This application note describes the programmng procedures for each EEPROMmodule (four in each MCM) and
details of various techniques to preserve data protection.
Automatic Page Write
Page-mode write feature allows from1 to 128 bytes of data to be written into the EEPROM in a single write cycle, and
allows the undefined data within 128 bytes to be written corresponding to the undefined address (A0 to A6). Loading
the first byte of data, the data load window opens 30 μs for the second byte. In the same manner each additional byte
of data can be loaded within 30 μs. In case CE and WE are kept high for 100 μs after data input, the EEPROMenters
erase and write mode automatically and only the input data are written into the EEPROM.
