A low-cost, low-risk memory solution has been announced by Microchip, it offers unlimited endurance and safe data storage at power loss. This I2C EERAM memory is an easy to implement, Non-Volatile SRAM (NVSRAM) that can be used by applications that need to constantly or instantaneously record, update or monitor data in sectors which include metering, automotive and industrial.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 dataCombines SRAM with EEPROM back-up on a single chip for lowest-cost NVSRAM solutionEnables instant random writes to the array with no write-cycle delayBenefits applications which constantly or instantaneously record, update or monitor dataAvailable in industrial and automotive temperature rangesReference:KY32-BQ2201SN-NKY32-DP8421AV-20KY32-DS1321KY32-MXD1210CSA+
