AT25DN256-SSHF-B Frequently Asked Questions (FAQs)

  • The AT25DN256-SSHF-B has a minimum of 100,000 write cycles per sector, with a total of 4,096 sectors. This means the total number of write cycles is approximately 409,600,000.
  • The AT25DN256-SSHF-B uses a page write buffer to handle page writes. The buffer is 128 bytes, and the device can perform a page write in 1.4 ms (typical) or 3.4 ms (maximum).
  • The WP# (Write Protect) pin is used to prevent writes to the status register and the memory array. When the WP# pin is low, the device is in write-protect mode, and writes to the status register and memory array are inhibited.
  • The AT25DN256-SSHF-B 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 AT25DN256-SSHF-B has an operating temperature range of -40°C to +85°C, making it suitable for use in a wide range of industrial and commercial applications.
