4.2.11 Memory

The memory of the Atmel^®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 simultaneously. The programming voltage is generated on-chip.

Block 0 contains the mode data, which are not normally transmitted (see Figure 4-5).

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 transmitted).
