We ordered some DS1302ZN. However, the N was not printed right after the part number on the top mark of the chip. Did we order the wrong model number? Or was there a new version from the factory?

Question

Accepted Answer

The N on the top mark of DS1302 does not always follow right after the part number. It is explained in the datasheet that an N anywhere on the top mark indicates an industrial temperature grade device.
