Memory Overview Figure 1 Memory Overwiew SLE 4432 The SLE 4432 consists of 256 x 8 bit EEPROM main memory and a 32-bit protection memory with PROM functionality. The main memory is erased and written byte by byte. When ...
Page 11
SLE 4442 Additionally to the above functions the SLE 4442 provides a security code logic which controls the write/erase access to the memory. For this purpose the SLE 4442 contains a 4-byte security memory with an Error Counter EC (bit ...

Read Main Memory (SLE 4432 and SLE 4442) The command reads out the contents of the main memory (with LSB first) starting at the given byte address (N = 0…255 the end of the memory. After the ...
Page 17
Read Protection Memory (SLE 4432 and SLE 4442) The command transfers the protection bits under a continuous input of 32 clock pulses to the output. I/O is switched to high impedance additional pulse. The protection memory ...
Page 18
Update Main Memory (SLE 4432 and SLE 4442) The command programs the addressed EEPROM byte with the data byte transmitted. Depending on the old and new data, one of the following sequences will take place during the processing mode: ...
