The X9315TP is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics America. It integrates a resistor array, wiper switches, control logic, and non-volatile memory in a single chip. This allows for precise adjustment of resistance values using digital signals, and the programmed resistance can be stored even when power is removed.

Technical Specifications
The X9315TP is characterized by its end-to-end resistance, number of taps, interface type, and operating voltage range. The end-to-end resistance specifies the total resistance value between the two end terminals. The number of taps indicates the number of discrete resistance steps. The interface type is typically a serial interface, such as SPI or I2C. The operating voltage range specifies the acceptable supply voltage range for the device. The device is generally available in small surface-mount packages, such as SOIC or TSSOP. The operating temperature range is usually between -40°C to +85°C.
