DESCRIPTION

MB85RS256TY is a FeRAM (Ferroelectric Random Access Memory) chip in a configuration of 32,768

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.

MB85RS256TY adopts the Serial Peripheral Interface (SPI).

The MB85RS256TY is able to retain data without using a back-up battery, as is needed for SRAM.

The memory cells used in the MB85RS256TY 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 MB85RS256TY does not need any waiting time in writing process, the write cycle time of MB85RS256TY

is much shorter than that of Flash memories or E2PROM.
