Byte Write
Once the WEL bit is set, the user may execute a write
sequence, by sending a WRITE instruction, a 8-bit
address and data as shown in Figure 4. For the
CAT25040, bit 3 of the write instruction opcode
contains A8
address bit. Internal programming will
start after the low to high CS
transition. During an
internal write cycle, all commands, except for RDSR
(Read Status Register) will be ignored. The RDY
bit
will indicate if the internal write cycle is in progress
(RDY
high), or the the device is ready to accept
commands (RDY
low).
Page Write
After
sending
the
first
data
byte
to
the
CAT25010/20/40, the host may continue sending
data, up to a total of 16 bytes, according to timing
shown in Figure 5. After each data byte, the lower
order address bits are automatically incremented,
while the higher order address bits (page address)
remain unchanged. If during this process the end of
page is exceeded, then loading will “roll over” to the
first byte in the page, thus possibly overwriting
previoualy loaded data. Following completion of the
write cycle, the CAT25010/20/40 is automatically
returned to the write disable state.
