PIN DESCRIPTIONS
Serial Output (SO)
Hold (HOLD)
HOLD isusedinconjunctionwiththeCSpintoselectthe
device. Once the part is selected and a serial sequence
is underway, HOLD may be used to pause the serial
communication with the controller without resetting the
serial sequence. To pause, HOLD must be brought
LOW while SCK is LOW. To resume communication,
HOLD is brought HIGH, again while SCK is LOW. If the
pause feature is not used, HOLD should be held HIGH
at all times.
SO is a push/pull serial data output pin. During a read
cycle, data is shifted out on this pin. Data is clocked out
by the falling edge of the serial clock.
Serial Input (SI)
SI is the serial data input pin. All opcodes, byte
addresses, and data to be written to the memory are
input on this pin. Data is latched by the rising edge of the
serial clock.
PIN CONFIGURATION
Serial Clock (SCK)
The Serial Clock controls the serial bus timing for data
input and output. Opcodes, addresses, or data present
on the SI pin are latched on the rising edge of the clock
input, while data on the SO pin change after the falling
edge of the clock input.

standby power mode. CS LOW enables the X25160,
placing it in the active power mode. It should be noted
that after power-up, a HIGH to LOW transition on CS is
required prior to the start of any operation.

When WP is LOW and the nonvolatile bit WPEN is “1”,
nonvolatile writes to the X25160 status register are
disabled, but the part otherwise functions normally.
WhenWP isheldHIGH, allfunctions, includingnonvola-
tile writes operate normally. WP going LOW while CS is
still LOW will interrupt a write to the X25160 status
register. If the internal write cycle has already been
initiated, WP going LOW will have no effect on a write.

PRINCIPLES OF OPERATION
Status Register
The X25160 is a 2K x 8 E2PROM designed to interface
directly with the synchronous serial peripheral interface
(SPI) of many popular microcontroller families.
The RDSR instruction provides access to the status
register. The status register may be read at any time,
even during a write cycle. The status register is format-
ted as follows:
The X25160 contains an 8-bit instruction register. It is
accessed via the SI input, with data being clocked in on
therisingSCK. CS mustbeLOWandtheHOLD andWP
inputs must be HIGH during the entire operation. The
WP input is “Don’t Care” if WPEN is set “0”.

BP0 WEL WIP
3064 PGM T02
WPEN, BP0 and BP1 are set by the WRSR instruction.
WEL and WIP are read-only and automatically set by
other operations.
Table 1 contains a list of the instructions and their
opcodes. All instructions, addresses and data are trans-
ferred MSB first.
The Write-In-Process (WIP) bit indicates whether the
X25160 is busy with a write operation. When set to a “1”,
a write is in progress, when set to a “0”, no write is in
progress. During a write, all other bits are set to “1”.
DatainputissampledonthefirstrisingedgeofSCKafter
CS goes LOW. SCK is static, allowing the user to stop
the clock and then resume operations. If the clock line is
shared with other peripheral devices on the SPI bus, the
usercanasserttheHOLD inputtoplacetheX25160into
a“PAUSE”condition.AfterreleasingHOLD,theX25160
will resume operation from the point when HOLD was
first asserted.
The Write Enable Latch (WEL) bit indicates the status of
the“writeenable”latch.Whensettoa“1”,thelatchisset,
when set to a “0”, the latch is reset.
The Block Protect (BP0 and BP1) bits are nonvolatile
and allow the user to select one of four levels of protec-
tion. The X25160 is divided into four 4096-bit segments.
One, two, or all four of the segments may be protected.
That is, the user may read the segments but will be
unabletoalter(write)datawithintheselectedsegments.
The partitioning is controlled as illustrated below.
Write Enable Latch
The X25160 contains a “write enable” latch. This latch
must be SET before a write operation will be completed
internally. The WREN instruction will set the latch and
the WRDI instruction will reset the latch. This latch is
automatically reset upon a power-up condition and after
the completion of a byte, page, or status register write
cycle.

