MB85RS4MTPF-G-BCERE1

Memory IC Overview

The MB85RS4MTPF-G-BCERE1 is a 4 Mbit (512 K x 8 bit) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes Serial Peripheral Interface (SPI) communication and supports operating frequencies up to 40 MHz. The device operates within a supply voltage range of 1.8 V to 3.6 V and functions reliably across an ambient temperature range of -40 °C to +85 °C. It is housed in an 8-pin plastic SOP package with a 208 mil footprint.

Memory IC Feature Summary

• Nonvolatile memory architecture retaining data without backup power
• High endurance supporting 10^13 read/write operations per byte
• Supports SPI Mode 0 and Mode 3 for serial data transfer
• Includes sleep mode functionality for reduced power consumption

Memory IC Applications

• Data logging systems requiring frequent write cycles
• Industrial control applications with high reliability needs
• Embedded systems utilizing SPI microcontrollers
• Automotive electronics compliant with AEC-Q100 standards

Memory IC Procurement Notes

Verify the specific ordering suffix BCERE1 corresponds to the embossed carrier tape shipping form, as distinct from the tube variant. Confirm moisture sensitivity level requirements during storage and handling. Ensure the selected component matches the required 8-pin SOP package dimensions for PCB layout compatibility.

Memory IC Selection Notes

Select this component when high write endurance and fast non-volatile storage are required. It serves as a direct replacement for SRAM or Flash in applications needing rapid data retention without wait states. Verify that the system voltage falls within the 1.8 V to 3.6 V operational range and that the SPI interface timing aligns with the master controller specifications.

Memory IC Part Context

This part belongs to the MB85RS4MT series of FeRAM devices produced by RAMXEED Limited. The manufacturer continues to support existing product lines originally developed under Fujitsu Semiconductor Memory Solutions Limited, maintaining identical part numbering conventions while updating corporate branding.

Memory IC Replacement Considerations

MB85RS4MTPF-G-BCE1 is a confirmed substitute part number offering identical electrical characteristics but packaged in tubes instead of embossed carrier tape.
