Product Information

The Fujitsu MB85RS16 is a 16K Bit FRAM (Ferroelectric Random Access Memory) chip in a configuration of 2,048 words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells.

MB85RS16 adopts the Serial Peripheral Interface (SPI).

The MB85RS16 is able to retain data without using a back-up battery, as is needed for SRAM.

The memory cells used in the MB85RS16 can be used for 1012 read/write operations, which is a significant improvement over the number of read and write operations supported by Flash memory and E²PROM. MB85RS16 does not take long time to write data like Flash memories or E²PROM, and MB85RS16 takes no wait time.
