AT24C01B-TH-B Frequently Asked Questions (FAQs)

  • The AT24C01B has an endurance of 1 million write cycles, with a minimum of 100,000 cycles guaranteed.
  • The AT24C01B uses a page write buffer to handle writes. The buffer is 16 bytes, and the device will automatically write the buffer to memory when it is full or when a stop command is received.
  • The WP (Write Protect) pin is used to prevent writes to the entire memory array. When the WP pin is tied low, the entire memory array is write-protected.
  • Yes, the AT24C01B supports multi-master environments. It has a built-in arbitration mechanism that allows multiple masters to access the device without the need for external arbitration.
  • The maximum clock frequency for the AT24C01B is 400 kHz.
