Instructions:
- Power Supply: Ensure the supply voltage (Vcc) is within the specified range of 2.7 V to 3.6 V.
- SPI Configuration: Configure the SPI settings according to the device datasheet. The device supports up to 108 MHz clock frequency.
- Initialization: After power-up, initialize the device by sending the appropriate SPI commands.
- Read Operations: Use standard read commands to access data from the memory.
- Write Operations: Before writing, ensure the device is not write-protected and perform an erase operation if necessary.
- Protection: Utilize the WP pin to prevent accidental writes and the HOLD pin to pause operations.
- Temperature Considerations: Operate within the specified temperature range to ensure reliable performance.
- Endurance Management: Be mindful of the endurance limit and manage write/erase cycles accordingly.
- Data Retention: For long-term storage, consider environmental factors that may affect data retention.
For detailed command sets and timing diagrams, refer to the manufacturer’s datasheet.
