Migrating to MX25L4026E from MX25L4025A and MX25L4025C
1. 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.

2. General Features
2-1: Feature Comparison
The Dual Output mode (1I/2O) is one of the new features of the MX25L4026E, and the most advanced
technique is that this new product accepts wide range of clock rate from DC (Direct Current)~ 86MHz
for frequency control from host system.
