Memory FRAM

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.

no wait time.
