Instructions for 25LC160

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the range of 2.0V to 5.5V.

2. Initialization:

   • Before performing any operations, initialize the device by applying the correct power supply and ensuring the SPI interface is properly configured.

3. Reading Data:

   • Use the Read command to access data from the memory. The address from which to read should be specified in the command sequence.

4. Writing Data:

   • To write data, first issue a Write Enable command. Then use the Write command with the target address and data bytes. Each write operation can write up to one page (64 bytes).

5. Erase Operations:

   • For sector erase, use the Sector Erase command specifying the starting address of the sector to be erased. Note that each sector is 4K bits.

6. Status Check:

   • After write or erase operations, check the status register to ensure the operation has completed successfully before initiating another operation.

7. Standby Mode:

   • To minimize power consumption, place the device in standby mode when not actively reading or writing.

8. Data Protection:

   • Utilize the write protect pin to prevent accidental writes or erases during critical operations.

9. Temperature Considerations:

   • Be aware of operational temperature limits to avoid damage or unreliable performance.

10. Endurance and Retention:

    • The device supports a minimum of 20 years of data retention and can endure multiple write cycles as specified in the datasheet.
