GENERAL DESCRIPTION
The IS25LD512/010/020 are 512Kbit/ 1Mbit / 2Mbit Serial Peripheral Interface (SPI) Flash memories, providing
single- or dual-output. The devices are designed to support a 33 MHz clock rate in normal read mode, and 100
MHz in fast read, the fastest in the industry. The devices use a single low voltage power supply, wide operating
voltage ranging from 2.3 Volt to 3.6 Volt, to perform read, erase and program operations. The devices can be
programmed in standard EPROM programmers.
The IS25LD512/010/020 are accessed through a 4-wire SPI Interface consisting of Serial Data Input/Output
(SlO), Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. They comply with all
recognized command codes and operations. The dual-output fast read operation provides and effective serial
data rate of 200MHz.
The devices support page program mode, where 1 to 256 bytes data can be programmed into the memory in
one program operation. These devices are divided into uniform 4 KByte sectors or uniform 32 KByte
blocks.(IS25LD020 is uniform 4 KByte sectors or uniform 64 KByte).
The IS25LD512/010/020 are manufactured on pFLASH™’s advanced non-volatile technology. The devices are
offered in 8-pin SOIC 150mil, 8-contact WSON, 8-pin VVSOP, 8-pin USON and 8-pin TSSOP. The devices
operate at wide temperatures between -40°C to +105°C.

SPI MODES DESCRIPTION
Multiple IS25LD512/010/020 devices can be connected The difference between these two modes is the clock
on the SPI serial bus and controlled by a SPI Master, polarity when the SPI master is in Stand-by mode: the
i.e. microcontroller, as shown in Figure 1. The devices serial clock remains at “0” (SCK = 0) for Mode 0 and
support either of two SPI modes:
Mode 0 (0, 0)
the clock remains at “1” (SCK = 1) for Mode 3. Please
refer to Figure 2. For both modes, the input data is
latched on the rising edge of Serial Clock (SCK), and
the output data is available from the falling edge of
SCK.

PROTECTION MODE
The IS25LD512/010/020 have two types of write-
protection mechanisms: hardware and software.
These are used to prevent irrelevant operation in a

HARDWARE WRITE-PROTECTION
The devices provide two hardware write-protection
features:
Writable
a. When inputting a program, erase or write status
register instruction, the number of clock pulse is
checked to determine whether it is a multiple of eight
before the executing. Any incomplete instruction
command sequence will be ignored.
b. The Write Protection (WP#) pin provides a
hardware write protection method for BP2, BP1, BP0
and SRWD in the Status Register. Refer to the
STATUS REGISTER description.
c. Write inhibit is 1.8V, all write sequence will be
ignored when Vcc drop to 1.8V and lower
SOFTWARE WRITE PROTECTION
The IS25LD512/010/020 also provides two software
write protection features:
a. Before the execution of any program, erase or write
status register instruction, the Write Enable Latch
(WEL) bit must be enabled by executing a Write
Enable (WREN) instruction. If the WEL bit is not
enabled first, the program, erase or write register
instruction will be ignored.
b. The Block Protection (BP2, BP1, BP0) bits allow part
or the whole memory area to be write-protected.

HOLD OPERATION
HOLD# is used in conjunction with CE# to select
the IS25LD512/010/020. When the devices are
selected and a serial sequence is underway,
HOLD# can be used to pause the serial
communication with the master device without
resetting the serial sequence. To pause, HOLD# is
brought low while the SCK signal is low. To resume
serial communication, HOLD# is brought high while
the SCK signal is low (SCK may still toggle during
HOLD). Inputs to SlO will be ignored while SO is in
the high impedance state.

