AT45DQ161-SHFHB-T Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the AT45DQ161-SHFHB-T is 2.7V to 3.6V, with a typical voltage of 3.3V.
  • The HOLD pin should be pulled high during power-up and power-down sequences to prevent unwanted writes or erases. It's recommended to connect a pull-up resistor to the HOLD pin and tie it to VCC.
  • The AT45DQ161-SHFHB-T has a maximum of 10,000 erase cycles per sector, with a total of 16,384 sectors. This means the device can withstand a total of approximately 163,840,000 erase cycles.
  • The optimal clock frequency depends on the specific application and system requirements. The AT45DQ161-SHFHB-T supports clock frequencies up to 66 MHz, but it's recommended to start with a lower frequency (e.g., 10 MHz) and adjust as needed to ensure reliable operation.
  • The WP pin is used to prevent accidental writes or erases. When the WP pin is pulled low, the device enters a write-protected state, and any write or erase operations are inhibited. To use the WP pin, connect it to VCC or GND depending on the desired state.
