DESCRIPTION
The M34C00 is a 384-bit serial EEPROM. The
bottom third of the memory area (from location 00h
to 0Fh) can be Write-protected using a specially
designed software Write-protection mechanism.
By sending the device a specific sequence, the
first 128 bits of the memory become permanently
Write-protected. Care must be taken when using
this sequence as its effect cannot be reversed.
The top third of the memory area (from location
20h to 2Fh) is already configured to give the
functional equivalence of a non-erasable memory.
That is, it is initialized to all 1s (FFh), and the user
is able to reset any number of those 1s to 0; but
there is no mechanism for the user to set a 0 back
to a 1.
The M34C00 is a 384-bit electrically erasable
programmable memory (EEPROM), organized as
48 x 8 bits.