The PAGE_PROG instruction code, three address

operation can be determined by reading the WIP bit in
the Status Register using a RDSR instruction. If the
WIP bit is “1”, the erase operation is still in progress. If
the WIP bit is “0”, the erase operation has been
completed.
The memory array of the IS25LD512/010 is organized
into uniform 4 KByte sectors or 32 KByte uniform
blocks (a block consists of eight adjacent sectors).
IS25LD020 is organized into uniform 4 KByte sectors
or 64 KByte uniform blocks (a block consists of sixteen
adjacent sectors)
BLOCK_ER COMMAND (BLOCK ERASE)
OPERATION
Before a byte can be reprogrammed, the sector or
block that contains the byte must be erased (erasing
sets bits to “1”). In order to erase the devices, there are
three erase instructions available: Sector Erase
(SECTOR_ER), Block Erase (BLOCK_ER) and Chip
Erase (CHIP_ER). A sector erase operation allows any
individual sector to be erased without affecting the data
in other sectors. A block erase operation erases any
individual block. A chip erase operation erases the
whole memory array of a device. A sector erase, block
erase or chip erase operation can be executed prior to
any programming operation.
A Block Erase (BLOCK_ER) instruction erases a 64
KByte block of the IS25LD020, and 32 KByte block of
the IS25LD512C/010C. Before the execution of a
BLOCK_ER instruction, the Write Enable Latch (WEL)
must be set via a Write Enable (WREN) instruction.
The WEL is reset automatically after the completion of
a block erase operation.
The BLOCK_ER instruction code and three address
bytes are input via SI. Erase operation will start
immediately after the CE# is pulled high, otherwise the
BLOCK_ER instruction will not be executed. The
internal control logic automatically handles the erase
voltage and timing. Refer to Figure 15 for Block Erase
Sequence.
SECTOR_ER COMMAND (SECTOR ERASE)
OPERATION
A SECTOR_ER instruction erases a 4 KByte sector
Before the execution of a SECTOR_ER instruction, the
Write Enable Latch (WEL) must be set via a Write
Enable (WREN) instruction. The WEL bit is reset
automatically after the completion of sector an erase
operation.
CHIP_ER COMMAND (CHIP ERASE) OPERATION
A Chip Erase (CHIP_ER) instruction erases the entire
memory array of a IS25LD512/010/020. Before the
execution of CHIP_ER instruction, the Write Enable
Latch (WEL) must be set via a Write Enable (WREN)
instruction. The WEL is reset automatically after
completion of a chip erase operation.
A SECTOR_ER instruction is entered, after CE# is
pulled low to select the device and stays low during the
entire instruction sequence The SECTOR_ER
instruction code, and three address bytes are input via
SI. Erase operation will start immediately after CE# is
pulled high. The internal control logic automatically
handles the erase voltage and timing. Refer to Figure
14 for Sector Erase Sequence.
The CHIP_ER instruction code is input via the SI.
Erase operation will start immediately after CE# is
pulled high, otherwise the CHIP_ER instruction will not
be executed. The internal control logic automatically
handles the erase voltage and timing. Refer to Figure
16 for Chip Erase Sequence.
During an erase operation, all instruction will be
ignored except the Read Status Register (RDSR)

Read Safe Guard register
The READ Safe Guard instruction code is transmitted via the SlO line, followed by three address bytes (A23 - A0) of
the first register location to be read. The first byte data (D7 - D0) addressed is then shifted out on the SO line, MSb
first. The address is automatically incremented after each byte of data is shifted out. The read operation can be
terminated at any time by driving CE# high (VIH) after the data comes out.

SEC_UNLOCK COMMAND OPERATION
The Sector unlock command allows the user to
select a specific sector to allow program and erase
operations. This instruction is effective when the
blocks are designated as write-protected through
the BP0, BP1 and BP2 bits in the status register.
Only one sector can be enabled at any time. To
enable a different sector, a previously enabled
sector must be disabled by executing a Sector Lock
command. The instruction code is followed by a
24-bit address specifying the target sector, but A0
through A11 are not decoded. The remaining
sectors within the same block remain in read-only
mode.

In the sector unlock procedure, [A11:A0] needs equal to “0”, unlock procedure is
completed, otherwise chip will regard it as illegal command.
Note: 1.If the clock number will not match 8 clocks(command)+ 24 clocks (address), it will be ignored.
2.It must be executed write enable (06h) before sector unlock instructions.

SECT_LOCK COMMAND OPERATION
The Sector Lock command reverses the function of
the Sector Unlock command. The instruction code
does not require an address to be specified, as only
one sector can be enabled at a time. The remaining
sectors within the same block remain in read-only
mode.