Prior to any attempt to write data into the X25160, the
“write enable” latch must first be set by issuing the
WRENinstruction(SeeFigure3). CS isfirsttakenLOW,
then the WREN instruction is clocked into the X25160.
After all eight bits of the instruction are transmitted, CS
must then be taken HIGH. If the user continues the write
operation without taking CS HIGH after issuing the
WREN instruction, the write operation will be ignored.

The Write Protect (WP) pin and the nonvolatile Write
ProtectEnable(WPEN)bitintheStatusRegistercontrol
theprogrammablehardwarewriteprotectfeature.Hard-
ware write protection is enabled when WP pin is LOW,
and the WPEN bit is “1”. Hardware write protection is
disabled when either the WP pin is HIGH or the WPEN
bit is “0”. When the chip is hardware write protected,
nonvolatile writes are disabled to the Status Register,
including the Block Protect bits and the WPEN bit itself,
as well as the block-protected sections in the memory
array. Onlythesectionsofthememoryarraythatarenot
block-protected can be written.
To write data to the E2PROM memory array, the user
issues the WRITE instruction, followed by the address
and then the data to be written. This is minimally a
thirty-two clock operation. CS must go LOW and remain
LOW for the duration of the operation. The host may
continue to write up to 32 bytes of data to the X25160.
The only restriction is the 32 bytes must reside on the
same page. If the address counter reaches the end of
the page and the clock continues, the counter will “roll
over” to the first address of the page and overwrite any
data that may have been written.
Note: Since the WPEN bit is write protected, it
cannot be changed back to a “0”, as long as
the WP pin is held LOW.
For the write operation (byte or page write) to be
completed, CS can only be brought HIGH after bit 0 of
databyteNisclockedin.IfitisbroughtHIGHatanyother
time the write operation will not be completed. Refer to
Figures 4 and 5 below for a detailed illustration of the
write sequences and time frames in which CS going
HIGH are valid.
Clock and Data Timing
Data input on the SI line is latched on the rising edge of
SCK. Data is output on the SO line by the falling edge of
SCK.
Read Sequence
To write to the status register, the WRSR instruction is
followed by the data to be written. Data bits 0, 1, 4, 5 and
6 must be “0”. This sequence is shown in Figure 6.
When reading from the E2PROM memory array, CS is
first pulled LOW to select the device. The 8-bit READ
instruction is transmitted to the X25160, followed by the
16-bit address of which the last 11 are used. After the
READ opcode and address are sent, the data stored in
the memory at the selected address is shifted out on the
SO line. The data stored in memory at the next address
can be read sequentially by continuing to provide clock
pulses. The address is automatically incremented to the
nexthigheraddressaftereachbyteofdataisshiftedout.
When the highest address is reached ($07FF) the
address counter rolls over to address $0000 allowing
the read cycle to be continued indefinitely. The read
operation is terminated by taking CS HIGH. Refer to the
read E2PROM array operation sequence illustrated in
Figure 1.
While the write is in progress following a status register or
E2PROMwritesequence,thestatusregistermaybereadto
check the WIP bit. During this time the WIP bit will be HIGH.
Hold Operation
The HOLD input should be HIGH (at VIH) under normal
operation. If a data transfer is to be interrupted HOLD
canbepulledLOWtosuspendthetransferuntilitcanbe
resumed. The only restriction is the SCK input must be
LOWwhenHOLDisfirstpulledLOWandSCKmustalso
be LOW when HOLD is released.
The HOLD input may be tied HIGH either directly to VCC
or tied to VCC through a resistor.

Operational Notes
Data Protection
The X25160 powers-up in the following state:
• The device is in the low power standby state.
The following circuitry has been included to prevent
inadvertent writes:
• The “write enable” latch is reset upon power-up.
• A HIGH to LOW transition on CS is required to
enter an active state and receive an instruction.
• A WREN instruction must be issued to set the “write
enable” latch.
• SO pin is high impedance.
• CS must come HIGH at the proper clock count in
order to start a write cycle.
• The “write enable” latch is reset.
