GENERAL DESCRIPTION
MX25L512E is a CMOS 524,288 bit serial Flash memory, which is configured as 65,536 x 8 internally. MX25L512E
features a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus
signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). Serial access to the device
is enabled by CS# input.
MX25L512E provides sequential read operation on whole chip.
After program/erase command is issued, auto program/erase algorithms which program/erase and verify the specified page or sector/block locations will be executed. Program command is executed on page (256 bytes) basis, and
erase command is executes on chip or sector (4K-bytes).
To provide user with ease of interface, a status register is included to indicate the status of the chip. The status read
command can be issued to detect completion status of a program or erase operation via WIP bit.
When the device is not in operation and CS# is high, it is put in standby mode and draws less than 25uA DC current.
The MX25L512E utilizes Macronix's proprietary memory cell, which reliably stores memory contents even after
100,000 program and erase cycles.

DATA PROTECTION
MX25L512E is designed to offer protection against accidental erasure or programming caused by spurious system
level signals that may exist during power transition. During power up the device automatically resets the state machine in the standby mode. In addition, with its control register architecture, alteration of the memory contents only
occurs after successful completion of specific command sequences. The device also incorporates several features
to prevent inadvertent write cycles resulting from VCC power-up and power-down transition or system noise.
• Valid command length checking: The command length will be checked whether it is at byte base and completed on byte boundary.
• Write Enable (WREN) command: WREN command is required to set the Write Enable Latch bit (WEL) before
other command to change data. The WEL bit will return to reset stage under following situation:
- Power-up
- Write Disable (WRDI) command completion
- Write Status Register (WRSR) command completion
- Page Program (PP) command completion
- Sector Erase (SE) command completion
- Block Erase (BE) command completion
- Chip Erase (CE) command completion
• Software Protection Mode (SPM): by using BP0-BP1 bits to set the part of Flash protected from data change.
• Hardware Protection Mode (HPM): by using WP# going low to protect the BP0-BP1 bits and SRWD bit from
data change.
• Deep Power Down Mode: By entering deep power down mode, the flash device also is under protected from
writing all commands except Release from Deep Power-down mode command (RDP) and Read Electronic Signature command (RES).

HOLD FEATURE
HOLD# pin signal goes low to hold any serial communications with the device. The HOLD feature will not stop the
operation of write status register, programming, or erasing in progress.
The operation of HOLD requires Chip Select(CS#) keeping low and starts on falling edge of HOLD# pin signal
while Serial Clock (SCLK) signal is being low (if Serial Clock signal is not being low, HOLD operation will not start
until Serial Clock signal being low). The HOLD condition ends on the rising edge of HOLD# pin signal while Serial Clock(SCLK) signal is being low(if Serial Clock signal is not being low, HOLD operation will not end until Serial
Clock being low), see Figure 1.

The Serial Data Output (SO) is high impedance, both Serial Data Input (SI) and Serial Clock (SCLK) are don't care
during the HOLD operation. If Chip Select (CS#) drives high during HOLD operation, it will reset the internal logic of
the device. To re-start communication with chip, the HOLD# must be at high and CS# must be at low.

DEVICE OPERATION
1. Before a command is issued, status register should be checked to ensure the device is ready for the intended
operation.
2. When incorrect command is inputted to this LSI, this LSI becomes standby mode and keeps the standby mode
until next CS# falling edge. In standby mode, SO pin of this LSI should be High-Z. The CS# falling time needs to
follow tCHCL spec. (Please refer to Table 6. AC CHARACTERISTICS)
3. When correct command is inputted to this LSI, this LSI becomes active mode and keeps the active mode until
next CS# rising edge. The CS# rising time needs to follow tCLCH spec. (Please refer to Table 6. AC CHARACTERISTICS)
4. Input data is latched on the rising edge of Serial Clock(SCLK) and data shifts out on the falling edge of SCLK.
The difference of Serial mode 0 and mode 3 is shown as Figure 2.
5. For the following instructions: RDID, RDSR, READ, FAST_READ, RDSFDP, DREAD, RES and REMS the shifted-in instruction sequence is followed by a data-out sequence. After any bit of data being shifted out, the CS#
can be high. For the following instructions: WREN, WRDI, WRSR, SE, BE, CE, PP, RDP and DP the CS# must
go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed.
6. During the progress of Write Status Register, Program, Erase operation, to access the memory array is neglected and not affect the current operation of Write Status Register, Program, and Erase.

