Automatic standby
If CMOS levels (V
more the memory enters automatic standby where the internal supply current is reduced to
the standby supply current, I
operation is in progress.
Special bus operations
Additional bus operations can be performed to read the electronic signature and also to
apply and remove block protection. These bus operations are intended for use by
programming equipment and are not usually used in applications. They require V
applied to some pins.
Electronic signature
The memory has two codes, the manufacturer code and the device code, that can be read
to identify the memory. These codes can be read by applying the signals listed in
