24AA256UID-I/ST Frequently Asked Questions (FAQs)

  • The 24AA256UID-I/ST has a minimum of 1 million write cycles, but the actual number of write cycles may vary depending on the usage and operating conditions.
  • The 24AA256UID-I/ST uses a page write buffer to handle page writes. The device can write up to 64 bytes of data in a single page write operation.
  • The WP (Write Protect) pin is used to prevent accidental writes to the device. When the WP pin is tied to VCC, the device is in write-protect mode, and any attempt to write to the device will be ignored.
  • Yes, the 24AA256UID-I/ST can be used in a multi-master bus configuration. The device supports a multi-master I2C bus interface, allowing multiple masters to access the device simultaneously.
  • The maximum clock frequency for the 24AA256UID-I/ST is 400 kHz. However, the device can also operate at lower clock frequencies, such as 100 kHz or 200 kHz, depending on the application requirements.