COMMAND DESCRIPTION
(1) Write Enable (WREN)
The Write Enable (WREN) instruction is for setting Write Enable Latch (WEL) bit. For those instructions like PP, SE,
BE, CE, and WRSR, which are intended to change the device content, should be set every time after the WREN instruction setting the WEL bit.
The sequence of issuing WREN instruction is: CS# goes low→ sending WREN instruction code→ CS# goes high. (see
Figure 11)
(2) Write Disable (WRDI)
The Write Disable (WRDI) instruction is for resetting Write Enable Latch (WEL) bit.
The sequence of issuing WRDI instruction is: CS# goes low→ sending WRDI instruction code→ CS# goes high. (see
Figure 12)
The WEL bit is reset by following situations:
- Power-up
- Write Disable (WRDI) instruction completion
- Write Status Register (WRSR) instruction completion
- Page Program (PP) instruction completion
- Sector Erase (SE) instruction completion
- Block Erase (BE) instruction completion
- Chip Erase (CE) instruction completion
(3) Read Identification (RDID)
RDID instruction is for reading the manufacturer ID of 1-byte and followed by Device ID of 2-byte. The MXIC Manufacturer ID is C2(hex), the memory type ID is 20(hex) as the first-byte device ID, and the individual device ID of
second-byte ID is as followings: 10(hex) for MX25L512E.
The sequence of issuing RDID instruction is: CS# goes low→sending RDID instruction code→24-bits ID data out on
SO→to end RDID operation can use CS# to high at any time during data out. (see Figure. 13)
While Program/Erase operation is in progress, it will not decode the RDID instruction, so there's no effect on the cycle of program/erase operation which is currently in progress. When CS# goes high, the device is at standby stage.

REV. 1.1, FEB. 10, 2012
MX25L512E
(4) Read Status Register (RDSR)
The RDSR instruction is for reading Status Register Bits. The Read Status Register can be read at any time (even in
program/erase/write status register condition) and continuously. It is recommended to check the Write in Progress (WIP)
bit before sending a new instruction when a program, erase, or write status register operation is in progress.
The sequence of issuing RDSR instruction is: CS# goes low→sending RDSR instruction code→Status Register
data out on SO (see Figure. 14)
The definition of the status register bits is as below:
WIP bit. The Write in Progress (WIP) bit, a volatile bit, indicates whether the device is busy in program/erase/write
status register progress. When WIP bit sets to 1, which means the device is busy in program/erase/write status
register progress. When WIP bit sets to 0, which means the device is not in progress of program/erase/write status
register cycle.
WEL bit. The Write Enable Latch (WEL) bit, a volatile bit, indicates whether the device is set to internal write enable
latch. When WEL bit sets to 1, which means the internal write enable latch is set, the device can accept program/
erase/write status register instruction. When WEL bit sets to 0, which means no internal write enable latch; the device will not accept program/erase/write status register instruction.
BP1, BP0 bits. The Block Protect (BP1, BP0) bits, non-volatile bits, indicate the protected area(as defined in table
1) of the device to against the program/erase instruction without hardware protection mode being set. To write the
Block Protect (BP1, BP0) bits requires the Write Status Register (WRSR) instruction to be executed. Those bits
define the protected area of the memory to against Page Program (PP), Sector Erase (SE), Block Erase (BE) and
Chip Erase(CE) instructions (only if all Block Protect bits set to 0, the CE instruction can be executed)
SRWD bit. The Status Register Write Disable (SRWD) bit, non-volatile bit, is operated together with Write Protection (WP#) pin for providing hardware protection mode. The hardware protection mode requires SRWD sets to 1
and WP# pin signal is low stage. In the hardware protection mode, the Write Status Register (WRSR) instruction is
no longer accepted for execution and the SRWD bit and Block Protect bits (BP1, BP0) are read only.

(5) Write Status Register (WRSR)
The WRSR instruction is for changing the values of Status Register Bits. Before sending WRSR instruction, the
Write Enable (WREN) instruction must be decoded and executed to set the Write Enable Latch (WEL) bit in advance. The WRSR instruction can change the value of Block Protect (BP1, BP0) bits to define the protected area
of memory (as shown in table 1). The WRSR also can set or reset the Status Register Write Disable (SRWD) bit in
accordance with Write Protection (WP#) pin signal. The WRSR instruction cannot be executed once the Hardware
Protected Mode (HPM) is entered.
The sequence of issuing WRSR instruction is: CS# goes low→ sending WRSR instruction code→ Status Register
data on SI→ CS# goes high. (see Figure 15)
The WRSR instruction has no effect on b6, b5, b4, b1, b0 of the status register.
The CS# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed.
The self-timed Write Status Register cycle time (tW) is initiated as soon as Chip Select (CS#) goes high. The Write
in Progress (WIP) bit still can be check out during the Write Status Register cycle is in progress. The WIP sets 1
during the tW timing, and sets 0 when Write Status Register Cycle is completed, and the Write Enable Latch (WEL)
bit is reset.

