MB85RQ8MLXPF-G-BCE1

Memory IC Overview

The MB85RQ8MLX is an 8 Mbit Ferroelectric Random Access Memory (FeRAM) organized as 1,048,576 words by 8 bits. It utilizes a Quad Serial Peripheral Interface (QSPI) with four bidirectional pins to achieve 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 clock frequencies up to 108 MHz for most commands. It features high endurance of 10^13 read/write operations per byte and retains data without backup batteries.

Memory IC Feature Summary

• Supports SPI, Dual SPI, and Quad SPI modes with XIP capability
• High endurance of 10^13 read/write cycles per byte
• Nonvolatile memory retention exceeding 200 years at +35°C
• Configurable latency control for optimized read throughput

Memory IC Applications

• Networking equipment
• Industrial computing systems
• RAID controllers
• Camera modules

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package and temperature grade. Confirm that the 1.7 V to 1.95 V supply range aligns with the system design. Ensure compatibility with QSPI controller interfaces supporting the necessary command set. Check for moisture sensitivity handling requirements during assembly.

Memory IC Selection Notes

Select this component when high-speed serial access and extreme write endurance are required. It serves as a drop-in replacement for SRAM in battery-backed applications due to its nonvolatile nature. Consider the 16-pin SOP package constraints and the specific low-voltage operating range when designing the power delivery network.

Memory IC Part Context

This part belongs to the MB85RQ8ML series of FeRAM devices manufactured by RAMXEED. It represents a continuation of Fujitsu Semiconductor's ferroelectric memory technology. The device is designed to replace volatile SRAM or slow Flash memory in applications demanding fast random access and high durability.

Memory IC Replacement Considerations

Direct pin-compatible substitutes within the same family include the MB85RQ4MLX (4 Mbit). Verify interface compatibility when substituting lower density parts.
