Instructions for Use

1. Power Supply:

   • Connect V_CC to the positive supply voltage (1.7V to 5.5V).
   • Connect GND to the ground.

2. Addressing:

   • Set the device address by connecting A0, A1, and A2 to either V_CC or GND. The address is determined by the binary combination of these pins.
   • Example: A0 = GND, A1 = GND, A2 = GND sets the device address to 0x50.

3. Write Protect:

   • Connect the WP pin to GND to enable writing to the memory.
   • Connect the WP pin to V_CC to disable writing (write protect).

4. I²C Communication:

   • Connect SDA (Serial Data Line) and SCL (Serial Clock Line) to the I²C bus.
   • Ensure pull-up resistors are connected to SDA and SCL lines to V_CC.

5. Reading Data:

   • Initiate a start condition on the I²C bus.
   • Send the device address with the read bit set (e.g., 0x50 for address 0x50).
   • Read the data from the SDA line.
   • Send a stop condition to terminate the read operation.

6. Writing Data:

   • Initiate a start condition on the I²C bus.
   • Send the device address with the write bit set (e.g., 0x50 for address 0x50).
   • Send the memory address where the data will be written.
   • Send the data to be written.
   • Send a stop condition to terminate the write operation.

7. Page Write:

   • Up to 32 bytes can be written in a single page write operation.
   • Ensure that the write time (5 ms) is respected before initiating another write operation to the same page.

8. Endurance and Data Retention:

   • The device is rated for 1,000,000 write cycles.
   • Data retention is guaranteed for at least 100 years under specified operating conditions.

9. Handling Precautions:

   • Avoid exposing the device to excessive voltage, current, or temperature beyond the specified limits.
   • Use proper ESD (Electrostatic Discharge) protection when handling the device.
