CAT24C256WI-GT3 datasheet by Catalyst Semiconductor

CAT24C256WI-GT3 Frequently Asked Questions (FAQs)

• What is the maximum number of write cycles for the CAT24C256WI-GT3?
  The CAT24C256WI-GT3 has an endurance of 1 million write cycles, which means it can withstand up to 1 million write operations before the device may start to degrade.
• How does the CAT24C256WI-GT3 handle page writes?
  The CAT24C256WI-GT3 uses a page write buffer to handle page writes. The device can write up to 128 bytes of data in a single page write operation, and the page write buffer is automatically enabled when a write operation is initiated.
• What is the purpose of the WP pin on the CAT24C256WI-GT3?
  The WP (Write Protect) pin is used to prevent accidental writes to the device. When the WP pin is tied to VCC, the entire memory array is write-protected. When the WP pin is tied to GND, the device can be written to normally.
• How does the CAT24C256WI-GT3 handle power-up and power-down?
  The CAT24C256WI-GT3 has a built-in power-on reset (POR) circuit that ensures the device is in a known state during power-up. During power-down, the device automatically enters a low-power standby mode to conserve power.
• Is the CAT24C256WI-GT3 compatible with 5V systems?
  Yes, the CAT24C256WI-GT3 is compatible with 5V systems. The device operates from a supply voltage range of 2.5V to 5.5V, making it suitable for use in both 3.3V and 5V systems.
