GENERAL DESCRIPTION
The Pm25LV010/020/040 are 1 Mbit/2 Mbit/4 Mbit 3.0 Volt-only Serial Peripheral Interface (SPI) Flash memories.
The devices are designed to support 33 MHz fastest clock rate in the industry in normal read mode, 33 MHz in fast
read mode and the bottom 4 Kbyte sector into four smaller 1 Kbyte sectors features. The devices use a single low
voltage, ranging from 2.7 Volt to 3.6 Volt, power supply to perform read, erase and program operations. The devices
can be programmed in standard EPROM programmers as well. The Pm25LV010-33 is backward compatible to their
predecessors Pm25LV010-25.
The Pm25LV010/020/040 are accessed through a 4-wire SPI Interface consists of Serial Data Input (Sl), Serial
Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. The devices support page program mode, 1 to
256 bytes data can be programmed into the memory in one program operation. The memory of Pm25LV010 is
divided into uniform 4 Kbyte sectors or uniform 32 Kbyte blocks (sector group - consists of eight adjacent sectors)
for data or code storage. The memory of Pm25LV020/040 are divided into uniform 4 Kbyte sectors or uniform 64
Kbyte blocks (sector group - consists of sixteen adjacent sectors). The devices have an innovative feature to
configure the bottom 4 Kbyte sector into four smaller 1 Kbyte sectors for eliminating additional serial EEPROM
needed for storing data. This is a further cost reduction for overall system.
The Pm25LV010/020/040 are manufactured on PMC’s advanced nonvolatile CMOS technology, pFLASH™. The
devices are offered in 8-pin SOIC and 8-contact WSON packages with operation frequency up to 33 MHz in fast read
and 33 MHz in normal read mode.

SPI MODES DESCRIPTION
Multiple Pm25LV010/020/040 devices can be serially The difference between these two modes is the clock
connected onto the SPI serial bus controlled by a SPI polarity when the SPI master is in Stand-by mode: the
Master i.e. microcontroller as shown in Figure 1. The serial clock remains at “0” (SCK = 0) for Mode 0 and the
devices support either of the two SPI modes:
Mode 0 (0, 0)
clock remains at “1” (SCK = 1) for Mode 1. 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.
Mode 3 (1, 1)

REGISTERS
The Pm25LV010/020/040 are designed to interface di-
rectly with the synchronous Serial Peripheral Interface
(SPI) of Motorola MC68HCxx series of microcontrollers
or all the SPI interface equipped system controllers.
The devices have an option to configure the 4 Kbyte
bottom sector (Sector 0) into four 1 Kbyte smaller
sectors (Sector 0_0, Sector 0_1, Sector 0_2 and
Sector 0_3). The finer granularity sector size archi-
tecture allows user to update data more efficiently.
This feature allows user to eliminate the need of
addtional serial EEPROM.
The devices have two superset features can be enabled
through the specific software instructions and Configu-
ration Register:
Refer to Table 1 for Configuration Register and Table 2
for Configuration Register Bit Definition.
1. Configurable sector size: The memory array of
Pm25LV010 is divided into uniform 4 Kbyte sectors
or uniform 32 Kbyte blocks (sector group - consists
of eight adjacent sectors). The memory array of
Pm25LV020/040 are divided into uniform 4 Kbyte sec-
tors or uniform 64 Kbyte blocks (sector group - con-
sists of sixteen adjacent sectors).

