Serial SPI EEPROM
(SPI Bus)(64Kbit)
LE25LB642CT
Overview
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.
