Uniform SECTOR Dual and Quad Serial Flash
Device Operation
SPI Mode
Standard SPI
The ACE25C320G features a serial peripheral interface on 4 signals bus: Serial Clock (SCLK), Chip
Select (CS#), Serial Data Input (SI) and Serial Data Output (SO). Both SPI bus mode 0 and 3 are
supported. Input data is latched on the rising edge of SCLK and data shifts out on the falling edge of
SCLK.
Dual SPI
The ACE25C320G supports Dual SPI operation when using the “Dual Output Fast Read” and “Dual
I/O Fast Read” (3BH and BBH) commands. These commands allow data to be transferred to or from
the device at two times the rate of the standard SPI. When using the Dual SPI command the SI and
SO pins become bidirectional I/O pins: IO0 and IO1.
Quad SPI
The ACE25C320G supports Quad SPI operation when using the “Quad Output Fast Read”,” Quad
I/O Fast Read”, “Quad I/O Word Fast Read” (6BH, EBH, E7H) commands. These commands allow
data to be transferred to or from the device at four times the rate of the standard SPI. When using the
Quad SPI command the SI and SO pins become bidirectional I/O pins: IO0 and IO1, and WP# and
HOLD# pins become IO2 and IO3. Quad SPI commands require the non-volatile Quad Enable bit (QE)
in Status Register to be set.
Hold
The HOLD# signal goes low to stop any serial communications with the device, but doesn’t stop the
operation of write status register, programming, or erasing in progress.
The operation of HOLD, need CS# keep low, and starts on falling edge of the HOLD# signal, with
SCLK signal being low (if SCLK is not being low, HOLD operation will not start until SCLK being low).
The HOLD condition ends on rising edge of HOLD# signal with SCLK being low (If SCLK is not being
low, HOLD operation will not end until SCLK being low).
The SO is high impedance, both SI and SCLK don’t care during the HOLD operation, if 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 then CS# must be at low.

Data Protection (The ACE25C320G provide the following data protection methods:)
 Write Enable (WREN) command: The WREN command is set the Write Enable Latch bit (WEL).
The WEL bit will return to reset by the following situation:
-Power-Up
-Write Disable (WRDI)
-Write Status Register(WRSR)
-Page Program (PP)
-Sector Erase (SE) / Block Erase (BE) / Chip Erase (CE)
 Software Protection Mode: The Block Protect (SEC, TB, BP2, BP1, BP0) bits define the section
of the memory array that can be read but not change.
 Hardware Protection Mode: WP# going low to protected the BP0~SEC bits and SRP0~1 bits.
 Deep Power-Down Mode: In Deep Power-Down Mode, all commands are ignored except the
Release from deep Power-Down Mode command.

ACE25C320G
Uniform SECTOR Dual and Quad Serial Flash
WIP bit
The Write In Progress (WIP) bit indicates whether the memory is busy in program/erase/write status
register progress. When WIP bit sets to 1, means the device is busy in program/erase/write status
register progress, when WIP bit sets 0, means the device is not in program/erase/write status register
progress.
WEL bit
The Write Enable Latch (WEL) bit indicates the status of the internal Write Enable Latch. When set to
1 the internal Write Enable Latch is set, when set to 0 the internal Write Enable Latch is reset and no
Write Status Register, Program or Erase command is accepted.
SEC, TB, BP2, BP1, BP0 bits
The Block Protect (SEC, TB, BP2, BP1, BP0) bits are non-volatile. They define the size of the area to
be software protected against Program and Erase commands. These bits are written with the Write
Status Register (WRSR) command. When the Block Protect (SEC, TB, BP2, BP1, BP0) bits are set to
1, the relevant memory area (as defined in Table1).becomes protected against Page Program (PP),
Sector Erase (SE) and Block Erase (BE) commands. The Block Protect (SEC, TB, BP2, BP1, BP0)
bits can be written provided that the Hardware Protected mode has not been set. The Chip Erase (CE)
command is executed, if the Block Protect (BP2, BP1, BP0) bits are “000” when CMP=0, or “110/111”
when CMP=1.
SRP1, SRP0 bits.
The Status Register Protect (SRP1 and SRP0) bits are non-volatile Read/Write bits in the status
register. The SRP bits control the method of write protection: software protection, hardware protection,
power supply lock-down or one time programmable protection.

