CAT25C128/256
Document No. 1018, Rev. I
The WPEN (Write Protect Enable) is an enable bit for the
WP pin. The WP pin and WPEN bit in the status register
control the programmable hardware write protect fea-
ture. Hardware write protection is enabled when
WP is
low and WPEN bit is set to high. The user cannot write
to the status register (including the block protect bits and
the WPEN bit) and the block protected sections in the
memory array when the chip is hardware write pro-
tected. Only the sections of the memory array that are
not block protected can be written. Hardware write
protection is disabled when either WP pin is high or the
WPEN bit is zero.
DEVICE OPERATION
Write Enable and Disable
The CAT25C128/256 contains a write enable latch. This
latch must be set before any write operation. The device
powers up in a write disable state when Vcc is applied.
WREN instruction will enable writes (set the latch) to the
device. WRDI instruction will disable writes (reset the
latch) to the device. Disabling writes will protect the
device against inadvertent writes.
READ Sequence
The part is selected by pulling
CS low. The 8-bit read
instruction is transmitted to the CAT25C128/256, followed
by the 16-bit address(the three Most Significant Bit is
don’t care for 25C256 and four most significant bits are
don't care for 25C128).
After the correct read instruction and address are sent,
the data stored in the memory at the selected address is
shifted out on the SO pin. The data stored in the memory
at the next address can be read sequentially by continuing
to provide clock pulses. The internal address pointer is
automatically incremented to the next higher address
after each byte of data is shifted out. When the highest
address (7FFFh for 25C256 and 3FFFh for 25C128) is
reached, the address counter rolls over to 0000h allowing
the read cycle to be continued indefinitely. The
readoperation is terminated by pulling the
CS high.
