AT25DF321A-SH-B Frequently Asked Questions (FAQs)

  • The AT25DF321A-SH-B has a minimum of 100,000 erase cycles, but the actual number of cycles may vary depending on the usage and operating conditions.
  • The hold pin (HOLD#) is used to pause the serial communication between the microcontroller and the flash memory. When the HOLD# pin is low, the serial communication is paused, and when it is high, the communication resumes. You should connect the HOLD# pin to the microcontroller's hold signal or a GPIO pin to control the hold function.
  • The recommended power-up sequence is to apply the power supply voltage (VCC) first, followed by the clock signal (SCK), and then the chip select signal (CS#). This ensures that the device is properly initialized and ready for operation.
  • The WP# pin is used to protect the status register from being written. When the WP# pin is low, the status register is write-protected, and when it is high, the status register can be written. You should connect the WP# pin to a GPIO pin or a pull-up resistor to control the write protection.
  • The maximum clock frequency for the AT25DF321A-SH-B is 50 MHz. However, the actual clock frequency may vary depending on the system design and operating conditions.
