Instructions for Use
Power Supply:
- Connect the VCC pin to the power supply within the specified voltage range (1.7V to 5.5V).
- Connect the GND pin to the ground.
I2C Communication:
- Connect the SDA (Serial Data) and SCL (Serial Clock) pins to the corresponding I2C lines on your microcontroller.
- Ensure pull-up resistors are connected to the SDA and SCL lines to VCC. Typical values are 4.7kΩ to 10kΩ.
Write Protection:
- To enable write protection, connect the WP (Write Protect) pin to VCC.
- To disable write protection, connect the WP pin to GND or leave it floating.
Addressing:
- The device has a 7-bit I2C address, which can be configured using the A0, A1, and A2 pins. Refer to the datasheet for specific address configurations.
Reading Data:
- Initiate a start condition on the I2C bus.
- Send the device address with the read bit set.
- Read the desired number of bytes from the memory.
- Send a stop condition to end the read operation.
Writing Data:
- Initiate a start condition on the I2C bus.
- Send the device address with the write bit set.
- Send the memory address where data will be written.
- Send the data to be written.
- Send a stop condition to end the write operation.
- Wait for the write cycle to complete before initiating another write operation. This typically takes 5 μs.
Data Retention:
- Ensure that the device is not exposed to excessive heat or radiation to maintain data retention over the specified period.
Handling:
- Handle the device with care to avoid static damage. Use proper ESD precautions.
Storage:
- Store the device in a dry, cool place to ensure long-term reliability.
