AT25HP256(1)
AT25HP512
The AT25HP256/512 provides 262,144/524,288 bits of serial electrically erasable pro-
grammable read only memory (EEPROM) organized as 32,768/65,536 words of 8-bits
each. The device is optimized for use in many industrial and commercial applications
where high-speed, low-power, and low-voltage operation are essential. The
AT25HP256/512 is available in a space saving 8-lead PDIP (AT25HP256/512), 8-lead
EIAJ SOIC (AT25HP256), 16-lead JEDEC SOIC (AT25HP512), 8-lead Leadless Array

The AT25HP256/512 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 top ¼, top ½
or entire array of write protection. Separate Program Enable and Program Disable
instructions are provided for additional data protection. Hardware data protection is pro-
vided 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 AT25HP256/512
always operates as a slave.
TRANSMITTER/RECEIVER: The AT25HP256/512 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
AT25HP256/512, 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 AT25HP256/512 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 SO will remain in
a high impedance state.
HOLD: The HOLD pin is used in conjunction with the CS pin to select the
AT25HP256/512. 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 AT25HP256/512 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”.

1113L–SEEPR–3/06
The AT25HP256/512 is designed to interface directly with the synchronous serial
peripheral interface (SPI) of the 6800 type series of microcontrollers.
The AT25HP256/512 utilizes an 8-bit instruction register. The list of instructions 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.

See Table 8.
Bits 4-6 are “0”s when device is not in an internal write cycle.
Bit 7 (WPEN) See Table 9.
Bits 0-7 are “1”s during an internal write cycle.
WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select
one of four levels of protection. The AT25HP256/512 is divided into four array seg-
ments. 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 protection levels and corresponding status register control bits are shown in Table
8.
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).

0000 - 7FFF/0000 - FFFF
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 AT25HP256/512 via the 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 (see Table 10).
Upon completion, any data on the SI line will be ignored. The data (D7–D0) at the spec-
ified 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 AT25HP256/512, 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 op-code is transmitted via the SI line followed by the byte
address and the data (D7–D0) to be programmed (see Table 10). 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 pro-
gramming cycle.
The AT25HP256/512 is capable of a 128-byte page write operation. After each byte of
data is received, the seven low-order address bits are internally incremented by one; the
high-order bits of the address will remain constant. If more than 128 bytes of data are
transmitted, the address counter will roll over and the previously written data will be
overwritten. The AT25HP256/512 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 reinitiate the serial communication.

guaranteed if less than 128 bytes of data is received (byte write is not supported).
