Introduction This application note indicates the differences between MX25L2026E and MX25L2025/MX25L2025C. In Single I/O mode, MX25L2026E is identical in forms and functions with the MX25L2025 / MX25L2025C. MX25L2026E 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 MX25L2026E datasheet may override this application note if there is a difference description for the same in the datasheet.
