... I C Bus, 256 Taps, 5 Bytes General Purpose Memory, Low Noise, Low Power The ISL95811 integrates a digitally controlled potentiometer (XDCP) and non-volatile memory on a monolithic CMOS integrated circuit. The digitally controlled potentiometer is implemented with a combination of resistor elements and CMOS switches. The position of the wiper is controlled by the user through the I bus interface ...

... Pin Description www.DataSheet4U.com Potentiometers Pins RH AND RL The high (RH) and low (RL) terminals of the ISL95811 are equivalent to the fixed terminals of a mechanical potentiometer. RH and RL are referenced to the relative position of the wiper and not the voltage potential on the terminals. With WR set to 255 decimal, the wiper will be closest to RH, and with the WR set to 0, the wiper is closest to RL ...

... RW and RL increases monotonically, while the resistance between RH and RW decreases monotonically. While the ISL95811 is being powered up, the WR is reset to 80h (128 decimal), which locates RW roughly at the center between RL and RH. After the power supply voltage becomes large enough for reliable non-volatile memory reading, the WR will be reloaded with the value stored in a www ...

... Protocol Conventions Data states on the SDA line can change only during SCL LOW periods. SDA state changes during SCL HIGH are reserved for indicating START and STOP conditions (see Figure 17). On power-up of the ISL95811, the SDA pin is in the input mode. 2 All I ...

... Identification Byte, a valid Address Byte, a Data Byte, and a STOP condition. After each of the three bytes, the ISL95811 responds with an ACK. At this time, if the Data Byte written only to volatile registers, then the device enters its standby state. If the Data Byte written also to non-volatile memory, the ISL95811 begins its internal write www ...
