25LC040AX-I/ST Frequently Asked Questions (FAQ)

  • The 25LC040AX-I/ST has a minimum of 1,000,000 write cycles, but the actual number of write cycles may vary depending on the usage and operating conditions.

  • The 25LC040AX-I/ST 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.

  • The WP (Write Protect) pin is used to prevent writes to the status register and the memory array. When the WP pin is tied to VCC, the device is in write-protect mode, and when it is tied to GND, the device is in normal operation mode.

  • Yes, the 25LC040AX-I/ST can be used in a multi-master environment. The device has a built-in arbitration mechanism that allows multiple masters to access the device without conflicts.

  • The maximum clock frequency for the 25LC040AX-I/ST is 10 MHz.