REGISTERS (CONTINUED)
CONFIGURATIONREGISTER
The BP0, BP1, BP2, and SRWD are non-volatile memory
cells that can be written by Write Status Register (WRSR)
instruction. The default value of BP0, BP1, BP2, and
SRWD bits were set as “0” at factory. Once those bits
are written as “0” or “1”, it will not be changed by devices
power-up or power-down until next WRSR instruction al-
ters its value. The Status Register can be read by Read
Status Register (RDSR) instruction for its value and sta-
tus. Refer to Table 8 for Instruction Set.
The Configuration Register is built by latchs need to be
set each time after power-up before enabling the 1 Kbyte
smaller sector size and 1 Kbyte sector write protection.
The Bit 0 - Bit 7 of Configuration Register are set as “0”s
after power-up reset. Therefore, the devices will be al-
ways set as normal mode - the bottom sector set as 4
Kbyte by default after power-up to maintain the back-
ward-compatibility.
The function of Configuration Register is described as
following:
The function of Status Register is described as following:
WIP bit: The Write In Progress (WIP) bit can be used to
detact the progress or completion of program or erase
operation. When WIP bit is “0”, the devices are ready for
write status register, program or erase operation. When
WIP bit is “1”, the devices are busy.
SCFG bit: The 1 Kbyte smaller sector mode is enabled
by writing “1” to SCFG bit, then Sector 0 is configured
as Sector 0_0, Sector 0_1, Sector 0_2 and Sector 0_3.
A Sector Erase (SECTOR_ER) instruction can be used
to erase any one of those four 1 Kbyte sectors. The
SCFG bit will be reset “0” state automatically at power
on stage. Thus, the 1 Kbyte smaller sector mode is
disabled at power on till SCFG bit was set.
WEL bit: The Write Enable Latch (WEL) bit indicates
the status of internal write enable latch. When WEL bit
is “0”, the write enable latch is disabled, all write opera-
tions include write status register, write configuration reg-
ister, page program, sector erase, block and chip erase
operations are inhibited. When WEL bit is “1”, the write
enablelatchisenabled. Thenwriteoperationsareallowed.
The WEL bit is enabled by Write Enable (WREN) instruc-
tion. All write register, program and erase instructions
must be preceded by a WREN instruction every time.
The WEL bit can be disabled by Write Disable (WRDI)
instruction or automatically return to reset state after the
completion of a write instruction.
The SCFG bit only can be enabled to “1” when BP0,
BP1&BP2 of status register were “1” state which in pro-
tection mode. On the other word, SCFG bit will be cleared
to “0” state when BPx were “0” to disable the protection
mode.
SP0_x bits: The write protection to those four 1 Kbyte
sectors can be activated by writing “1”s to the SP0_0,
SP0_1, SP0_2 and SP0_3 bits. The 1 Kbyte sector write
protection function can only be enabled when the SCFG
is also enabled.
BP2, BP1, BP0 bits: The Block Protection (BP2
(Pm25LV040 only), BP1, BP0) bits are used to define
the portion of memory area to be protected. Refer to Table
5 and Table 6 Block Write Protection Bits Setting for
Pm25LV010/020 and Pm25LV040. When one of the
combination of BP2, BP1 and BP0 bits were set as “1”,
the relevant memory area is protected. Any program or
erase operation to that area will be prohibited. Especially,
the Chip Erase (CHIP_ER) instruction is executed only if
all the Block Protection Bits are set as “0”s.
The Write Configuration Register (WRCR) instruction can
be used to write “0”s or “1”s into Configuration Register.
And the Read Configuration Register (RDCR) instruc-
tion can be used to read the setting of Configuration
Register. Refer to Table 8 for Instruction Set.
STATUS REGISTER
The Status Register contains WIP and WEL status bits
to indicate the status of the devices, the Block Protec-
tion Bits (BP0, BP1 and BP2 (Pm25LV040 only)) to
define the portion of memory blocks to be write protected,
If SCFG bit was enabled to support 1KB x4 sectores on
Sector 0, Sector 0’s protection status will respect SP0_x
in Configuration Register and ignore BPx bits status
whatever protection status.
and SRWD control bits to be set for status register write
protection. Refer to Table 3 and Table 4 for Status Reg-
ister Format and Status Register Bit Definition.

PROTECTION MODE
The Pm25LV010/020/040 have two protection modes:
hardware write protection and software write protection
to prevent any irrelevant operation under a possible noisy
environment and protect the data integrity.
SOFTWARE WRITE PROTECTION
The Pm25LV010/020/040 also provide 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 execution of the Write
Enable (WREN) instruction. If the WEL bit is not en-
abled first, the program, erase or write register in-
struction will be ignored.
HARDWARE WRITE PROTECTION
The devices provide two hardware write protection
features:
a. When input any program, erase or write status regis-
ter instruction, the number of clock pulse will be
checked whether it is a multiple of eight before the
execution of such instruction. Any incomplete instruc-
tion command sequence will be ignored.
b. The Block Protection (BP2, BP1, BP0) bits allow part
or whole memory area to be write protected.
Table 7. Hardware Write Protection on Status
Register
b. The devices feature a Write Protection (WP#) pin to
provide a hardware write protection method for BP2,
BP1,BP0 abd SRWD in the Status Register.
(1)When the WP# is pulled low (VIL), the Status
Register is write protected if the SRWD bit is enabled
(Refer to Table 7 for Hardware Write Protection on
Status Register). Hence part or whole memory area
can be write protected depends on the setting of BP2,
BP1 and BP0 bits.

