LE25LB642CT

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. Features Capacity Single supply voltage Serial interface Operating clock frequency Low current dissipation Page write function Rewrite time Number of rewrite times Data retention period High reliability : 64Kbits (8K×8bits) : 1.8V to 3.6V : SPI Mode0, Mode3 supported : 5MHz (2.5V to 3.6V), 3MHz (1.8V to 3.6V) : Standby : 3μA (max.) : Active (Read) : 1mA (max.) : Active (Rewrite) : 3mA (max.) : 32bytes : 10ms : 105 times/Page(Page=32Byte) : 20years : Adopts SANYO’s proprietary symmetric memory array configuration (USP6947325) Incorporates a feature to prohibit write operations under low voltage conditions. * This product is licensed from Silicon Storage Technology, Inc.
