AT45DB021B-SC Frequently Asked Questions (FAQ)
-
The AT45DB021B-SC has a minimum of 100,000 erase cycles per sector, and a total of 2,000,000 erase cycles for the entire device.
-
To avoid page write buffer underrun or overrun errors, ensure that the page write buffer is completely filled or emptied before initiating a page write operation. Also, use the status register to monitor the page write buffer status and adjust the write operation accordingly.
-
After power-up, the AT45DB021B-SC should be initialized by performing a software reset (by writing the reset command to the command register) followed by a read of the device ID to verify the device is functioning correctly.
-
The AT45DB021B-SC does not support simultaneous read and write operations. To avoid data corruption, ensure that all write operations are completed before initiating a read operation, and vice versa.
-
The sector protection feature in the AT45DB021B-SC allows specific sectors to be protected from accidental erase or write operations, ensuring that critical data is preserved.