QE bit.
The Quad Enable (QE) bit is a non-volatile Read/Write bit in the Status Register that allows Quad
operation. When the QE bit is set to 0 (Default) the WP# pin and HOLD# pin are enable. When the QE
pin is set to 1, the Quad IO2 and IO3 pins are enabled. (The QE bit should never be set to 1 during
standard SPI or Dual SPI operation if the WP# or HOLD# pins are tied directly to the power supply or
ground)
LB3/LB2/LB1 bit.
The LB bit is a non-volatile One Time Program (OTP) bit in Status Register (S10) that provide the
write protect control and status to the Security Registers. The default state of LB is 0, the security
registers are unlocked. LB can be set to 1 individually using the Write Register instruction. LB is One
Time Programmable, once it’s set to 1, the Security Registers will become read-only permanently.
LB0 is reserved, LB3/2/1 for Security Registers 3:1.
CMP bit
The CMP bit is a non-volatile Read/Write bit in the Status Register (S14). It is used in conjunction the
SEC-BP0 bits to provide more flexibility for the array protection. Please see the Status registers
Memory Protection table for details. The default setting is CMP=0.
SUS bit
The SUS bit is a read only bit in the status register (S15 ) that is set to 1 after executing an
Erase/Program Suspend (75H) command. The SUS bit is cleared to 0 by Erase/Program Resume
(7AH) command as well as a power-down, power-up cycle.
Commands Description
All commands, addresses and data are shifted in and out of the device, beginning with the most
significant bit on the first rising edge of SCLK after CS# is driven low. Then, the one-byte command
code must be shifted in to the device, most significant bit first on SI, each bit being latched on the
rising edges of SCLK.
See Table2, every command sequence starts with a one-byte command code. Depending on the
command, this might be followed by address bytes, or by data bytes, or by both or none. CS# must be
driven high after the last bit of the command sequence has been shifted in. For the command of Read,
Fast Read, Read Status Register or Release from Deep Power-Down, and Read Device ID, the
shifted-in command sequence is followed by a data-out sequence. CS# can be driven high after any
bit of the data-out sequence is being shifted out.
For the command of Page Program, Sector Erase, Block Erase, Chip Erase, Write Status Register,
Write Enable, Write Disable or Deep Power-Down command, CS# must be driven high exactly at a
byte boundary, otherwise the command is rejected, and is not executed. That is CS# must driven high
when the number of clock pulses after CS# being driven low is an exact multiple of eight. For Page
Program, if at any time the input byte is not a full byte, nothing will happen and WEL will not be reset.

Write Enable (WREN) (06H)
The Write Enable (WREN) command is for setting the Write Enable Latch (WEL) bit. The Write
Enable Latch (WEL) bit must be set prior to every Page Program (PP), Sector Erase (SE), Block
Erase (BE), Chip Erase (CE) and Write Status Register (WRSR) command. The Write Enable (WREN)

Read Status Register (RDSR) (05H or 35H)
The Read Status Register (RDSR) command is for reading the Status Register. The Status Register
may be read at any time, even while a Program, Erase or Write Status Register cycle is in progress.
When one of these cycles is in progress, it is recommended to check the Write In Progress (WIP) bit
before sending a new command to the device. It is also possible to read the Status Register
continuously. For command code “05H”, the SO will output Status Register bits S7~S0. The
command code “35H”, the SO will output Status Register bits S15~S8.

