25AA640AX-I/ST Frequently Asked Questions (FAQ)

  • The 25AA640AX-I/ST has a maximum of 1,000,000 write cycles, with a minimum of 100,000 write cycles guaranteed.

  • The 25AA640AX-I/ST uses a page write buffer to handle page writes. The buffer is 128 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 device or a specific block of memory. When the WP pin is tied to VCC, the entire device is write-protected. When the WP pin is tied to a specific block's WP pin, only that block is write-protected.

  • The 25AA640AX-I/ST has a power-on reset circuit that ensures the device is in a known state after power-up. During power-down, the device automatically goes into a low-power standby mode to conserve power.

  • The 25AA640AX-I/ST operates from 1.8V to 5.5V, making it suitable for a wide range of applications.
