NVSRAM combines unlimited endurance with safe data storage at power loss
EERAM is a standalone SRAM with shadow EEPROM back-up on a single chip that helps to automatically retain the contents of the SRAM memory when system power is lost. The EERAM offers instant random writes to the array with no write-cycle delay. The I2C EERAM family is available in 4Kb and 16Kb densities and in standard 8-pin SOIC, TSSOP and PDIP packages. EERAM is available in 3.0V and 5.0V options and in industrial and automotive temperature ranges, of -40 to +85°C and -40 to +125°C respectively and is also available as an automotive-grade memory.
Comprised of two familiar and reliable memory technologies on a single chip, EEPROM and SRAM, EERAM offers a robust and dependable data solution that is also the lowest cost non-volatile SRAM solution. EERAM does not require an external battery to safely store data during a power-loss event. Instead, a small, external capacitor is used to provide the energy needed to store the contents of the SRAM on to the EEPROM when system power is lost.
The EERAM I2C PICtail Kit (AC500100) will be available in January 2017. The 47L04, 47C04, 47L16 and 47C16 are available in 8-pin SOIC, TSSOP and PDIP packages in volume production.
