VALUE
DESCRIPTION
This command copies the shadow RAM to the target EEPROM block.
Copy Data
0
1
42h
44h
Copy Data commands that target locked blocks are ignored. While the
Copy Data command is executing, the EEC bit in the EEPROM register is
set to 1, and Write Data commands with MAddr set to any address within
the target block are ignored. Read Data and Write Data commands with
MAddr set outside the target block are processed while the copy is in
progress. The Copy Data command execution time, t EEC , is 2ms typical
and starts after the FCMD byte is acknowledged. Subsequent Copy or
Lock commands must be delayed until the EEPROM programming cycle
completes.
Recall Data
0
1
B2h
B4h
This command recalls the contents of the targeted EEPROM block to its
shadow RAM.
This command locks (write-protects) the targeted EEPROM block. The
0
63h
LOCK bit in the EEPROM register must be set to 1 before the lock
command is executed. If the LOCK bit is 0, the lock command has no
Lock

66h
effect. The lock command is permanent; a locked block can never be
written again. The Lock command execution time, t EEC , is 2ms typical and
starts after the FCMD byte is acknowledged. Subsequent Copy or Lock
commands must be delayed until the EEPROM programming cycle
completes.
64-BIT UNIQUE ID
The DS2782 can be special ordered with a unique, factory-programmed ID that is 64 bits in length. The first eight
bits are the product family code (B2h for DS2782). The next 48 bits are a unique 40-bit serial number followed by
0x82h. The last eight bits are a cyclic redundancy check (CRC) of the first 56 bits (see Figure 24). The 64-bit ID
can be read as 8 bytes starting at memory address F0h. The 64-bit ID is read only.
