are essential. The AT25080/160/320/640 is available in
space saving 8-pin PDIP, JEDEC SOIC, and 14-pin and
20-pin TSSOP packages.
The AT25080/160/320/640 is enabled through the Chip
Select pin (CS) and accessed via a 3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO),
and Serial Clock (SCK). All programming cycles are completely self-timed, and no separate ERASE cycle is
required before WRITE.
BLOCK WRITE protection is enabled by programming the
status register with one of four blocks of write protection.
Separate program enable and program disable instructions
are provided for additional data protection. Hardware data
protection is provided via the WP pin to protect against
inadvertent write attempts to the status register. The HOLD
pin may be used to suspend any serial communication
without resetting the serial sequence.

Serial Interface Description
MASTER: The device that generates the serial clock.
SLAVE: Because the Serial Clock pin (SCK) is always an
input, the AT25080/160/320/640 always operates as a
slave.
TRANSMITTER/RECEIVER: The AT25080/160/320/640
has separate pins designated for data transmission (SO)
and reception (SI).
MSB: The Most Significant Bit (MSB) is the first bit transmitted and received.
SERIAL OP-CODE: After the device is selected with CS
going low, the first byte will be received. This byte contains
the op-code that defines the operations to be performed.
INVALID OP-CODE: If an invalid op-code is received, no
data will be shifted into the AT25080/160/320/640, and the
serial output pin (SO) will remain in a high impedance state
until the falling edge of CS is detected again. This will reinitialize the serial communication.
CHIP SELECT: The AT25080/160/320/640 is selected
when the CS pin is low. When the device is not selected,
data will not be accepted via the SI pin, and the serial output pin (SO) will remain in a high impedance state.
HOLD: The HOLD pin is used in conjunction with the CS
pin to select the AT25080/160/320/640. When the device is
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, the
HOLD pin must be brought low while the SCK pin is low. To
resume serial communication, the HOLD pin is brought
high while the SCK pin is low (SCK may still toggle during
HOLD). Inputs to the SI pin will be ignored while the SO pin
is in the high impedance state.
WRITE PROTECT: The write protect pin (WP) will allow
normal read/write operations when held high. When the
WP pin is brought low and WPEN bit is “1”, all write opera-
6
AT25080/160/320/640
tions to the status register are inhibited. WP going low
while CS is still low will interrupt a write to the status register. If the internal write cycle has already been initiated, WP
going low will have no effect on any write operation to the
status register. The WP pin function is blocked when the
WPEN bit in the status register is "0". This will allow the
user to install the AT25080/160/320/640 in a system with
the WP pin tied to ground and still be able to write to the
status register. All WP pin functions are enabled when the
WPEN bit is set to “1”.
SPI Serial Interface

Functional Description
Table 3. Read Status Register Bit Definition
The AT25080/160/320/640 is designed to interface directly
with the synchronous serial peripheral interface (SPI) of the
6805 and 68HC11 series of microcontrollers.
The AT25080/160/320/640 utilizes an 8 bit instruction register. The list of instructions and their operation codes are
contained in Table 1. All instructions, addresses, and data
are transferred with the MSB first and start with a high-tolow CS transition.
Table 1. Instruction Set for the AT25080/160/320/640
Bit
Definition
Bit 0 (RDY)
Bit 0 = 0 (RDY) indicates the device is READY. Bit
0 = 1 indicates the write cycle is in progress.
Bit 1 (WEN)
Bit 1= 0 indicates the device is not WRITE
ENABLED. Bit 1 = 1 indicates the device is WRITE
ENABLED.
Bit 2 (BP0)
See Table 3.
Bit 3 (BP1)
See Table 3.
Bits 4-6 are 0s when device is not in an internal write cycle.

