Hello

I try to find out the difference between Reader Application M24LR04E and Reader Application M24LR16E when it comes to data reading.

As far as I understood both components (M24LR04E and M24LR16E) operate with identic commands.

In my case I only want to read data from block 0x000 to 0x00F. On both components exist the requested memory range. Further I do not use any password protection.

When I read data from M24LR16E with Reader Application M24LR04E all what I get back is just ''no Tag answer''.

Why only M24LR16E works with Reader Application M24LR16E and not with Reader Application M24LR04E? Where is the difference?
