AT24CSW040-UUM0B-T Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the I2C interface is 400 kHz.
  • Page writes are limited to 32 bytes, and block writes are limited to 128 bytes. The device will automatically wrap around to the beginning of the page or block if the write exceeds the limit.
  • The WP (Write Protect) pin is used to prevent writes to the entire device or a specific section of the device. When WP is low, the entire device is write-protected. When WP is high, the device can be written to.
  • The device must be powered up and down slowly (dv/dt < 10 mV/μs) to prevent latch-up. The device is not accessible during power-up and power-down sequences.
  • The device has an endurance of 1 million write cycles, with a minimum retention period of 100 years.
