X9250US24Z-2.7 - Renesas Electronics

Description: The X9250 integrates 4 digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. The digitally controlled potentiometer is implemented using 255 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 SPI bus interface. Each potentiometer has associated with it a volatile Wiper Counter Register (WCR) and 4 nonvolatile Data Registers (DR0:D

X9250US24Z-2.7 Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the X9250US24Z-2.7 is 2.7V to 5.5V.
  • To ensure proper initialization, the X9250US24Z-2.7 requires a power-on reset (POR) circuit to hold the chip in reset until the power supply has stabilized. A 10kΩ pull-up resistor on the SCL line and a 10kΩ pull-down resistor on the SDA line are also recommended.
  • The X9250US24Z-2.7 supports clock frequencies up to 400 kHz in standard mode and up to 1 MHz in fast mode.
  • To handle bus contention and arbitration, implement a bus arbitration scheme using the X9250US24Z-2.7's built-in arbitration logic. This involves monitoring the SDA line for bus contention and using the clock stretching feature to resolve conflicts.
  • The internal EEPROM is used to store configuration data, such as the device's I2C address and other settings. To access the EEPROM, use the X9250US24Z-2.7's I2C interface to read and write data to the designated EEPROM addresses.
