APPLICATION NOTE
Comparison of MX25L3233F/73F and MX25L32xxD/xxE
1. Introduction
This application note compares Macronix 75nm 32Mb 3V Serial NOR Flash MX25L3233F with Macronix
110nm flash MX25L3235E and MX25L3206/8E and Macronix 150nm flash MX25L32xxD. Generally, the
MX25L3233F is backward compatible with the MX25L32xxD/xxE as it is pin and command compatible with
the basic Read/Program/Erase commands. There may be some differences if special features are used such
as using QPI mode commands, Write Protection, or CP mode programming.
The comparison covers the general features, performance, command codes, and other differences. The
document does not provide detailed information on individual devices, but highlights major differences. The
information in this document is based on the latest datasheets listed in "9. Reference". Newer versions of the
datasheets may override the contents of this document.
2. General Features
Macronix 3V 32Mb serial flash families have similar features and functions as shown in "Table 2-1. Key
Features Comparison".

The MX25L3233F Status Register bits are backward compatible with the registers of the MX25L32xxD/E,
with the exception of the MX25L3225D which has volatile bits which default with the memory array protected
at power-up.

cycles when executing a 4Read command. If the default number of dummy cycles is used, then this difference
can be ignored.

7. Data Protection
7-1. BP bit Block Protection
All of the listed Macronix flash use BP bits to select groups of memory areas for write protection.
The MX25L3233F/73F and MX25L3235E/39E/73 have the ability to write protect identical groups of blocks
with the same BP bit settings. Most of the regions protected by the MX25L3206E/08E and MX25L32xxD can
be protected by the MX25L3233F ("Table 7-1: Block Protection (BP) with T/B bit = 0").

7-2. Individual Sector Protection
The MX25L3235E/39E/73E has the ability to protect individual 4KB and 64KB sectors and blocks of memory.
The MX25L3233F and MX25L3206E do not support this feature.

10.Summary
Generally, the MX25L3233F is backward compatible with the MX25L32xxD/xxE as it is pin and command
compatible with the basic Read/Program/Erase commands. There may be some differences if special
features are used such as using QPI mode commands, Write Protection, or CP mode programming.
