EEPROM 

4.8.1

 

Data EEPROM 24LC256T 

The EEPROM is empty on delivery. 
 

•

 

256 Kbit or not assembled 

•

 

3 decoded address lines 

•

 

Connected to I

2

C controller 1 of the CPU 

•

 

Device address is 

0x57 / 1010 111b

 

 
 
 

4.8.2

 

Configuration EEPROM SE97B 

The temperature sensor SE97BTP also contains a 2 Kbit (256 × 8 Bit) EEPROM. The EEPROM is divided into two parts. 
The lower 128 bytes (00h to 7Fh) can be set to Permanent Write Protected (PWP) mode or Reversible Write Protected (RWP) 

mode by software. The upper 128 bytes (80h to FFh) cannot be write-protected and can be used for general data storage.

Memory Map SE97BTP EEPROM 

 
 
The EEPROM can be accessed with the following two I

2

C addresses. 

•

 

EEPROM (Normal Mode): 

0x50 / 1010 000b

 

•

 

EEPROM (Protected Mode): 

0x30 / 0110 000b

 

 
The configuration EEPROM contains a standard reset configuration at delivery. The configuration EEPROM is only one of several 

options for storing the reset configuration. 
By means of the standard reset configuration in the EEPROM, a correctly configured system can always be achieved by simply 

changing the Reset Configuration Source. 
If the Reset Configuration Source is selected accordingly, 4 + 4 + 64 + 8 bytes = 80 bytes are required for the reset configuration. 

It can also be used for the Pre-Boot Loader PBL.
