The AT25080A/160A/320A/640A provides 8192/16384/32768/65536 bits of serial
electrically-erasable programmable read-only memory (EEPROM) organized as
1024/2048/4096/8192 words of 8 bits each. The device is optimized for use in many
industrial and commercial applications where low-power and low-voltage operation
are essential. The AT25080A/160A/320A/640A is available in space-saving 8-lead
PDIP, 8-lead JEDEC SOIC, 8-lead MAP, and 8-lead TSSOP packages.

The AT25080A/160A/320A/640A is enabled through the Chip Select pin (CS) and
accessed via a three-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 sus-
pend 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
AT25080A/160A/320A/640A always operates as a slave.
TRANSMITTER/RECEIVER: The AT25080A/160A/320A/640A 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
AT25080A/160A/320A/640A, 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 AT25080A/160A/320A/640A 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
AT25080A/160A/320A/640A. 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 operations to the sta-
tus 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
AT25080A/160A/320A/640A 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”.

Description
The AT25080A/160A/320A/640A is designed to interface directly with the synchronous serial
peripheral interface (SPI) of the 6805 and 68HC11 series of microcontrollers.
The AT25080A/160A/320A/640A utilizes an 8-bit instruction register. The list of instructions
and their operation codes are contained in Table 5. All instructions, addresses, and data are
transferred with the MSB first and start with a high-to-low CS transition.

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 sta-
tus 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 deter-
mined 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.

WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select one of
four levels of protection. The AT25080A/160A/320A/640A is divided into four array segments.
One-quarter, one-half, 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 corre-
sponding status register control bits are shown in Table 8.
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 that 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 AT25080A/160A/320A/640A via the Serial Output
(SO) 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,
see Table 10). 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 AT25080A/160A/320A/640A, two sep-
arate instructions must be executed. First, the device must be write enabled via the WREN
instruction. Then a write (WRITE) instruction may be executed. Also, the address of the mem-
ory 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 (see Table 10). 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 RDSR instruction is enabled during the write programming cycle.
The AT25080A/160A/320A/640A 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
AT25080A/160A/320A/640A is automatically returned to the write disable state at the comple-
tion 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 reinitiate the serial communication.
