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 4 and 16Kb densities and in standard 8-pin SOIC, TSSOP and PDIP packages. EERAM is available in 3.0 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.
Key features:
- I2C EERAM is a low-cost NVSRAM that requires no external battery to retain data
- Combines SRAM with EEPROM back-up on a single chip for lowest-cost NVSRAM solution
- Enables instant random writes to the array with no write-cycle delay
- Benefits applications which constantly or instantaneously record, update or monitor data
- Available in industrial and automotive temperature ranges