change the values of SRWD, BP1, BP0. The protected area, which is defined by BP1, BP0, is at software
protected mode (SPM).
- When SRWD bit=1 and WP# is high, the WREN instruction may set the WEL bit can change the values of
SRWD, BP1, BP0. The protected area, which is defined by BP1, BP0, is at software protected mode (SPM)
Note: If SRWD bit=1 but WP# is low, it is impossible to write the Status Register even if the WEL bit has previously been set. It is rejected to write the Status Register and not be executed.
Hardware Protected Mode (HPM):
- When SRWD bit=1, and then WP# is low (or WP# is low before SRWD bit=1), it enters the hardware protected mode (HPM). The data of the protected area is protected by software protected mode by BP1, BP0
and hardware protected mode by the WP# to against data modification.
Note: to exit the hardware protected mode, it requires WP# driving high once the hardware protected mode is
entered. If the WP# pin is permanently connected to high, the hardware protected mode can never be entered; only can use software protected mode via BP1, BP0.

(6) Read Data Bytes (READ)
The read instruction is for reading data out. The address is latched on rising edge of SCLK, and data shifts out on
the falling edge of SCLK at a maximum frequency fR. The first address byte can be at any location. The address
is automatically increased to the next higher address after each byte data is shifted out, so the whole memory can
be read out at a single READ instruction. The address counter rolls over to 0 when the highest address has been
reached.
The sequence of issuing READ instruction is: CS# goes low→ sending READ instruction code→ 3-byte address on
SI→ data out on SO→ to end READ operation can use CS# to high at any time during data out. (see Figure. 16)
(7) Read Data Bytes at Higher Speed (FAST_READ)
The FAST_READ instruction is for quickly reading data out. The address is latched on rising edge of SCLK, and
data of each bit shifts out on the falling edge of SCLK at a maximum frequency fC. The first address byte can be at
any location. The address is automatically increased to the next higher address after each byte data is shifted out,
so the whole memory can be read out at a single FAST_READ instruction. The address counter rolls over to 0 when
the highest address has been reached.
The sequence of issuing FAST_READ instruction is: CS# goes low→ sending FAST_READ instruction code→
3-byte address on SI→ 1-dummy byte address on SI→data out on SO→ to end FAST_READ operation can use
CS# to high at any time during data out. (see Figure. 17)
While Program/Erase/Write Status Register cycle is in progress, FAST_READ instruction is rejected without any impact on the Program/Erase/Write Status Register current cycle.
(8) Dual Output Mode (DREAD)
The DREAD instruction enable double throughput of Serial Flash in read mode. The address is latched on rising
edge of SCLK, and data of every two bits(interleave on 1I/2O pins) shift out on the falling edge of SCLK at a maximum frequency fT. The first address byte can be at any location. The address is automatically increased to the next
higher address after each byte data is shifted out, so the whole memory can be read out at a single DREAD instruction. The address counter rolls over to 0 when the highest address has been reached. Once writing DREAD instruction, the following data out will perform as 2-bit instead of previous 1-bit.
The sequence is shown as Figure 18.
While Program/Erase/Write Status Register cycle is in progress, DREAD instruction is rejected without any impact
on the Program/Erase/Write Status Register current cycle.
The DREAD only performs read operation. Program/Erase /Read ID/Read status....operations do not support
DREAD throughputs.
(9) Sector Erase (SE)
The Sector Erase (SE) instruction is for erasing the data of the chosen sector to be "1". A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL) bit before sending the Sector Erase (SE). Any address
of the sector (see table 3) is a valid address for Sector Erase (SE) instruction. The CS# must go high exactly at the
byte boundary (the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not
executed.

