MB85RQ8MXPF-G-BCERE1

Memory IC Overview

The MB85RQ8MX is an 8 Mbit (1,048,576 words × 8 bits) Ferroelectric Random Access Memory (FeRAM) featuring a Quad Serial Peripheral Interface (QSPI). It supports operating frequencies up to 108 MHz and operates on a single power supply ranging from 2.7 V to 3.6 V. The device provides high endurance of 10^13 read/write operations per byte and data retention exceeding 200 years at +35°C. It is housed in a 16-pin plastic SOP package.

Memory IC Feature Summary

• Supports SPI, Dual SPI, and Quad SPI interfaces with bidirectional I/O pins for high bandwidth data transfer.
• Features non-volatile memory cells offering 10^13 read/write endurance without requiring backup batteries.
• Includes XIP mode capability allowing direct code execution from the memory array.
• Configurable latency control bits allow optimization of dummy cycles for various read command speeds.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix BCERE1 against official documentation to confirm tape and reel packaging specifications. Ensure compatibility with the required voltage range and temperature ratings for the target application environment before finalizing procurement decisions.

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 non-volatility. Consider the 16-pin SOP package constraints and 108 MHz interface speed requirements during system design.

Memory IC Part Context

This part belongs to the MB85RQ8MX family of FeRAM devices manufactured by RAMXEED Limited. The manufacturer continues to support existing products while maintaining original Fujitsu part numbering conventions. The technology leverages ferroelectric materials to provide fast, durable, and non-volatile storage solutions.

Memory IC Replacement Considerations

Direct substitutes within the same family include parts with different capacities or interface modes, such as the MB85RQ4M series. Verify pinout compatibility and voltage levels when cross-referencing with other FeRAM models.
