Instructions for Use
Power Supply:
- Connect VCC to the positive supply voltage (1.7V to 5.5V).
- Connect GND to the ground.
Addressing:
- Set the device address by connecting A0, A1, and A2 to either VCC 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.
Write Protect:
- Connect the WP pin to GND to enable writing to the memory.
- Connect the WP pin to VCC to disable writing (write protect).
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 VCC.
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.
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.
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.
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.
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.
