Hello johnwasser !

Thank your for your reply.

If I change the adress 0x57 to 0x53 I have no reply from my device.

with 0x57

255...
255...
255...

In that case, the write function do not work.
I have already changed my function to integrate the write protection. If I present the password (Redirect Notice)

void  M24LR16E_write(int adress){


int ad=2304;

    Wire.beginTransmission(0x53);
    Wire.write((int)(ad >> 8));   // MSB
  Wire.write((int)(ad & 0xFF));


  Wire.write((byte)0x00);
  Wire.write((byte)0x00);
  Wire.write((byte)0x00);
  Wire.write((byte)0x00);

  Wire.write((byte)0x09);

  Wire.write((byte)0x00);
  Wire.write((byte)0x00);
  Wire.write((byte)0x00);
  Wire.write((byte)0x00);
  Wire.endTransmission(); 
  
    Wire.beginTransmission(0x53);
    Wire.write((int)(adress >> 8));   // MSB
  Wire.write((int)(adress & 0xFF));
   Wire.write((byte)0x00);
  Wire.endTransmission();
  }
