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 30µ s for the second byte. In the same manner each additional byte

of data can be loaded within 30µ s of the preceding falling edge of either WE or CE. When CE and WE are kept high

for 100µ s 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.
