AT45DQ321-SHF2B-T Frequently Asked Questions (FAQ)
-
The recommended operating voltage range for the AT45DQ321-SHF2B-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 tie the HOLD pin to VCC through a 1kΩ resistor.
-
The AT45DQ321-SHF2B-T has a maximum of 100,000 erase cycles per sector, with a total of 8192 sectors.
-
The optimal clock frequency depends on the specific application requirements. The AT45DQ321-SHF2B-T supports clock frequencies up to 66MHz, but it's recommended to start with a lower frequency (e.g., 10MHz) and adjust as needed to ensure reliable operation.
-
The WP (Write Protect) pin is used to prevent writes to the status register and the memory array. When the WP pin is pulled low, the device is in write-protect mode, and any write attempts will be ignored. It's recommended to tie the WP pin to VCC or use an external switch to control write protection.
