CAT24C256WI-G Frequently Asked Questions (FAQs)

  • The CAT24C256WI-G 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 CAT24C256WI-G 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 a write-protected state, and any attempt to write to the device will be ignored.
  • Yes, the CAT24C256WI-G 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 CAT24C256WI-G is 400 kHz. However, the device can operate at frequencies up to 1 MHz in fast mode.
