October 20, 2016 —Microchip Technology. a provider of microcontroller, mixed-signal, analog and Flash-IP solutions, introduced the I2C EERAM memory. This is a non-volatile SRAM memory that is ideal for applications that need to constantly or instantaneously record, update or monitor data including metering, automotive and industrial applications.
EERAM is a standalone SRAM memory with shadow EEPROM back-up on a single chip that helps automatically retain 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 Kb and 16 Kb densities and comes 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 (-40°C to 85°C and -40°C to 125°C) and is available in automotive grade. Comprised of two familiar memory technologies on a single chip, EEPROM and SRAM, EERAM offers a data solution that is also a non-volatile SRAM solution. EERAM does not require an external battery to safely store data during a power loss event. Instead, an external capacitor is needed to provide the energy needed to store the contents of the SRAM on to the EEPROM when system power is lost.
