DESCRIPTION
The CAT5411 is two Digitally Programmable Potentiometers (DPPsTM) 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 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 can be used as a potentiometer or as a two terminal, variable resistor. It is intended for circuit level or system level adjustments in a wide variety of applications.

SI: Serial Input SI is the serial data input pin. This pin is used to input all opcodes, byte addresses and data to be written to the CAT5411. Input data is latched on the rising edge of the serial clock. 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. RH, RL: Resistor End Points The RH and RL pins are equivalent to the terminal connections on a mechanical potentiometer. Wiper 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: Write Protect WP 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
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. 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.
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
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). 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.
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. Data Register Selection Data Register Selected DR0 DR1 DR2 DR3 R1 0 0 1 1 R0 0 1 0 1

CAT5411
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. 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. Data Registers (DR) 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 Table 3.

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. 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.

CAT5411
when set to "1" signifies a write cycle is in progress. 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. 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. Figure 7. Two-Byte Instruction Sequence
SI 0 1 0 1 0 0
-- Global XFR Data Register to Wiper Control Register This transfers the contents of all specified Data Registers to the associated Wiper Control Registers. -- 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. See Instructions format for more detail.
