24LC32AT-E/OT Frequently Asked Questions (FAQs)

  • The 24LC32AT-E/OT has a maximum of 1 million write cycles, with a minimum of 100,000 write cycles guaranteed.
  • The 24LC32AT-E/OT uses a page write buffer to handle page writes. The buffer is 32 bytes, and the device can perform a page write in 5ms (typical) or 10ms (maximum).
  • The WP (Write Protect) pin is used to prevent writes to the entire memory array or specific blocks of memory. When WP is low, the entire memory array is write-protected. When WP is high, the device operates normally.
  • The 24LC32AT-E/OT has a built-in power-on reset circuit that resets the device to a known state when power is applied. The device also has a brown-out detector that resets the device if the supply voltage falls below a certain threshold.
  • The maximum clock frequency for the 24LC32AT-E/OT is 400 kHz.