BLOCK ERASE OPERATION
ERASEOPERATION
A Block Erase (BLOCK_ER) instruction erases a 32
Kbyte block for the Pm25LV010 or a 64 Kbyte block for
the Pm25LV020/040. Before the execution of
BLOCK_ER instruction, the Write Enable Latch (WEL)
must be enabled through a Write Enable (WREN) instruc-
tion. The WEL will be reset automatically after the
completion of block erase operation.
The memory array of Pm25LV010 is organized into uni-
form 4 Kbyte sectors or 32 Kbyte uniform blocks (sector
group - consists of eight adjacent sectors). The memory
array of Pm25LV020/040 are organized into uniform 4
Kbyte sectors or 64 Kbyte uniform blocks (sector group
- consists of sixteen adjacent sectors). The bottom sec-
tor (Sector 0) of the devices can be configured into four 1
Kbyte smaller sectors.
The BLOCK_ER instruction is entered, after the CE# is
pulled low to select the device and staying low during
the entire instruction sequence, by shifting in the
BLOCK_ER instruction code and three address bytes
via the SI. Erase operation will start immediately after
the CE# is pulled high, otherwise the BLOCK_ER in-
struction will not be executed. The internal control logic
automatically handles the erase voltage and timing. Re-
fer to Figure 14 for Block Erase Sequence.
Before a byte can be reprogrammed, the sector or block
which contains this byte must be erased first. In order to
erase the devices, there are three erase instructions in-
clude Sector Erase (SECTOR_ER), Block Erase
(BLOCK_ER) and Chip Erase (CHIP_ER) instructions
can be used. A sector erase operation allows to erase
any individual sector without affecting the data in others.
A block erase operation allows to erase any individual
block. And a chip erase operation allows to erase the
whole memory array of the devices. Pre-programs the
devices are not required prior to a sector erase, block
erase or chip erase operation.
CHIP ERASE OPERATION
A Chip Erase (CHIP_ER) instruction erases the whole
memory array of Pm25LV010/020/040. Before the ex-
ecution of CHIP_ER instruction, the Write Enable Latch
(WEL) must be enabled through a Write Enable (WREN)
instruction. The WEL will be reset automatically after
the completion of chip erase operation.
SECTOR ERASE OPERATION
A SECTOR_ER instruction erases a 4 Kbyte sector or a
1 Kbyte smaller sector (Sector 0_3, Sector 0_2, Sector
0_1, Sector 0_0) if the bottom Sector 0 has been config-
ured as four smaller sectors. Before the execution of
SECTOR_ER instruction, the Write Enable Latch (WEL)
must be enabled through a Write Enable (WREN) instruc-
tion. The WEL will be reset automatically after the
completion of sector erase operation.
The CHIP_ER instruction is entered, after the CE# is
pulled low to select the device and staying low during
the entire instruction sequence, by shifting in the
CHIP_ER instruction code via the SI. Erase operation
will start immediately after the CE# is pulled high, other-
wise the CHIP_ER instruction will not be executed. The
internal control logic automatically handles the erase
voltage and timing. Refer to Figure 15 for Chip Erase
Sequence.
The SECTOR_ER instruction is entered, after the CE#
is pulled low to select the device and staying low during
the entire instruction sequence, by shifting in the
SECTOR_ER instruction code and three address bytes
via the SI. Erase operation will start immediately after
the CE# is pulled high, otherwise the SECTOR_ER in-
struction will not be executed. The internal control logic
automatically handles the erase voltage and timing. Re-
fer to Figure 13 for Sector Erase Sequence.
During a erase operation, all instruction will be ignored
except the Read Status Register (RDSR) instruction.
The progress or completion of the erase opertion can be
determined by reading the WIP bit in Status Register
through a RDSR instruction. If WIP bit = “1”, the erase
operation is still in progress. If WIP bit = “0”, the erase
operation has been completed.
