AT25080B
AT25160B
The AT25080B/160B provides 8192/16384 bits of serial electrically-erasable programmable read-only memory (EEPROM) organized as 1024/2048 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 AT25080B/160B is available
in space-saving 8-lead JEDEC SOIC, 8-lead UDFN, 8-lead TSSOP, 8-lead XDFN,
and 8-ball VFBGA packages.
The AT25080B/160B 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 suspend any serial communication without resetting the serial sequence.

Serial Interface Description
1M
Write Cycles
MASTER: The device that generates the serial clock.
SLAVE: Because the Serial Clock pin (SCK) is always an input, the AT25080B/160B always operates as a slave.
TRANSMITTER/RECEIVER: The AT25080B/160B 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 AT25080B/160B, 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 AT25080B/160B 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 AT25080B/160B. 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 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 AT25080B/160B 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”.

Functional Description
The AT25080B/160B is designed to interface directly with the synchronous serial peripheral interface (SPI) of the
6805 and 68HC11 series of microcontrollers.
The AT25080B/160B utilizes an 8-bit instruction register. The list of instructions and their operation codes are contained in Table 3-1. All instructions, addresses, and data are transferred with the MSB first and start with a high-tolow 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.

Bit 0 = “0” (RDY) indicates the device is READY. Bit 0 = “1” indicates the write cycle

Bits 0–7 are “1”s during an internal write cycle.

5228D–SEEPR–4/10
WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select one of four levels of protection. The AT25080B/160B 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 corresponding status register control bits are shown in Table 3-4.
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 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 AT25080B/160B 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 3-6). 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.

5228D–SEEPR–4/10
AT25080B/160B
WRITE SEQUENCE (WRITE): In order to program the AT25080B/160B, two separate 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 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 (see Table 3-6). 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
RDSR instruction is enabled during the write programming cycle.
The AT25080B/160B is capable of a 32-byte page write operation. After each byte of data is received, the five loworder 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 AT25080B/160B 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.
