www.DataSheet.co.kr Ordering number : ENA1473 LE25LA642CS Overview 64Kbit Serial SPI EEPROM (SPI Bus) The LE25LA642CS 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 LE25LA642CS has a 32 bytes page rewrite function that provides rapid data rewriting.
