Memory
The memory of the e5551 is a 264 bit EEPROM, which
is arranged in 8 blocks of 33 bits each. All 33 bits of a
block, including the lock bit, are programmed simulta-
neously. The programming voltage is generated on-chip.
Block 0 contains the mode data, which are not normally
transmitted (see figure 6).
Block 1 to 6 are freely programmable. Block 7 may be
used as a password. If password protection is not required,
it may be used for user data.
Bit 0 of every block is the lock bit for that block. Once
locked, the block (including the lockbit itself) cannot be
field-reprogrammed.
Data from the memory is transmitted serially, starting
with block 1, bit 1, up to block ‘MAXBLK’, bit 32.
‘MAXBLK’ is a mode parameter set by the user to a value
between 0 and 7 (if maxblk=0, only block 0 will be trans-
mitted).
