SerialOutput (Q). Theoutput pinis used totrans-
fer data serially out of the Memory. Data is shifted
out on the falling edge of the serial clock.
Serial Input (D). The input pin is used to transfer
dataseriallyinto thedevice.Itreceivesinstructions,
addresses, and the data to be written. Input is
latched on the rising edge of the serial clock.
The device connectedto the bus is selectedwhen
thechip selectinput(S) goeslow. Communications
with the chip can be interrupted with a hold input
(HOLD). The write operation is disabled by a write
protect input (W).
Data is clocked in during the low to high transition
of clock C, data is clocked out during the high to
low transitionof clock C.

Write Protect (W).
This pin is for hardware write
protection. When W is low, writes to the Memory
aredisabledbutanyotheroperationsstayenabled.
When Wis high,all writes operationsare available.

thedata streamwill resetthewrite enablelatchand
prevent programming. No action on W or on the
write enable latch can interrupt a write cycle which
has commenced.
Chip Select (S).
When S is high, the Memory is
deselected and the Q output pin is at high imped-
ance and, unless an internal write operation is
underwaythe Memorywill be in the standby power
mode. S low enables the Memory, placing it in the
active power mode. It should be noted that after

Hold (HOLD).
The HOLD pin is used to pause
operation. If an invalid instruction is sent (one not
contained in Table 3), the chip is automatically
deselected. For operations that read or write data
in the memory array, bit 3 of the instruction is the
MSB of the address, otherwise, it is a don’t care.
serial communications with the Memory without
resetting the serial sequence. To take the Hold
condition into account, the product must be se-
lected (S = 0). Then the Hold state is validated by
a high tolow transitionon HOLDwhen C islow. To
resumethecommunications,HOLDis broughthigh
while C is low. During the Hold conditionD, Q, and
C are at a high impedance state.
Write Enable (WREN) and Write Disable (WRDI)
The Memory contains a write enable latch. This
latch must be set prior to every WRITE or WRSR
operation. The WREN instructionwill set the latch
and the WRDI instruction will reset the latch. The
latch is reset under the following conditions:
When the Memoryis underthe Hold condition,it is
possibletodeselectthedevice.However,the serial
communications will remain paused after a rese-
lect, and the chip will be reset.
– W pin is low
– Power on
TheMemorycan bedrivenbyamicrocontrollerwith
its SPI peripheral running in either of the two fol-
lowingmodes:(CPOL, CPHA) = (’0’, ’0’)or (CPOL,
CPHA) = (’1’, ’1’).
– WRDI instruction executed
– WRSR instruction executed
– WRITEinstruction executed
Forthesetwo modes,inputdatais latchedinby the
low to high transitionof clockC, and output data is
available from the high to low transition of Clock
(C).
As soon as the WREN or WRDI instruction is
received by the memory, the circuit executes the
instruction and enters a wait mode until it is dese-
lected.
Thedifferencebetween(CPOL, CPHA)= (0,0)and
(CPOL, CPHA) = (1, 1) is the stand-by polarity: C
remains at ’0’ for (CPOL, CPHA) = (0, 0) and C
remainsat ’1’for(CPOL,CPHA)=(1,1)whenthere
is no data transfer.
Read Status Register (RDSR)
TheRDSRinstructionprovidesaccesstothestatus
register. The status register may be read at any
time, even during a writeto the memory operation.
If a Read Status register reaches the 8th bit of the
Status register, an additional 9th clock pulse will
wrap around to read the 1st bit of the Status Reg-
ister
OPERATIONS
All instructions, addresses and data are shifted in
and out of the chip MSB first. Data input (D) is
sampled on the first rising edge of clock (C) after
thechip select (S) goes low. Prior to any operation,
a one-byte instruction code must be enteredin the
chip. This code is entered via the data input (D),
and latched on the rising edge of the clock input
(C). To enter an instructioncode, the productmust
have been previously selected (S = low). Table 3
shows the instruction set and format for device

