X9250UV24IZ-2.7T2 - 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

X9250UV24IZ-2.7T2 Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the X9250UV24IZ-2.7T2 is 20 MHz.
  • To avoid data corruption, it's essential to follow the page write protocol outlined in the datasheet. This includes sending a Write Enable (WREN) command, followed by the page address and data, and then a Write Disable (WRDI) command to prevent accidental writes.
  • The Hold (HOLD) pin is used to pause the serial communication between the microcontroller and the X9250UV24IZ-2.7T2. When the HOLD pin is driven low, the serial communication is suspended, and the device enters a low-power state.
  • The X9250UV24IZ-2.7T2 provides a Write-In-Progress (WIP) bit in the Status Register. By polling the WIP bit, you can determine if a write operation is in progress or has completed.
  • The recommended power-up sequence is to apply VCC first, followed by the CS (Chip Select) pin going low, and then the SCK (Serial Clock) pin can be driven. This ensures proper device initialization and prevents unintended writes.
