APPLICATION NOTE Comparison of MX25L6435E and MX25L6465E 1. Introduction This application note compares MX25L6435E and MX25L6465E. The document does not provide detailed information on individual device, but highlights the similarities and differences between them. The comparison covers the general features, performance, command sets and device ID. MX25L6435E supports Dual Output mode (1I/2O: Single input / Dual output) and Quad Output mode (1I/4O: Single input / Quad output). MX25L6435E supports T/B (Top/Bottom) bit new function. However, MX25L6435E does not support DTR mode. The information provided is based on the data available at the time. MX25L6435E and MX25L6465E datasheets may override this application note if there is a different description for the same specification in the datasheets. Please refer to the contents and comparison tables below for more details. Publication Number: AN142V1 1 Issued: FEB. 23, 2012 APPLICATION NOTE 2. General Features 2-1. Feature Comparison MX25L6435E has a new T/B (Top/Bottom) bit configuration register. By the control of T/B bit, Block protect area by BP bit can be started from Top or Bottom of the memory array. For the differences between these products, please check the comparison tables below for details. Table 2-1.
