25LC640A-E/SN Frequently Asked Questions (FAQs)

  • The 25LC640A-E/SN has a maximum of 1 million write cycles, with a minimum of 100,000 write cycles guaranteed.
  • The 25LC640A-E/SN 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.
  • The 25LC640A-E/SN has a power-on reset circuit that initializes the device on power-up. During power-down, the device automatically goes into a low-power standby mode to conserve power.
  • The maximum clock frequency for the 25LC640A-E/SN is 3.4 MHz.
