Instructions for Use
Power Supply:
- Connect Vcc to the positive supply voltage (2.7 V to 5.5 V).
- Connect GND to the ground.
Addressing:
- The device has a 7-bit I2C address, which can be set by the A0, A1, and A2 pins. Refer to the datasheet for specific address configurations.
Write Protect:
- To enable write protection, connect the WP pin to Vcc. To disable write protection, connect the WP pin to GND.
I2C Communication:
- The SDA (Data) and SCL (Clock) lines must be connected to the I2C bus.
- Ensure pull-up resistors are used on both SDA and SCL lines to Vcc.
Read Operation:
- Start with a START condition.
- Send the 7-bit I2C address followed by a read bit (1).
- The EEPROM will send the data byte.
- Acknowledge or NACK the data byte as needed.
- End with a STOP condition.
Write Operation:
- Start with a START condition.
- Send the 7-bit I2C address followed by a write bit (0).
- Send the memory address where data will be written.
- Send the data byte(s) to be written.
- End with a STOP condition.
Data Retention:
- Ensure the device is not exposed to excessive heat or radiation, which can affect data retention.
Handling:
- Handle the device with care to avoid static damage. Use ESD protection when handling.
Storage:
- Store the device in a dry, cool place to prevent moisture damage.
For detailed timing diagrams and more specific information, refer to the full datasheet provided by the manufacturer.