Write Status Register (WRSR) (01H)
The Write Status Register (WRSR) command allows new values to be written to the Status Register.
Before it can be accepted, a Write Enable (WREN) command must previously have been executed.
After the Write Enable (WREN) command has been decoded and executed, the device sets the Write
Enable Latch (WEL).
The Write Status Register (WRSR) command has no effect on S15, S1 and S0 of the Status
Register. CS# must be driven high after the eighth or sixteen bit of the data byte has been latched in.
If not, the Write Status Register (WRSR) command is not executed. If CS# is driven high after eighth
bit of the data byte, the CMP and QE and SRP1 bits will be cleared to 0. As soon as CS# is driven
high, the self-timed Write Status Register cycle (whose duration is tW) is initiated. While the Write
Status Register cycle is in progress, the Status Register may still be read to check the value of the
Write In Progress (WIP) bit. The Write In Progress (WIP) bit is 1 during the self-timed Write Status
Register cycle, and is 0 when it is completed. When the cycle is completed, the Write Enable Latch
(WEL) is reset.
The Write Status Register (WRSR) command allows the user to change the values of the Block
Protect (SEC, TB, BP2, BP1, BP0) bits, to define the size of the area that is to be treated as
read-only, as defined in Table1. The Write Status Register (WRSR) command also allows the user to
set or reset the Status Register Protect (SRP1 and SRP0) bits in accordance with the Write Protect
(WP#) signal. The Status Register Protect (SRP1 and SRP0) bits and Write Protect (WP#) signal
allow the device to be put in the Hardware Protected Mode. The Write Status Register (WRSR)
command is not executed once the Hardware Protected Mode is entered.
Figure5. Write Status Register Sequence Diagram
Read Data Bytes (READ) (03H)
The Read Data Bytes (READ) command is followed by a 3-byte address (A23-A0), each bit being
latched-in during the rising edge of SCLK. Then the memory content, at that address, is shifted out
on SO, each bit being shifted out, at a Max frequency fR, during the falling edge of SCLK. The first
byte addressed can be at any location. The address is automatically incremented to the next higher
address after each byte of data is shifted out. The whole memory can, therefore, be read with a
single Read Data Bytes (READ) command. Any Read Data Bytes (READ) command, while an Erase,
Program or Write cycle is in progress, is rejected without having any effects on the cycle that is in
progress.

The Dual I/O Fast Read command is similar to the Dual Output Fast Read command but with the
capability to input the 3-byte address (A23-0) and a “Continuous Read Mode” byte 2-bit per clock by
SI and SO, each bit being latched in during the rising edge of SCLK, then the memory contents are

Dual I/O Fast Read With “Continuous Read Mode”
The Dual I/O Fast Read command can further reduce command overhead through setting the

Read Mode” bits (M7-0) =AXH, then the next Dual I/O Fast Read command (after CS# is raised and
then lowered) does not require the BBH command code. The command sequence is shown in
followed Figure11. If the “Continuous Read Mode” bits (M7-0) are any value other than AXH, the next

Page Program (PP) (02H)
The Page Program (PP) command is for programming the memory. A Write Enable (WREN)
command must previously have been executed to set the Write Enable Latch (WEL) bit before
sending the Page Program command.
The Page Program (PP) command is entered by driving CS# Low, followed by the command code,
three address bytes and at least one data byte on SI. If the 8 least significant address bits (A7-A0) are
not all zero, all transmitted data that goes beyond the end of the current page are programmed from
the start address of the same page (from the address whose 8 least significant bits (A7-A0) are all
zero). CS# must be driven low for the entire duration of the sequence. The Page Program command
sequence: CS# goes low sending Page Program command 3-byte address on SI at least 1 byte data
on SI CS# goes high. The command sequence is shown in Figure14. If more than 256 bytes are sent
to the device, previously latched data are discarded and the last 256 data bytes are guaranteed to be
programmed correctly within the same page. If less than 256 data bytes are sent to device, they are
correctly programmed at the requested addresses without having any effects on the other bytes of the
same page. CS# must be driven high after the eighth bit of the last data byte has been latched in;
otherwise the Page Program (PP) command is not executed.
As soon as CS# is driven high, the self-timed Page Program cycle (whose duration is tPP) is initiated.
While the Page Program cycle is in progress, the Status Register may be read to check the value of
the Write In Progress (WIP) bit. The Write In Progress (WIP) bit is 1 during the self-timed Page
Program cycle, and is 0 when it is completed. At some unspecified time before the cycle is completed,

Deep Power-Down (DP) (B9H)
Executing the Deep Power-Down (DP) command is the only way to put the device in the lowest
consumption mode (the Deep Power-Down Mode). It can also be used as an extra software
protection mechanism, while the device is not in active use, since in this mode, the device ignores all
Write, Program and Erase commands. Driving CS# high deselects the device, and puts the device in
the Standby Mode (if there is no internal cycle currently in progress). But this mode is not the Deep
Power-Down Mode. The Deep Power-Down Mode can only be entered by executing the Deep
Power-Down (DP) command. Once the device has entered the Deep Power-Down Mode, all
commands are ignored except the Release from Deep Power-Down and Read Device ID (RDI)
command. This releases the device from this mode. The Release from Deep Power-Down and Read
Device ID (RDI) command also allows the Device ID of the device to be output on SO.
The Deep Power-Down Mode automatically stops at Power-Down, and the device always Power-Up
in the Standby Mode. The Deep Power-Down (DP) command is entered by driving CS# low, followed
by the command code on SI. CS# must be driven low for the entire duration of the sequence.

