LE25CB5122M
Serial SPI EEPROM
(SPI Bus)(512Kbit)
Overview
The LE25CB5122M is a 512Kbit 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 LE25CB5122M has a 128 bytes page rewrite function that provides rapid data
rewriting.
