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).
