www.DataSheet.co.kr Ordering number : ENA1471 LE25LB642CT Overview Serial SPI EEPROM (SPI Bus)(64Kbit) The LE25LB642CT is a 64Kbit EEPROM that supports serial peripheral interface (SPI). It realizes high speed operation and high level reliability by incorporating SANYO’s high performance CMOS EEPROM technology. The interface is compatible with SPI bus protocol, therefore, it is best suited for applications that require small-scale rewritable nonvolatile parameter memory. Moreover, the LE25LB642CT has a 32 bytes page rewrite function that provides rapid data rewriting.
