EEPROM
EEPROM I2C / SPI Memory
Extremely Low Power. Extremely Fast.
Offering fast access and extremely low power, our EEPROMs outperform competitive devices. With no pre-erase cycle required, the write cycle time is up to 100x faster and consumes up to 100x less power. This makes them perfect for battery operated and energy harvesting applications such as camera modules, medical devices, small wearables, and smart tags.
Ultra-low Power
Fast Read / Write
Sterilization Tolerant
Magnetic Field Tolerant
UV Tolerant
CBRAM Technology
CBRAM is a resistive RAM technology that provides power, speed, and cost benefits over other non-volatile memory technologies. Our EEPROM devices take advantage of CBRAM technology to deliver extremely low power and faster performance than competitive devices.
