Description
The AT25080A/160A/320A/640A provides 8,192/16,384/32,768/65,536 bits of
Serial Electrically-Erasable Programmable Read-only Memory (EEPROM)
organized as 1,024/2,048/4,096/8,192 words of 8 bits each. The device is
optimized for use in many automotive applications where low-power and
low-voltage operation are essential. The AT25080A/160A/320A/640A is available
in space-saving 8-lead JEDEC SOIC and TSSOP packages.
The AT25080A/160A/320A/640A 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 which 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 Opcode: After the device is selected with CS going low, the first byte will be received. This byte contains
the opcode that defines the operations to be performed.
Invalid Opcode: If an invalid opcode 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 one, all Write operations 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 zero. 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 one.

Functional 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 the below table. 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 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.

Bits 4 6 are zeroes when device is not in an internal write cycle.

Bits 0 7 are ones during an internal write cycle.
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 (¼), one-half (½), 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 the below table.
Bits BP0, BP1, and WPEN are nonvolatile cells which 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 one. Hardware write protection is disabled when either the WP pin is high or the WPEN bit is zero.
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 zero 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 opcode is transmitted via the SI
line followed by the byte address to be read (A15 A0, see Table 6-6). 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 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 separate instructions must
be executed. First, the device must be write enabled via the WREN instruction. Then a Write instruction may
be executed. Also, the address of the 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
opcode is transmitted via the SI line followed by the byte address (A15 A0) and the data (D7 – D0) to be
programmed (See Table 6-6). 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 = one, the write cycle is still in progress. If Bit 0 = zero, 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 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 reinitiate the serial
communication.
