Write to Memory Array (WRITE)
As shown in
Figure 12.
, to send this instruction to
the device, Chip Select (S) is first driven Low. The
bits of the instruction byte, address byte, and at
least one data byte are then shifted in, on Serial
Data Input (D).
The instruction is terminated by driving Chip Se-
lect (S) High at a byte boundary of the input data.
In the case of
Figure 12.
, this occurs after the
eighth bit of the data byte has been latched in, in-
dicating that the instruction is being used to write
a single byte. The self-timed Write cycle starts,
and continues for a period t
WC
(as specified in
Ta-
ble 19.
to
Table 23.
), at the end of which the Write
in Progress (WIP) bit is reset to 0.
If, though, Chip Select (S) continues to be driven
Low, as shown in
Figure 13.
, the next byte of input
data is shifted in, so that more than a single byte,
starting from the given address towards the end of
the same page, can be written in a single internal
Write cycle.
Each time a new data byte is shifted in, the least
significant bits of the internal address counter are
incremented. If the number of data bytes sent to
the device exceeds the page boundary, the inter-
nal address counter rolls over to the beginning of
the page, and the previous data there are overwrit-
ten with the incoming data. (The page size of
these devices is 32 bytes).
The instruction is not accepted, and is not execut-
ed, under the following conditions:
–
if the Write Enable Latch (WEL) bit has not
been set to 1 (by executing a Write Enable
instruction just before)
–
if a Write cycle is already in progress
–
if the device has not been deselected, by Chip
Select (S) being driven High, at a byte
boundary (after the eighth bit, b0, of the last
data byte that has been latched in)
–
if the addressed page is in the region
protected by the Block Protect (BP1 and BP0)
bits.

Note: Depending on the memory size, as shown in
Table 7.
, the most significant address bits are Don’t Care.
