25LC640-I/SNG Frequently Asked Questions (FAQ)

  • The 25LC640-I/SNG has a maximum of 1,000,000 write cycles, with a minimum of 100,000 write cycles guaranteed.

  • The 25LC640-I/SNG 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 status register. When the WP pin is tied to VCC, the status register is write-protected. When the WP pin is tied to GND, the status register can be written to.

  • The 25LC640-I/SNG has a power-on reset (POR) circuit that resets the device during power-up. During power-down, the device enters a low-power standby mode to conserve power.

  • The maximum clock frequency for the 25LC640-I/SNG is 10 MHz.