Release from Deep Power-Down And Read Device ID (RDI) (ABH)
The Release from Power-Down or Device ID command is a multi-purpose command. It can be used
to release the device from the Power-Down state or obtain the devices electronic identification (ID)
number.
To release the device from the Power-Down state, the command is issued by driving the CS# pin
low, shifting the instruction code “ABH” and driving CS# high as shown in Figure20. Release from
Power-Down will take the time duration of tRES1 (See AC Characteristics) before the device will
resume normal operation and other command are accepted. The CS# pin must remain high during
the tRES1 time duration.
When used only to obtain the Device ID while not in the Power-Down state, the command is
initiated by driving the CS# pin low and shifting the instruction code “ABH” followed by 3-dummy
byte. The Device ID bits are then shifted out on the falling edge of SCLK with most significant bit
(MSB) first as shown in Figure20. The Device ID value for the ACE25C320G is listed in
Manufacturer and Device Identification table. The Device ID can be read continuously. The
command is completed by driving CS# high.
When used to release the device from the Power-Down state and obtain the Device ID, the
command is the same as previously described, and shown in Figure20, except that after CS# is
driven high it must remain high for a time duration of tRES2 (See AC Characteristics). After this
time duration the device will resume normal operation and other command will be accepted. If the
Release from Power-Down / Device ID command is issued while an Erase, Program or Write cycle
is in process (when WIP equal 1) the command is ignored and will not have any effects on the
current cycle.

Read Identification (RDID) (9FH)
The Read Identification (RDID) command allows the 8-bit manufacturer identification to be read,
followed by two bytes of device identification. The device identification indicates the memory type in
the first byte, and the memory capacity of the device in the second byte. Any Read Identification
(RDID) command while an Erase or Program cycle is in progress, is not decoded, and has no effect
on the cycle that is in progress. The Read Identification (RDID) command should not be issued while
the device is in Deep Power-Down Mode.
The device is first selected by driving CS# to low. Then, the 8-bit command code for the command is
shifted in. This is followed by the 24-bit device identification, stored in the memory, being shifted out
on Serial Data Output, each bit being shifted out during the falling edge of Serial Clock. The command
sequence is shown in Figure28. The Read Identification (RDID) command is terminated by driving
CS# to high at any time during data output. When CS# is driven high, the device is put in the Standby
Mode. Once in the Standby Mode, the device waits to be selected, so that it can receive, decode and
execute commands.

Erase Security Registers (44H)
The ACE25C320G provides four 256-byte Security Registers which can be erased and
programmed individually. These registers may be used by the system manufacturers to store
security and other important information separately from the main memory array.
The Erase Security Registers command is similar to Sector/Block Erase command. A Write Enable

The Erase Security Registers command sequence: CS# goes low sending Erase Security
Registers command CS# goes high. The command sequence is shown in Figure25. CS# must be

Security Registers command is not executed. As soon as CS# is driven high, the self-timed Erase
Security Registers cycle (whose duration is tSE) is initiated. While the Erase Security Registers
cycle is in progress, the Status Register may be read to check the value of the Write In Progress

and is 0 when it is completed. At some unspecified time before the cycle is completed, the Write
Enable Latch (WEL) bit is reset. The Security Registers Lock Bit (LB) in the Status Register can be
used to OTP protect the security registers. Once the LB bit is set to 1, the Security Registers will be
permanently locked; the Erase Security Registers command will be ignored.

Write Enable for Volatile Status Register (50h)
The non-volatile Status Register bits described on page 40 can also be written to as volatile bits.
During power up reset, the non-volatile Status Register bits are copied to a volatile version of the
Status Register that is used during device operation. This gives more flexibility to change the system
configuration and memory protection schemes quickly without waiting for the typical non-volatile bit
write cycles or affecting the endurance of the Status Register non-volatile bits. To write the volatile
version of the Status Register bits, the Write Enable for Volatile Status Register (50h) command
must be issued prior to each Write Status Registers (01h) command. Write Enable for Volatile Status
Register command (Figure 29) will not set the Write Enable Latch (WEL) bit, it is only valid for the