Address bits [Am-A12] (Am is the most significant address) select the sector address.
The sequence of issuing SE instruction is: CS# goes low → sending SE instruction code→ 3-byte address on SI →
CS# goes high. (see Figure 20)
The self-timed Sector Erase Cycle time (tSE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be checked out during the Sector Erase cycle is in progress. The WIP sets 1 during the
tSE timing, and sets 0 when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the
page is protected by BP1, BP0 bits, the Sector Erase (SE) instruction will not be executed on the page.
(10) Block Erase (BE)
The Block Erase (BE) instruction is for erasing the data of the chosen block to be "1". A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL) bit before sending the Block Erase (BE). Any address
of the block (see table 3) is a valid address for Block Erase (BE) instruction. The CS# must go high exactly at the
byte boundary (the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not
executed.
The sequence of issuing BE instruction is: CS# goes low → sending BE instruction code→ 3-byte address on SI →
CS# goes high. (see Figure 21)
The self-timed Block Erase Cycle time (tBE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Sector Erase cycle is in progress. The WIP sets 1 during the
tBE timing, and sets 0 when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the
page is protected by BP1, BP0 bits, the Block Erase (BE) instruction will not be executed on the page.
(11) Chip Erase (CE)
The Chip Erase (CE) instruction is for erasing the data of the whole chip to be "1". A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL) bit before sending the Chip Erase (CE). Any address of the
sector (see table 3) is a valid address for Chip Erase (CE) instruction. The CS# must go high exactly at the byte
boundary( the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not executed.
The sequence of issuing CE instruction is: CS# goes low→ sending CE instruction code→ CS# goes high. (see
Figure 22)
The self-timed Chip Erase Cycle time (tCE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Chip Erase cycle is in progress. The WIP sets 1 during the tCE
timing, and sets 0 when Chip Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the chip is
protected by BP1, BP0 bits, the Chip Erase (CE) instruction will not be executed. It will be only executed when BP1,
BP0 all set to "0".
(12) Page Program (PP)
The Page Program (PP) instruction is for programming the memory to be "0". A Write Enable (WREN) instruction
must execute to set the Write Enable Latch (WEL) bit before sending the Page Program (PP). If the eight least significant address bits (A7-A0) are not all 0, all transmitted data which goes beyond the end of the current page are
programmed from the start address if the same page (from the address whose 8 least significant address bits (A7A0) are all 0). The CS# must keep during the whole Page Program cycle. The CS# must go high exactly at the
byte boundary( the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not

executed. If more than 256 bytes are sent to the device, the data of the last 256-byte is programmed at the request
page and previous data will be disregarded. If less than 256 bytes are sent to the device, the data is programmed at
the request address of the page without effect on other address of the same page.
The sequence of issuing PP instruction is: CS# goes low→ sending PP instruction code→ 3-byte address on SI→ at
least 1-byte on data on SI→ CS# goes high. (see Figure 19)
The self-timed Page Program Cycle time (tPP) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Page Program cycle is in progress. The WIP sets 1 during the
tPP timing, and sets 0 when Page Program Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the
page is protected by BP1, BP0 bits, the Page Program (PP) instruction will not be executed.
(13) Deep Power-down (DP)
The Deep Power-down (DP) instruction is for setting the device on the minimizing the power consumption (to entering the Deep Power-down mode), the standby current is reduced from ISB1 to ISB2). The Deep Power-down mode
requires the Deep Power-down (DP) instruction to enter, during the Deep Power-down mode, the device is not active and all Write/Program/Erase instruction are ignored. When CS# goes high, it's only in standby mode not deep
power-down mode. It's different from Standby mode.
The sequence of issuing DP instruction is: CS# goes low→ sending DP instruction code→ CS# goes high. (see Figure 22)
Once the DP instruction is set, all instruction will be ignored except the Release from Deep Power-down mode (RDP)
and Read Electronic Signature (RES) instruction. (RES instruction to allow the ID been read out). When Powerdown, the deep power-down mode automatically stops, and when power-up, the device automatically is in standby
mode. For RDP instruction the CS# must go high exactly at the byte boundary (the latest eighth bit of instruction
code been latched-in); otherwise, the instruction will not executed. As soon as Chip Select (CS#) goes high, a delay
of tDP is required before entering the Deep Power-down mode and reducing the current to ISB2.
(14) Release from Deep Power-down (RDP), Read Electronic Signature (RES)
The Release from Deep Power-down (RDP) instruction is terminated by driving Chip Select (CS#) High. When Chip
Select (CS#) is driven High, the device is put in the Stand-by Power mode. If the device was not previously in the
Deep Power-down mode, the transition to the Stand-by Power mode is immediate. If the device was previously in
the Deep Power-down mode, though, the transition to the Stand-by Power mode is delayed by tRES2, and Chip
Select (CS#) must remain High for at least tRES2(max), as specified in Table 6. Once in the Stand-by Power mode,
the device waits to be selected, so that it can receive, decode and execute instructions.
RES instruction is for reading out the old style of 8-bit Electronic Signature, whose values are shown as table of ID
Definitions. This is not the same as RDID instruction. It is not recommended to use for new design. For new deisng,
please use RDID instruction. Even in Deep power-down mode, the RDP and RES are also allowed to be executed,
only except the device is in progress of program/erase/write cycle; there's no effect on the current program/erase/
write cycle in progress.
The sequence is shown as Figure 24 and Figure 25.

