Description  
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  
automotive 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 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 suspend any serial communication without resetting the  
serial sequence.

5082B–SEEPR–1/05  
AT25080A/160A/320A/640A  
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 des-  
ignated 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 imped-  
ance 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 opera-  
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 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”.

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 instruc-  
tions 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 indepen-  
dent 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.

5082B–SEEPR–1/05  
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 corresponding status register control bits are shown in Table 8.  
Bits BP0, BP1, and WPEN are nonvolatile cells that have the same properties and func-  
tions 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 hard-  
ware 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.

5082B–SEEPR–1/05  
AT25080A/160A/320A/640A  
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 (A15A0, see Table 10). Upon completion, any data on the SI line will be  
ignored. The data (D7D0) 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 incre-  
mented 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 (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 (A15A0) and the data (D7–D0) to be programmed (See Table 10). Program-  
ming 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 pro-  
gramming 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 instruc-  
tion and will return to the standby state, when CS is brought high. A new CS falling edge  
is required to reinitiate the serial communication.
