www.DataSheet.co.kr Ordering number : ENA1342A LE25LB643 Overview Serial SPI EEPROM (SPI Bus) (64Kbit) The LE25LB643 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 LE25LB64
