MB85RS2MT

FUJITSU SEMICONDUCTOR DATA SHEET Memory FRAM DS501-00023-0v01-E 2 M (256 K × 8) Bit SPI MB85RS2MT ■ DESCRIPTION MB85RS2MT is a FRAM (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. MB85RS2MT adopts the Serial Peripheral Interface (SPI). The MB85RS2MT is able to retain data without using a back-up battery, as is needed for SRAM. The memory cells used in the MB85RS2MT 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. MB85RS2MT does not take long time to write data like Flash memories or E2PROM, and MB85RS2MT takes no wait time. ■ FEATURES Bit configuration : 262,144 words × 8 bits Serial Peripheral Interface : SPI (Serial Peripheral Interface) Correspondent to SPI mode 0 (0, 0) and mode 3 (1, 1) ...
