Fujitsu FRAM Nonvolatile MB85RS256BPNF-G-JNERE1 256K SPI Integrated Storage Memory IC Chip for Automotive

الوصف

â–  DESCRIPTION

MB*5RS**6B is a FRAM (Ferroelectric Random Access Memory) chip in a configuration of *2,**8

words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the

nonvolatile memory cells.

MB*5RS**6B adopts the Serial Peripheral Interface (SPI).

The MB*5RS**6B is able to retain data without using a back-up battery, as is needed for SRAM.

The memory cells used in the MB*5RS**6B can be used for ***2 read/write operations, which is a significant

improvement over the number of read and write operations supported by Flash memory and E2PROM.

MB*5RS**6B does not take long time to write data like Flash memories or E2PROM, and MB*5RS**6B

takes no wait time.
