EEPROM APPLICATION NOTES
This application note describes the programming procedures for the EEPROM modules and with details of various
techniques to preserve data protection.
Automatic Page Write
Page-mode write feature allows 1 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 30µs for the second byte. In the same manner each additional byte
of data can be loaded within 30µs. In case CE and WE are kept high for 100 µs after data input, EEPROM enters
erase and write mode automatically and only the input data are written into the EEPROM.
