X9241 General Description
The X9241 integrates four nonvolatile E2POT digitally controlled potentiometers on a monolithic CMOS microcircuit.
The X9241 contains four resistor arrays, each composed of 63 resistive elements. Between each element and at either end are tap points accessible to the wiper elements. The position of the wiper element on the array is controlled by the user through the two-wire serial bus interface.
Each resistor array has associated with it a wiper counter register and four 8-bit data registers that can be directly written and read by the user. The contents of the wiper counter register control the position of the wiper on the resistor array.
The data register may be read or written by the user. The contents of the data registers can be transferred to the wiper counter register to position the wiper. The current wiper position can be transferred to any one of its associated data registers.
The arrays may be cascaded to form resistive elements with 127, 190 or 253 taps.

X9241A General Description
The X9241A integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated microcircuit. The digitally controlled potentiometer is implemented using 63 resistive elements in a series array. Between each element are tap points connected to the wiper terminal through switches. The position of the wiper on the array is controlled by the user through the 2-wire bus interface. Each potentiometer has associated with it a volatile Wiper Counter Register (WCR) and 4 nonvolatile Data Registers (DR0:DR3) that can be directly written to and read by the user. The contents of the WCR controls the position of the wiper on the resistor array through the switches. Power up recalls the contents of DR0 to the WCR. The XDCP can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing.
