X9251UV24IZ-2.7 - Renesas Electronics

Description: The X9251 integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are implemented with a combination of resistor elements and CMOS switches. The position of the wipers are controlled by the user through the SPI bus interface. Each potentiometer has associated with it a volatile Wiper Counter Register (WCR) and four nonvolatile Data Registers that can be directly written to and read by the user. The content of the WCR control

X9251UV24IZ-2.7 Frequently Asked Questions (FAQs)

  • The X9251UV24IZ-2.7 has a minimum of 1,000,000 write cycles, but the actual number of write cycles may vary depending on the application and usage.
  • The X9251UV24IZ-2.7 uses a page-based write architecture. Each page is 128 bytes, and block writes are not supported. You should ensure that your write operations are aligned to the page boundaries to avoid unnecessary page erases.
  • The X9251UV24IZ-2.7 supports clock frequencies up to 400 kHz. However, it's recommended to use a clock frequency of 100 kHz or lower to ensure reliable operation and minimize power consumption.
  • The X9251UV24IZ-2.7 has a built-in power-on reset circuit. During power-up, the device will automatically reset and enter a low-power state. When powering down, ensure that the I2C bus is idle and the device is in a low-power state to prevent data corruption.
  • In the event of a bus conflict or arbitration, the X9251UV24IZ-2.7 will relinquish the bus and enter a high-impedance state. The device will re-attempt to access the bus when the conflict is resolved.
