Migrating MX25L3235D to MX25L3235E

APPLICATION NOTE
Migrating to MX25L3235E from MX25L3235D
1. Introduction
This application note introduces the related notices for migrating to MX25L3235E from MX25L3235D.
The document does not provide detailed information on individual devices, but highlights the similarities
and differences between them. The comparison covers the general features, performance, command
sets and device ID.
MX25L3235E supports new features, such as 1I/2O: single-input/dual-output, 1I/4O: single-input/quadoutput, HOLD# feature, software reset, SFDP, TB (Top/Bottom) bit configuration register and individual
sector/block protection mode etc.
The information provided is based on the data available at the time the document is released.
MX25L3235E datasheet may override this application note if there are content differences in the latest
datasheet.
Please refer to the contents and comparison tables below for more details.

2. General Features
2-1. Feature Comparison
MX25L3235E supports 1I/2O (single-input/dual-output) and 1I/4O (single-input/quad-output) new
features, which provide faster read speed than former product.
MX25L3235E has a new TB (Top/Bottom) bit configuration register. By the control of TB bit, Block
protect area by BP bit can be started from Top or Bottom of the memory array.
MX25L3235E supports the SFDP feature, which provides a consistent method of describing the
features and functional capabilities of this Serial Flash device. User or host system can read the SFDP
to understand the capabilities of the MX25L3235E for more efficient control.
HOLD#, software reset, and individual sector/block protection features of MX25L3235E provide user
additional methods to control memory.
For the differences between these products, please check the comparison tables below for the detail.
