EEPROM APPLICATION NOTES  
This application note describes the programming procedures for the EEPROM modules and with details of various  
techniques to preserve data integrity.  
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. 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 of the preceding falling edge of either WE or CE. When CE and WE are kept high  
for 100µs after data input, the EEPROM enters the write mode automatically and the data input is written into the  
EEPROM.  
WE, CE Pin Operation  
During a write cycle, addresses are latched by the falling edge of WE or CE, and data is latched by the rising edge of  
WE or CE.  
All data sheets are subject to change without notice
