The MB85RC512LY is a non-volatile memory with 512Kbit memory density and operates at a low power supply voltage from 1.7V to 1.95V. It features extremely low operating current such as a maximum of 0.4mA at 3.4MHz operation.
This product guarantees 10 trillion read/write cycle times in the high temperature at 125 degrees C. The FeRAM product is optimal for industrial robots and automotive applications such as Advanced Driver-Assistance Systems (ADAS).

Since the new FeRAM has an I2C interface, customers using an I2C interface for their platform do not need major design modifications in developing an end-product by using the memory parts.
Using the above features, the new FeRAM product can solve the following issues arising from the use of memory products.

The automotive-grade FeRAM family has variations of 3.3V and 1.8V operation for both I2C- and SPI-interface products. With the launch of MB85RC512LY, the AEC-Q100 compliant FeRAM family has added 7 new products since the last year. In addition, 4 new types of 1Mbit products are currently under development.
