*Note: Pins 3, 4 and 17, 18 are internally connected for 14-lead TSSOP socket compatibility.  
and 16-lead JEDEC SOIC (AT25128), 14-lead TSSOP (AT25128), 20-lead TSSOP (AT25128/256), 8-lead Leadless Array  
(AT25256), and 8-ball dBGA packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to  
5.5V) versions.  
The AT25128/256 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 sep-  
arate ERASE cycle is required before WRITE.  
BLOCK WRITE protection is enabled by programming the status register with top ¼, top ½ or entire array of write protec-  
tion. 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 that generates the serial clock.  
SLAVE: Because the Serial Clock pin (SCK) is always an input, the AT25128/256  
always operates as a slave.  
TRANSMITTER/RECEIVER: The AT25128/256 has seperate 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  
AT25128/256, 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 AT25128/256 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 AT25128/256.  
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 AT25128/256 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”.

SPI Serial Interface  
AT25128/256  
Functional  
Description  
The AT25128/256 is designed to interface directly with the synchronous serial periph-  
eral interface (SPI) of the 6800 type series of microcontrollers.  
The AT25128/256 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 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 instruc-  
tion  
.

Bit 0 = 0 (RDY) indicates the device is READY.  
Bit 0 = 1 indicates the write cycle is in progress.  
Bit 1 (WEN)  
Bit 1 = 0 indicates the device is not WRITE ENABLED. Bit 1 = 1 indicates  
the device is WRITE ENABLED.  
Bit 2 (BP0)  
Bit 3 (BP1)  
See Table 4.  
See Table 4.  
Bits 4 - 6 are 0s when device is not in an internal write cycle.  
Bit 7 (WPEN) See Table 5.  
Bits 0 - 7 are 1s during an internal write cycle.  
WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select  
one of four levels of protection. The AT25128/256 is divided into four array segments.  
Top quarter (1/4), top 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 pro-  
tection 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).

0872K–SEEPR–11/02  
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 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 AT25128/256 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  
(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 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 AT25128/256, 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 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 STA-  
TUS 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.

0872K–SEEPR–11/02  
AT25128/256  
The AT25128/256 is capable of a 64-byte PAGE WRITE operation. After each byte of  
data is received, the six low order address bits are internally incremented by one; the  
high order bits of the address will remain constant. If more than 64 bytes of data are  
transmitted, the address counter will roll over and the previously written data will be  
overwritten. The AT25128/256 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 fall-  
ing edge is required to re-initiate the serial communication.
