MB85RQ4MLPF-G-BCE1

Memory IC Overview

The MB85RQ4MLPF-G-BCE1 is a 4 Mbit Ferroelectric Random Access Memory (FeRAM) IC manufactured by RAMXEED. It features a Quad Serial Peripheral Interface (Quad SPI) with four bidirectional I/O pins, enabling high bandwidth data transfer rates up to 54 MB/s. The device operates on a single power supply voltage ranging from 1.7 V to 1.95 V and supports an operating frequency of up to 108 MHz for most commands. It is housed in a 16-pin plastic Small Outline Package (SOP).

Memory IC Feature Summary

• Utilizes ferroelectric process technology for nonvolatile memory storage without requiring backup batteries.
• Supports Quad SPI interface with multiple modes including QPI and XIP for enhanced throughput.
• Offers high endurance with 10^13 read/write operations per byte.
• Provides long data retention capabilities exceeding 200 years at +35°C.

Memory IC Applications

• Networking equipment
• Gaming systems
• Industrial computing
• Camera devices
• RAID controllers

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package and tape/reel configuration. Confirm the voltage range aligns with system requirements as this part uses a single low-voltage supply. Check datasheet revisions for any pinout or command set updates before finalizing integration.

Memory IC Selection Notes

Select this component when high-speed serial access and extreme write endurance are critical. The Quad SPI interface reduces pin count compared to parallel memories while maintaining high data rates. Ensure the system voltage regulator can maintain stability within the 1.7 V to 1.95 V operating window.

Memory IC Part Context

This part belongs to the MB85RQ4ML series of FeRAM devices. RAMXEED continues to support existing products under the original Fujitsu Semiconductor naming conventions. The series is designed to replace SRAM, Flash, and EEPROM in applications demanding fast write speeds and high reliability.

Memory IC Replacement Considerations

Direct substitutes include other parts within the MB85RQ4ML family with compatible interfaces and voltages. Verify pin compatibility and command set adherence when considering alternative vendors' FeRAM solutions.
