Comparison of MX25L6433F/73F and MX25L64xxE
1. Introduction
This application note compares Macronix 75nm 64Mb Serial NOR Flash MX25L6433F with Macronix
MX25L64xxE 110nm Serial flash. Generally, the MX25L6433F is backward compatible with the MX25L64xxE
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 DTR mode, Write Protection, or CP mode programming.
The document does not provide detailed information on the individual devices, but highlights the major
similarities and differences between them. The comparison covers the general features, performance,
command codes and other differences.
The information in this document is based on datasheets listed in "9. References". Newer versions of the
datasheets may override the contents of this document.
2. General Features
Macronix 3V 64Mb serial flash families have similar features and functions as shown in "Table 2-1: Key
Features Comparison".

7. Data Protection
7-1. BP bit Block Protection
All of these 64Mb Macronix flash can use BP bits in the Status Register to select groups of memory areas for write
protection. While the MX25L6433F/73F and MX25L6435E/73E/39E have the ability to write protect identical groups of
blocks with the same BP bit settings, they have a finer granularity of block protection than the MX25L6406E/45E/36E.
Most of the regions protected by the MX25L6406E/45E/36E can be protected by the MX25L6433F ("Table 7-1: Block
Protection (BP) with T/B bit = 0").

Notes:
1. The device is ready to accept a Chip Erase instruction if, and only if, all Block Protect (BP3, BP2, BP1, BP0) are 0.
2. The T/B bit = 1 condition is not shown, as MX25L6406E/6445E/6436E do not have T/B bit.

7-2. Individual Sector Protection
All of the listed 64Mb flash have the ability to protect individual 4KB and 64KB sectors and blocks of memory,
with the exception of the MX25L6433F/73F and MX25L6406E which do not support this feature.
8. Device Identification
The RDID instruction is for reading the 1-byte Manufacturer ID followed by the 2-byte Device ID. The REMS
instruction provides both the JEDEC assigned manufacturer ID and the specific Device ID.
Manufacturer and Device IDs have not changed ("Table 8-1: ID Code Comparison").
