Introduction This application note indicates the differences between MX25L4026E and MX25L4025A/MX25L4025C. In Single I/O mode, MX25L4026E is identical in forms and functions with the MX25L4025A & MX25L4025C. MX25L4026E is capable of Dual Output mode (Single Input / Dual Output) but no longer supports Dual Input / Dual Output mode. The comparison and features of new products are described as below. The information provided is based on the data available at the time. The MX25L4026E datasheet may override this application note if there is a difference description for the same in the datasheet.
