MB85RS16

FUJITSU SEMICONDUCTOR DATA SHEET Memory FRAM DS501-00014-6v0-E 16 K (2 K × 8) Bit SPI MB85RS16 ■ DESCRIPTION MB85RS16 is a 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. ■ FEATURES Bit configuration : 2,048 words × 8 bits Serial Peripheral Interface : SPI (Serial Peripheral Interface) Correspondent to SPI mode 0 (0, 0) and mode 3 (1, 1) Operating fre...
