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 pro-
tection. Separate program enable and program disable
instructions are provided for additional data protection.
Hardware data protection is provided via the WP pin to pro-
tect against inadvertent write attempts to the status regis-
ter. The HOLD pin may be used to suspend any serial
communication without resetting the serial sequence.
*NOTICE:
Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions beyond those indicated in the operational sec-
tions of this specification is not implied. Exposure to
absolute maximum rating conditions for extended
periods may affect device reliability.

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 reg-
ister. All WP pin functions are enabled when the WPEN bit
is set to “1”.
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).
SPI Serial Interface
MSB: The Most Significant Bit (MSB) is the first bit
transmitted and received.
AT25HP256/512
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 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 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 regis-
ter. If the internal write cycle has already been initiated, WP
going low will have no effect on any write operation to the
AT25HP256/512

AT25HP256/512
Functional Description
The AT25HP256/512 is designed to interface directly with
the synchronous serial peripheral interface (SPI) of the
6800 type series of microcontrollers.
Table 3. Read Status Register Bit Definition
Bit
Definition
Bit 0 (RDY)
Bit 0 = 0 (RDY) indicates the device is
READY. Bit 0 = 1 indicates the write cycle is in
progress.
The AT25HP256/512 utilizes an 8-bit instruction register.
The list of instructions and their operation codes are con-
tained in Table 1. All instructions, addresses, and data are
transferred with the MSB first and start with a high-to-low
CS transition.
Bit 1 (WEN)
Bit 1= 0 indicates the device is not WRITE
ENABLED. Bit 1 = 1 indicates the device is
WRITE ENABLED.

Bits 0-7 are 1s during an internal write cycle.
WRITE STATUS REGISTER (WRSR): The WRSR instruc-
tion allows the user to select one of four levels of protec-
tion. The AT25HP256/512 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 protection levels and corresponding status reg-
ister control bits are shown in Table 4.
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.
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).
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.
Table 4. Block Write Protect Bits
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.

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 protec-
tion 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.

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.
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 STATUS REGISTER (RDSR) Instruc-
tion. 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 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.
READ
SEQUENCE
(READ): Reading
the
AT25HP256/512 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.
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.

WRITE SEQUENCE (WRITE): In order to program the
AT25HP256/512, two separate instructions must be exe-
cuted. 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
Don’t Care Bits
NOTE: 128-byte PAGE WRITE operation only. Content of
the page in the array will not be guaranteed if less than 128
bytes of data is received (byte write is not supported).