During a write to the memory operation to the
memory array, all bits BP1, BP0, WEL, WIP are
valid and can be read. During a write to the status
register, only the bits WEL and WIP are valid and
can be read. The values of BP1 and BP0 read at
thattimecorrespondto thepreviouscontentsof the
status register.
When set to a ’1’a writeis in progress,when set to
a ’0’ no write is in progress.
The Write Enable Latch (WEL) read-only bit indi-
catesthe statusofthe writeenable latch. When set
to a ’1’ the latch is set, when set to a ’0’ the latch is
reset. The Block Protect (BP0 and BP1) bits indi-
cate the extent of the protectionemployed. These
bits are set by the user issuing the WRSR instruc-
tion. These bits are non-volatile.
TheWrite-In-Process (WIP) read-onlybit indicates
whetherthe Memory is busywith a writeoperation.

of the read instruction contains address bit A8
(mostsignificantaddressbit). Thenthe datastored
inthememory attheselectedaddressis shiftedout
on the Q output pin; each bit being shifted out
during the falling edge of the clock (C). The data
stored in the memory at the next address can be
read in sequence by continuing to provide clock
pulses. The byte address is automatically incre-
mented to the next higher address after each byte
of data is shiftedout. When the highestaddress is
reached,theaddresscounterrollsover to0h allow-
ing the read cycle to be continuedindefinitely.The
read operation is terminated by deselecting the
chip.Thechipcanbe deselectedat anytime during

will be rejected and will deselect the chip.
TheWRSR instructionallowsthe usertoselect the
size of protected memory. The user may read the
blocks but will be unable to write within the pro-
tected blocks. The blocks and respective WRSR
control bits are shown in Table 4.
When the WRSR instruction and the 8 bits of the
Status Register are latched-in, the internal write
cycle is then triggered by the rising edge of S.
Thisrising edge of S must appearno laterthan the
16th clock cycle of the WRSR instruction of the

clock pulse before the rising edge of S), otherwise
the internal write sequence is not performed.

Byte Write Operation
must reside on the same page. The page write
mode is the same as the byte write mode except
that instead of deselectingthe device after the first
byteofdata, upto15additionalbytescanbeshifted
in prior to deselecting the chip. A page address
beginswith addressxxxx 0000 and ends with xxxx
1111.If the addresscounterreaches xxxx 1111and
the clock continues, the counter will roll over to the
firstaddress of the page(xxxx0000) and overwrite
any previously written data. The programming cy-
cle will only start if the S transition occurs just after
the eighth bit of data of a word is received.
Prior to any write attempt, the write enable latch
must be set by issuing the WREN instruction. First
the device is selected(S = low)and a serial WREN
instruction byte is issued. Then the product is de-
selectedby taking S high. After the WREN instruc-
tion byte is sent, the Memory will set the write
enable latch and then remain in standby until it is
deselected. Then the write state is entered by
selecting the chip, issuing two bytes of instruction
and address, and one byte of data.
Chip Select (S) must remain low for the entire
duration of the operation. The product must be
deselectedjust afterthe eighthbitof datahasbeen
latchedin. If not,the write process is cancelled.As
soon as the product is deselected, the self-timed
writecycleisinitiated. Whilethewrite isin progress,
thestatusregistermay be readto checkBP1,BP0,
WEL and WIP. WIP is high during the self-timed
write cycle. When the cycle is completed,the write
enable latch is reset.
POWER ON STATE
After a Power up the Memory is in the following
state:
– The device is in the low power standby state.
– The chip is deselected.
– The chip is not in hold condition.
– The write enable latch is reset.
Page Write Operation
– BP1 and BP0 are unchanged (non-volatile
bits).
A maximum of 16 bytes of data may be written
during one non-volatile write cycle. All 16 bytes

DATA PROTECTION AND PROTOCOL SAFETY
– All inputs are protectedagainstnoise, see Table
6.
– Afterany of theoperationsWREN,WRDI,RDSR
is completed, the chip enters a wait state and
waits for a deselect.
– The write enable latch is reset upon power-up.
– Thewriteenablelatchis resetwhenWis brought
low.
– Non valid S and HOLD transitionsare not taken
into account.
– S must come high at the proper clock count in
order to start a non-volatile write cycle (in the
memory array or in the status register), that is
theChipSelectSmustriseduringtheclockpulse
following the introduction of a multiple of 8 bits.
– Access to the memory array during non-volatile
programmingcycleis ignored;however,the pro-
gramming cycle continues.
INITIAL DELIVERY STATE
Thedevice is delivered with the memory array in a
fully erased state (all data set at all ”1’s” or FFh).
The block protect bits are initialized to 00.
