Automatic Standby
If CMOS levels (V
more the memory enters Automatic Standby where the internal Supply Current is reduced to
the CMOS Standby Supply Current, I
Bus Read 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
and
Block Protection and Blocks Unprotection
Each block can be separately protected against accidental Program or Erase. Protected
blocks can be unprotected to allow data to be changed.
There are two methods available for protecting and unprotecting the blocks, one for use on
programming equipment and the other for in-system use. For further information refer to
Application Note AN1122, Applying Protection and Unprotection to M29 Series Flash.
