LARGE SIGNAL SETTLING TIME FN8094.1 February 8, 2006 ISL90841 Principles of Operation The ISL90841 is an integrated circuit incorporating four DCPs with their associated registers, and an I2C serial interface providing direct communication between a host and the potentiometers. DCP Description All I2C interface operations must begin with a START condition, which is a HIGH to LOW transition of SDA while SCL is HIGH. The ISL90841 continuously monitors the SDA and SCL lines for the START condition and does not respond to any command until this condition is met (See Figure 15). A START condition is ignored during the powerup of the device. Each DCP is implemented with a combination of resistor elements and CMOS switches. The physical ends of each DCP are equivalent to the fixed terminals of a mechanical potentiometer (RH and GND). The RW pin of each DCP is connected to intermediate nodes, and is equivalent to the wiper terminal of a mechanical potentiometer. The position of the wiper terminal within the DCP is controlled by an 8-bit volatile Wiper Register (WR). Each DCP has its own WR. When the WR of a DCP contains all zeroes (WR<7:0>: 00h), its wiper terminal (RW) is closest to its “Low” terminal (GND). When the WR of a DCP contains all ones (WR<7:0>: FFh), its wiper terminal (RW) is closest to its “High” terminal (RH). As the value of the WR increases from all zeroes (00h) to all ones (255 decimal), the wiper moves monotonically from the position closest to GND to the closest to RH. At the same time, the resistance between RW and GND increases monotonically, while the resistance between RH and RW decreases monotonically. All I2C interface operations must be terminated by a STOP condition, which is a LOW to HIGH transition of SDA while SCL is HIGH (See Figure 15). A STOP condition at the end of a read operation, or at the end of a write operation places the device in its standby mode. While the ISL90841 is being powered up, all four WRs are reset to 80h (128 decimal), which locates RW roughly at the center between GND and RH. A valid Identification Byte contains 01010 as the five MSBs, and the following two bits matching the logic values present at pins A1 and A0. The LSB is the Read/Write bit. Its value is “1” for a Read operation, and “0” for a Write operation (See Table 1). The WRs can be read or written directly using the I2C serial interface as described in the following sections. The I2C interface Address Byte has to be set to 00h, 01h, 02h, and 03h to access the WR of DCP0, DCP1, DCP2, and DCP3 respectively I2C Serial Interface An ACK, Acknowledge, is a software convention used to indicate a successful data transfer. The transmitting device, either master or slave, releases the SDA bus after transmitting eight bits. During the ninth clock cycle, the receiver pulls the SDA line LOW to acknowledge the reception of the eight bits of data (See Figure 16). The ISL90841 responds with an ACK after recognition of a START condition followed by a valid Identification Byte, and once again after successful receipt of an Address Byte. The ISL90841 also responds with an ACK after receiving a Data Byte of a write operation. The master must respond with an ACK after receiving a Data Byte of a read operation TABLE 1. IDENTIFICATION BYTE FORMAT Logic values at pins A1 and A0 respectively 0 The ISL90841 supports a bidirectional bus oriented protocol. The protocol defines any device that sends data onto the bus as a transmitter and the receiving device as the receiver. The device controlling the transfer is a master and the device being controlled is the slave. The master always initiates data transfers and provides the clock for both transmit and receive operations. Therefore, the ISL90841 operates as a slave device in all applications. (MSB) 1 0 1 0 A1 A0 R/W (LSB) All communication over the I2C interface is conducted by sending the MSB of each byte of data first. Protocol Conventions Data states on the SDA line must change only during SCL LOW periods. SDA state changes during SCL HIGH are reserved for indicating START and STOP conditions (See Figure 15). On power-up of the ISL90841 the SDA pin is in the input mode. 9 FN8094.1 February 8, 2006 ISL90841 SCL SDA START DATA STABLE DATA CHANGE DATA STABLE STOP FIGURE 15.

READ SEQUENCE 10 FN8094.1 February 8, 2006 ISL90841 Write Operation A Write operation requires a START condition, followed by a valid Identification Byte, a valid Address Byte, a Data Byte, and a STOP condition. After each of the three bytes, the ISL90841 responds with an ACK. At this time, the device enters its standby state (See Figure 17). Read Operation A Read operation consist of a three byte instruction followed by one or more Data Bytes (See Figure 18). The master initiates the operation issuing the following sequence: a START, the Identification byte with the R/W bit set to “0”, an Address Byte, a second START, and a second Identification byte with the R/W bit set to “1”. After each of the three bytes, the ISL90841 responds with an ACK. Then the ISL90841 transmits Data Bytes as long as the master responds with an ACK during the SCL cycle following the eighth bit of each byte. The master terminates the read operation (issuing a STOP condition) following the last bit of the last Data Byte (See Figure 18). The Data Bytes are from the registers indicated by an internal pointer. This pointer initial value is determined by the Address Byte in the Read operation instruction, and increments by one during transmission of each Data Byte. After reaching the memory location 03h the pointer “rolls over” to 00h, and the device continues to output data for each ACK received. 11 FN8094.1 February 8, 2006 ISL90841 Packaging Information 14-Lead Plastic, TSSOP, Package Code V14 .025 (.65) BSC .169 (4.3) .252 (6.4) BSC .177 (4.5) .193 (4.9) .200 (5.1) .041 (1.05) .0075 (.19) .0118 (.30) .002 (.05) .006 (.15) .010 (.25) Gage Plane 0° - 8° Seating Plane .019 (.50) .029 (.75) Detail A (20X) .031 (.80) .041 (1.05) See Detail “A” NOTE: ALL DIMENSIONS IN INCHES (IN PARENTHESES IN MILLIMETERS) All Intersil U.S. products are manufactured, assembled and tested utilizing ISO9000 quality systems.
