The AT25080/160/320/640 provides 8192/16384/32768/65536 bits of serial electri-  
cally-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 AT25080/160/320/640 is available in space saving 8-lead PDIP, 8-  
lead JEDEC SOIC and 14-lead 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 sepa-  
rate ERASE cycle is required before WRITE.

BLOCK WRITE protection is enabled by programming the status register with one of four blocks of write protection. Sepa-  
rate 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.

0675M–SEEPR–9/03  
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 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 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”.

Functional  
Description  
The AT25080/160/320/640 is designed to interface directly with the synchronous serial periph-  
eral 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-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 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 contin-  
ued 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 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.
