each
potentiometer is connected to its wiper terminal at a time
and is determined by the value of the wiper control
register. Data can be read or written to the wiper control
registers or the non-volatile memory data registers via
the SPI bus. Additional instructions allows data to be
transferred between the wiper control registers and
each respective potentiometer's non-volatile data
registers. Also, the device can be instructed to operate
in an "increment/decrement" mode.

CAT5411
INSTRUCTION AND REGISTER
DESCRIPTION
INSTRUCTION BYTE
The next byte sent to the CAT5411 contains the instruction
and register pointer information. The four most significant
bits used provide the instruction opcode I [3:0]. The R1
and R0 bits point to one of the four data registers of each
associated potentiometer. The least two significant bits
point to one of two Wiper Control Registers. The format
is shown in Table 2.
DEVICE TYPE / ADDRESS BYTE
The first byte sent to the CAT5411 from the master/
processor is called the Device Address Byte. The most
significant four bits of the Device Type address are a
device type identifier. These bits for the CAT5411 are
fixed at 0101[B] (refer to Table 1).
Data Register Selection
Data Register Selected
The two least significant bits in the slave address byte,
A1 - A0, are the internal slave address and must match
the physical device address which is defined by the state
of the A1 - A0 input pins for the CAT5411 to successfully
continue the command sequence. Only the device which
slave address matches the incoming device address
sent by the master executes the instruction. The A1 - A0
inputs can be actively driven by CMOS input signals or
tied to VCC or VSS. The remaining two bits in the device
address byte must be set to 0.

CAT5411
four Data Registers and the associated Wiper Control
Register. Any data changes in one of the Data Registers
is a non-volatile operation and will take a maximum of
5ms.
WIPER CONTROL AND DATA REGISTERS
Wiper Control Register (WCR)
The CAT5411 contains two 6-bit Wiper Control
Registers, one for each potentiometer. The Wiper
Control Register output is decoded to select one of 64
switches along its resistor array. The contents of the
WCR can be altered in four ways: it may be written by
the host via Write Wiper Control Register instruction;
it may be written by transferring the contents of one of
four associated Data Registers via the XFR Data
Register instruction, it can be modified one step at a
time by the Increment/decrement instruction (see
Instruction section for more details). Finally, it is
loaded with the content of its data register zero (DR0)
upon power-up.
Write in Process
The contents of the Data Registers are saved to
nonvolatile memory when the CS input goes HIGH after
a write sequence is received. The status of the internal
write cycle can be monitored by issuing a Read Status
command to read the Write in Process (WIP) bit.
INSTRUCTIONS
Five of the ten instructions are three bytes in length.
These instructions are:
— Read Wiper Control Register - read the current
wiper position of the selected potentiometer in the WCR
The Wiper Control Register is a volatile register that
loses its contents when the CAT5411 is powered-down.
Although the register is automatically loaded with the
value in DR0 upon power-up, this may be different from
the value present at power-down.
— Write Wiper Control Register - change current
wiper position in the WCR of the selected potentiometer
— Read Data Register - read the contents of the
selected Data Register
Data Registers (DR)
— Write Data Register - write a new value to the
selected Data Register
Each potentiometer has four 6-bit non-volatile Data
Registers. These can be read or written directly by the
host. Data can also be transferred between any of the
— Read Status - Read the status of the WIP bit which

when set to "1" signifies a write cycle is in progress.
— Global XFR Data Register to Wiper
Control Register
This transfers the contents of all specified Data
Registers to the associated Wiper Control
Registers.
The basic sequence of the three byte instructions is
illustrated in Figure 8. These three-byte instructions
exchange data between the WCR and one of the Data
Registers. The WCR controls the position of the wiper.
The response of the wiper to this action will be delayed
by tWRL. A transfer from the WCR (current wiper position),
to a Data Register is a write to non-volatile memory and
takes a minimum of tWR to complete. The transfer can
occur between one of the potentiometers and one of its
associated registers; or the transfer can occur between
both potentiometers and one associated register.
— Global XFR Wiper Counter Register to
Data Register
This transfers the contents of all Wiper Control
Registers to the specified associated Data
Registers.
INCREMENT/DECREMENT COMMAND
The final command is Increment/Decrement (Figure 5
and 9). The Increment/Decrement command is different
from the other commands. Once the command is issued
the master can clock the selected wiper up and/or down
in one segment steps; thereby providing a fine tuning
capability to the host. For each SCK clock pulse (tHIGH)
while SI is HIGH, the selected wiper will move one
resistor segment towards the RH terminal. Similarly, for
each SCK clock pulse while SI is LOW, the selected
wiper will move one resistor segment towards the RL
terminal.
Four instructions require a two-byte sequence to
complete, as illustrated in Figure 7. These instructions
transfer data between the host/processor and the
CAT5411; either between the host and one of the data
registers or directly between the host and the Wiper
Control Register. These instructions are:
— XFR Data Register to Wiper Control Register
This transfers the contents of one specified Data
Register to the associated Wiper Control Register.
— XFR Wiper Control Register to Data Register
This transfers the contents of the specified Wiper
Control Register to the specified associated
Data Register.
