Instructions for Use:

1. Power Supply: Ensure the supply voltage (Vcc) is within the specified range of 2.5V to 5.5V.
2. Initialization: Before performing any read or write operations, initialize the device by applying the correct power supply and ensuring the chip select (CS) pin is set appropriately.
3. Read Operation: To read data, ensure CS is low, then apply the appropriate address and clock signals. Data can be read on the rising edge of the clock signal.
4. Write Operation: Writing data requires CS to be low, followed by sending the write command, address, and data bits. The write cycle takes up to 5ms to complete.
5. Standby Mode: Set CS high to enter standby mode, reducing power consumption to 1渭A.
6. Temperature Considerations: Operate within the temperature range of -40掳C to +85掳C to ensure reliable performance.
7. Data Integrity: For long-term data storage, this device guarantees data retention for up to 100 years under proper operating conditions.