WRITE ENABLE (WREN): The device will power up in the
write disable state when VCC is applied. All programming
instructions must therefore be preceded by a Write Enable
instruction.
WRITE DISABLE (WRDI): To protect the device against
inadvertent writes, the Write Disable instruction disables all
programming modes. The WRDI instruction is independent
of the status of the WP pin.
READ STATUS REGISTER (RDSR): The Read Status
Register instruction provides access to the status register.
The READY/BUSY and Write Enable status of the device
can be determined by the RDSR instruction. Similarly, the
Block Write Protection bits indicate the extent of protection
employed. These bits are set by using the WRSR instruction.
See Table 4.
WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select one of four levels of protection. The AT25080/160/320/640 is divided into four array
segments. One quarter (1/4), one half (1/2), or all of the
memory segments can be protected. Any of the data within
any selected segment will therefore be READ only. The
block write protection levels and corresponding status register control bits are shown in Table 4.
The three bits, BP0, BP1, and WPEN are nonvolatile cells
that have the same properties and functions as the regular
memory cells (e.g. WREN, tWC, RDSR).

The WRSR instruction also allows the user to enable or
disable the write protect (WP) pin through the use of the
Write Protect Enable (WPEN) bit. Hardware write protection is enabled when the 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 device is
hardware write protected, writes to the Status Register,
including the Block Protect bits and the WPEN bit, and the
block-protected sections in the memory array are disabled.

Writes are only allowed to sections of the memory which
are not block-protected.
NOTE: When the WPEN bit is hardware write protected, it
cannot be changed back to “0”, as long as the WP pin is
held low.

READ SEQUENCE (READ): Reading the
AT25080/160/320/640 via the SO (Serial Output) pin
requires the following sequence. After the CS line is pulled
low to select a device, the READ op-code is transmitted via
the SI line followed by the byte address to be read (A15-A0,
Refer to Table 6). Upon completion, any data on the SI line
will be ignored. The data (D7-D0) at the specified address
is then shifted out onto the SO line. If only one byte is to be
read, the CS line should be driven high after the data
comes out. The READ sequence can be continued since
the byte address is automatically incremented and data will
continue to be shifted out. When the highest address is
reached, the address counter will roll over to the lowest
address allowing the entire memory to be read in one continuous READ cycle.
WRITE SEQUENCE (WRITE): In order to program the
AT25080/160/320/640, two separate instructions must be
executed. First, the device must be write enabled via the
Write Enable (WREN) Instruction. Then a Write (WRITE)
Instruction may be executed. Also, the address of the
8
AT25080/160/320/640
memory location(s) to be programmed must be outside the
protected address field location selected by the Block Write
Protection Level. During an internal write cycle, all commands will be ignored except the RDSR instruction.
A Write Instruction requires the following sequence. After
the CS line is pulled low to select the device, the WRITE
op-code is transmitted via the SI line followed by the byte
address (A15-A0) and the data (D7-D0) to be programmed
(Refer to Table 6). Programming will start after the CS pin
is brought high. (The LOW to High transition of the CS pin
must occur during the SCK low time immediately after
clocking in the D0 (LSB) data bit.
The READY/BUSY status of the device can be determined
by initiating a READ STATUS REGISTER (RDSR) Instruction. If Bit 0 = 1, the WRITE cycle is still in progress. If Bit 0
= 0, the WRITE cycle has ended. Only the READ STATUS
REGISTER instruction is enabled during the WRITE programming cycle.
The AT25080/160/320/640 is capable of a 32-byte PAGE
WRITE operation. After each byte of data is received, the
five low order address bits are internally incremented by
one; the high order bits of the address will remain constant.
If more than 32-bytes of data are transmitted, the address
counter will roll over and the previously written data will be
overwritten. The AT25080/160/320/640 is automatically
returned to the write disable state at the completion of a
WRITE cycle.
NOTE: If the device is not Write enabled (WREN), the
device will ignore the Write instruction and will return to the
standby state, when CS is brought high. A new CS falling
edge is required to re-initiate the serial communication.
