DESCRIPTION

MB85RS2MTY is a FeRAM (Ferroelectric Random Access Memory) chip in a configuration of 262,144

words  8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming

the nonvolatile memory cells. This product is specifically targeted for high-temperature environment such

as automotive applications.

MB85RS2MTY adopts the Serial Peripheral Interface (SPI).

The MB85RS2MTY is able to retain data without using a back-up battery, as is needed for SRAM.

The memory cells used in the MB85RS2MTY can be used for 1013 read/write operations, which is a significant

improvement over the number of read and write operations supported by Flash memory and E2PROM.

As MB85RS2MTY does not need any waiting time in writing process, the write cycle time of MB85RS2MTY

is much shorter than that of Flash memories or E2PROM.
