3. Package and Pinout
Both devices are available in 8-pin SOP and 8-WSON packages with similar footprints. Pinout
definitions are identical with the two exceptions shown in Table 3-2. Where Macronix has a
RESET#/SIO3 pin, Micron has either a HOLD#/DQ3 or a RESET#/DQ3 pin. If the Micron device
has a RESET# pin, then the devices are pin compatible. If the Micron device has a HOLD# pin,
but the HOLD# function is not used, then the devices are also pin compatible. Macronix does
not support the VPP (10V Fast Programming Voltage) function available on Micron’s
W#/VPP/DQ2 pin. This function is normally only used on external programmers to accelerate
Program/Erase operations and is generally not used for “in-circuit” programming. Please consult
the latest Macronix datasheet for any possible package additions.

4. Key Feature and Operational Differences
4-1 Status Register and Configuration Register Differences
Both devices use registers to control device behavior and report status. The registers and bits
used are similar but not identical. Both the Micron and Macronix devices use BP bits to select
groups of memory areas for protection.
The N25Q032/64A Block Protection bits BP[2:0] are located in Status Register (bits [4:2]). The
Top/Bottom bit is located in Status Register bit 5 and selects whether block protection starts at
the top or bottom of memory. The BP[2:0] and Top/Bottom bits are nonvolatile and
reprogrammable.
The MX25U32/6435F Block Protection bits BP[3:0] are located in Status Register bits [5:2]. The
block protection starts at the top of memory, and the protected upper areas are the same. The
BP[3:0] bits are all nonvolatile and reprogrammable. The granularity of Write protection is
different between the Macronix and Micron devices if block protection starts at the bottom of
memory, but the same if protection starts at the top of memory.
4-2 QPI Differences
Micron’s Quad I/O mode is entered by setting a bit in the Nonvolatile Configuration Register
(NVCR), which remembers this mode after power cycles, or by setting a bit in the Enhanced
Volatile Configuration Register (VCR) and is reset after a power cycle.
The MX25U32/6435F requires an EQIO (35h) command to enter the equivalent QPI mode. This
mode can be terminated by a RSTQIO (F5h) command or by a power cycle or software reset.
4-3 XIP Differences
The XIP (eXecute In Place) feature (Macronix refers to this as Performance Enhance Mode) is
only used during Fast Read operations and eliminates the need to input read commands prior to
entering an address and reading data. This is an overhead reduction feature that increases data
throughput. Both devices offer this feature, but entry and exit methods are different.

APPLICATION NOTE

with Macronix MX25U3235F / MX25U6435F
4-4 Individual Sector Protection Differences
Both devices have the ability to write protect individual 64KB sectors/blocks of memory.
Individual Sector Protection does not use the nonvolatile BP bits in the Status Register. With the
Micron flash, it is possible to use both methods of write protection (BP bits and Individual Sector
Protection) simultaneously, and the protected area is the combination of the two. When using
the Macronix flash, either BP bit Protection or Individual Sector Protection can be selected
exclusively, with the default being the use of the BP bits.
The N25Q_A have one volatile Lock Register for each 64KB sector to control the sector’s
program/erase protection status. The protection can be turned on or off at any time unless the
sector’s Lock Register has been locked by the application. Once locked, its associated sector
will remain in the protected or unprotected state until the next power cycle or reset. All sectors
not protected by the Status Register BP configuration will be unprotected after power up and all
Lock Registers will be unlocked.
The MX25U_35F have one volatile protection register for each of the top sixteen 4KB sectors,
bottom sixteen 4KB sectors, and the remaining middle 64KB blocks (the MX25U3235F has 62
middle blocks and the MX25U6435F has 126 middle blocks). These protection registers can
only be used after permanently disabling the Status Register BP protection bits. This is done by
executing the WPSEL instruction once. Please note that this irreversible and Individual Sector
Protection method will be permanently selected.
After permanently selecting the Individual Sector Protection method for the MX25U_35F, all
sectors and blocks will be locked by default on power up. Sectors/blocks must be unlocked
before they can be programmed or erased. Unlocking sectors/blocks can be done on an
individual basis with the SBULK (Single Block Unlock) command or on all sectors/blocks with
the GBULK (Global Block Unlock) command. Sectors and blocks can be relocked as necessary
with the SBLK (Single Block Lock) command or GBLK (Global Block Lock) command.
Since the smallest individual sector protection size in the N25Q_A is 64KB, if an application is
currently locking/unlocking the top and/or bottom 64KB sector(s), it will need to lock/unlock each
of the 16 top and/or bottom 4KB sectors in the MX25U_35F for equivalent results.

8. Summary
The Macronix MX25U3235F/6435F and Micron N25Q032/64A have similar commands,
functions, and features. The devices are command compatible for basic read, program, and
erase (4KB and 64KB) operations. The devices are essentially pin compatible if the HOLD#
function is not used. A more detailed analysis should be done if “special” functions such as XIP,
Suspend/Resume, or Accelerated Programming are used. If common features are used in
standard traditional modes, they may need only minimal software modification.
