MFR_EE_UNLOCK
Multiple writes to MFR_EE_UNLOCK with the appropriate unlock keys are used to enable MFR_EE_ERASE and MFR_
EE_DATA access and configure PEC.
Communication with the LTC3880 and programming of the NVM can be initiated when VDD33 is applied and VIN is
not. To enable the part in this state, use global address 5B command 0xBD data 0x2B followed by address 5B com-
mand 0xBD data 0xC4. When VIN is applied, a MFR_RESET must be issued to allow the PWM to be enabled and valid
ADCs to be read.
Writing 0x2B followed by 0xD4 clears PEC, resets the EEPROM address pointer and unlocks the part for EEPROM
erase and data command writes.
Writing 0x2B followed by 0xD5 sets the PEC, resets the EEPROM address pointer and unlocks the part for EEPROM
erase and data command writes.
Writing 0x2B followed by 0x91 and 0xE4 clears PEC, resets the EEPROM address pointer and unlocks the part for
EEPROM data reads of all locations.
Writing 0x2B followed by 0x91 and 0xE5 sets PEC, resets the EEPROM address pointer and unlocks the part for
EEPROM data reads of all locations.
MFR_EE_ERASE
A single write after the appropriate unlock key erases the EEPROM allowing subsequent data writes. This register may
be read to indicate if an EEPROM access is in progress.
A value of 0x2B will erase the EEPROM. If the part is busy writing or erasing the EEPROM a non-zero value will be
returned.
MFR_EE_DATA
Sequential writes or reads perform block loads or restores from the EEPROM. Successive MFR_EE_DATA word writes
will enter the EEPROM until it is full. Extra writes will lock the part. The first write is to the lowest address. The first
read returns the 16 bit EEPROM packing revision ID. The second read returns the number of 16 bit words available.
Subsequent reads return EEPROM data starting with the lowest address.
