Fujitsu MB85RQ4ML
MB85RQ4ML is a FRAM (Ferroelectric Random Access Memory) chip in a configuration of 524,288 words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells. The MB85RQ4ML is able to retain data without using a back-up battery, as is needed for SRAM. The memory cells used in the MB85RQ4ML 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.| Part No. | MB85RQ4ML |

DESCRIPTION
MB85RQ4ML adopts the Quad Serial Peripheral Interface (QSPI) which can realize a high bandwidth such as Read and Write at 54 MB/s using four bi-directional pins (Quad I/O). MB85RQ4ML does not take long time to write data like Flash memories or E2PROM. MB85RQ4ML is able to write data at a high bandwidth without any waiting time and fits perfectly into Networking, Gaming, Industrial computing, Camera, RAID controllers, etc.●
