AT25SF321B-SHB-B Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the AT25SF321B-SHB-B is 2.3V to 3.6V.
  • When the device is busy, it will ignore any incoming write requests. It's recommended to poll the WIP (Write In Progress) bit in the status register to check if the device is busy before initiating a page write operation.
  • The WP# (Write Protect) pin is used to prevent accidental writes to the device. When the WP# pin is low, the entire memory array is write-protected. To use it, connect the WP# pin to VCC or a logic high level to enable write operations, or connect it to GND or a logic low level to disable write operations.
  • To perform a sector erase operation, send the Sector Erase command (0x20) followed by the sector address. The device will then erase the entire sector. Note that sector erase operations can take up to 2 seconds to complete.
  • The AT25SF321B-SHB-B supports up to 100,000 erase cycles per sector.
