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 X9241 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 X9241 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.
