Renesas Electronics X9400
The X9400 integrates four digitally controlled potentiometers (XDCPs) on a monolithic CMOS integrated circuit. The digitally controlled potentiometer is implemented using 63 resistive elements in a series array. The position of the wiper on the array is controlled by the user through the SPI serial bus interface.| Part No. | X9400 |

DESCRIPTION
Between each element are tap points connected to the wiper terminal through switches. Each potentiometer has associated with it a volatile Wiper Counter Register (WCR) and four nonvolatile Data Registers (DR0-3) 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.
