MB85RQ8MXPF-G-BCE1

Memory IC Overview

The MB85RQ8MX is an 8 Mbit Ferroelectric Random Access Memory (FeRAM) organized as 1,048,576 words by 8 bits. It features a Quad Serial Peripheral Interface (QSPI) supporting SPI, Dual SPI, and Quad SPI modes with operation frequencies up to 108 MHz. The device operates on a single power supply ranging from 2.7 V to 3.6 V and supports read/write endurance of 10^13 cycles per byte. Data retention exceeds 200 years at +35°C. It is housed in a 16-pin plastic SOP package.

Memory IC Feature Summary

• Supports high-bandwidth data transfer via Quad I/O pins enabling read and write speeds up to 54 MB/s.
• Provides non-volatile memory storage without requiring backup batteries, unlike SRAM.
• Offers significantly higher endurance compared to Flash memory and E2PROM technologies.
• Enables immediate data writing without the waiting times associated with Flash or E2PROM.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix codes against the manufacturer's official documentation to ensure correct interface and voltage specifications. Confirm that the 16-pin SOP package aligns with your PCB footprint requirements. Check for any recent Product Change Notifications (PCN) regarding manufacturing updates or material changes before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when high-speed serial communication and extreme write endurance are required. It is suitable for applications needing fast random access without the latency of flash programming. Ensure the system voltage falls within the 2.7 V to 3.6 V range. Consider the 108 MHz clock capability for bandwidth-intensive tasks.
