LE25CB643TT-BH: 64 kb SPI CMOS Serial EEPROM

The LE25CB643TT-BH is serial peripheral interface EEPROM (Electrically Erasable and Programmable ROM). This device realizes high speed and a high level reliability by incorporating high performance CMOS EEPROM technology. This device is compatible with SPI memory protocol, therefore it is best suited for application that requires re-writable nonvolatile parameter memory. And this device has 32bytes page write function for high speed data re-write.

Features
  • Capacity : 64k bits (8k × 8 bits)
  • Single supply voltage : 2.7V to 5.5V
  • Operating temperature : -40ºC to +85ºC
  • Interface : SPI Mode0 and Mode3 correspondence
  • Operating clock frequency : 5MHz
  • Low Power consumption: Standby : 3μA (max.): Read : 1mA (max.): Write : 3mA (max.)
  • Automatic page write mode : 32 Bytes
  • Write cycle time : 5ms
  • Erase/Write cycles : 106 cycles
  • Data Retention : 20 years
  • High reliability : Adopts proprietary symmetric memory array configuration (USP6947325)Incorporates a feature to prohibit write operations under low voltage conditions.
Benefits
