AT93C66B-XPD-T Frequently Asked Questions (FAQ)
-
The AT93C66B-XPD-T has a minimum of 100,000 write cycles, but the actual number of write cycles may vary depending on the usage and operating conditions.
-
The AT93C66B-XPD-T has a built-in POR circuit that resets the device during power-up. To handle POR, ensure that the power supply is stable and within the recommended operating range, and that the device is properly connected to the power supply and ground.
-
The recommended operating temperature range for the AT93C66B-XPD-T is -40°C to +85°C. Operating the device outside this range may affect its performance and reliability.
-
To implement a reliable write operation, ensure that the device is properly powered, the write cycle is within the recommended timing, and the data is written in a sequential manner. Also, use the built-in error detection and correction mechanisms, such as the cyclic redundancy check (CRC), to ensure data integrity.
-
The WP pin is used to prevent accidental writes to the device. When the WP pin is tied to VCC, the device is in write-protect mode, and any write attempts will be ignored. When the WP pin is tied to GND, the device is in normal operation mode, and writes are allowed.
