AT24C04C-MAHM-T Frequently Asked Questions (FAQs)

  • The AT24C04C-MAHM-T has a minimum of 1 million write cycles, but the actual number of write cycles may vary depending on the usage and operating conditions.
  • To ensure data integrity, it is recommended to follow the power-down and power-up sequences outlined in the datasheet, and to use a voltage supervisor or brown-out detector to prevent data corruption during power-down or power-up.
  • The recommended operating voltage range for the AT24C04C-MAHM-T is 1.7V to 5.5V, but it can operate down to 1.6V with reduced performance.
  • The AT24C04C-MAHM-T uses a page-based write architecture, where each page is 8 bytes. To perform a page write, the device must be in page write mode, and the page address must be specified. For block writes, the device must be in block write mode, and the block address must be specified.
  • 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 no writes are allowed. When the WP pin is tied to GND, the device is in normal operation mode.
