APPLICATION NOTE Migrating to MX25V512E from MX25V512/512C 1. Introduction This application note is the migration guide from the MX25V512/MX25V512C to the MX25V512E The MX25V512E is capable of Dual Output mode (Single Input / Dual Output). In most applications, the MX25V512E is backward compatible with the MX25V512/512C, respectively, and do not require any firmware or hardware modifications if the application continues to use them in Single I/O mode. The information provided is based on the data available at the time. The MX25V512E datasheets may override this application note if there is a different description for the same specifications in the datasheets. Please refer to the contents and comparison tables below for more details. Publication Number: AN165V1 1 Issued: JUN. 19, 2012 APPLICATION NOTE 2. General Feature 2-1. Feature Comparison The Dual Output mode (1I/2O) is one of the new features of the MX25V512E. The new devices also support clock rates up to 75MHz. Table 2-1.