The RES instruction is ended by CS# goes high after the ID been read out at least once. The ID outputs repeatedly if continuously send the additional clock cycles on SCLK while CS# is at low. If the device was not previously
in Deep Power-down mode, the device transition to standby mode is immediate. If the device was previously in
Deep Power-down mode, there's a delay of tRES2 to transit to standby mode, and CS# must remain to high at least
tRES2(max). Once in the standby mode, the device waits to be selected, so it can be received, be decoded, and be
executed instruction.
The RDP instruction is for releasing from Deep Power Down Mode.
(15) Read Electronic Manufacturer ID & Device ID (REMS)
The REMS instruction is an alternative to the Release from Power-down/Device ID instruction that provides both the
JEDEC assigned manufacturer ID and the specific device ID.
The REMS instruction is very similar to the Release from Power-down/Device ID instruction. The instruction is initiated by driving the CS# pin low and shift the instruction code "90h" followed by two dummy bytes and one bytes
address (A7~A0). After which, the Manufacturer ID for MXIC (C2h) and the Device ID are shifted out on the falling
edge of SCLK with most significant bit (MSB) first as shown in Figure 26. The Device ID values are listed in Table of
ID Definitions. If the one-byte address is initially set to 01h, then the device ID will be read first and then followed by
the Manufacturer ID. The Manufacturer and Device IDs can be read continuously, alternating from one to the other.
The instruction is completed by driving CS# high.

(16) Read SFDP Mode (RDSFDP)
The Serial Flash Discoverable Parameter (SFDP) standard provides a consistent method of describing the functional
and feature capabilities of serial flash devices in a standard set of internal parameter tables. These parameter tables
can be interrogated by host system software to enable adjustments needed to accommodate divergent features
from multiple vendors. The concept is similar to the one found in the Introduction of JEDEC Standard, JESD68 on
CFI.
The sequence of issuing RDSFDP instruction is CS# goes low→send RDSFDP instruction (5Ah)→send 3 address
bytes on SI pin→send 1 dummy byte on SI pin→read SFDP code on SO→to end RDSFDP operation can use CS#
to high at any time during data out.
SFDP is a standard of JEDEC. JESD216. v1.0.

Note 1: h/b is hexadecimal or binary.
Note 2: (x-y-z) means I/O mode nomenclature used to indicate the number of active pins used for the opcode (x),
address (y), and data (z). At the present time, the only valid Read SFDP instruction modes are: (1-1-1), (2-2-2),
and (4-4-4)
Note 3: Wait States is required dummy clock cycles after the address bits or optional mode bits.
Note 4: Mode Bits is optional control bits that follow the address bits. These bits are driven by the system controller
if they are specified. (eg,read performance enhance toggling bits)
Note 5: 4KB=2^0Ch,32KB=2^0Fh,64KB=2^10h
Note 6: 0xFFh means all data is blank ("1b").

POWER-ON STATE
The device is at the states as below when power-up:
- Standby mode (please note it is not deep power-down mode)
- Write Enable Latch (WEL) bit is reset
The device must not be selected during power-up and power-down stage unless the VCC achieves below correct
level (Please refer to the figure of "power-up timing"):
- VCC minimum at power-up stage and then after a delay of tVSL
- GND at power-down
Please note that a pull-up resistor on CS# may ensure a safe and proper power-up/down level.
An internal Power-On Reset (POR) circuit may protect the device from data corruption and inadvertent data change
during power up state.
For further protection on the device, if the VCC does not reach the VCC minimum level, the correct operation is not
guaranteed. The read, write, erase, and program command should be sent after the time delay: tVSL after VCC
reached VCC minimum level. Please refer to the figure of "power-up timing".
The device can accept read command after VCC reached VCC minimum and a time delay of tVSL.
Note:
- To stabilize the VCC level, the VCC rail decoupled by a suitable capacitor close to package pins is recommended.(generally around 0.1uF)
