MB85RS128BPNF-G-JNE1

Memory IC Overview

The MB85RS128BPNF-G-JNE1 is a 128Kbit (16 K x 8) ferroelectric random access memory (FeRAM) utilizing SPI interface technology. It operates within a voltage range of 2.7 V to 3.6 V and supports clock frequencies up to 33 MHz for most commands, with READ operations limited to 25 MHz. The device features high endurance of 10^12 read/write cycles per byte and data retention exceeding 10 years at +85°C. It is housed in an 8-pin plastic SOP package and functions as an SPI slave.

Memory IC Feature Summary

Non-volatile storage capability without requiring backup batteries
High write endurance significantly surpassing Flash and EEPROM technologies
Supports standard SPI modes 0 and 3 for serial communication
Includes hardware block protection and write protect mechanisms

Memory IC Applications

Data logging systems requiring frequent write cycles
Industrial control applications needing reliable non-volatile storage
Embedded systems integrating with microcontrollers via SPI
Metering devices tracking cumulative usage data

Memory IC Procurement Notes

Verify the specific suffix JNE1 corresponds to the tube packaging format required for your assembly process. Confirm that the operating environment stays within the specified -40°C to +85°C temperature range to ensure data retention guarantees are met. Check for moisture sensitivity level 3 handling requirements during storage and reflow soldering procedures.

Memory IC Selection Notes

Select this component when high cycle endurance is critical compared to flash-based alternatives. Ensure the host controller supports SPI mode 0 or 3 and can operate within the 2.7V to 3.6V supply voltage window. Consider the 8-pin SOP footprint constraints and verify that the 128Kbit capacity aligns with system memory requirements.

Memory IC Part Context

This part belongs to the MB85RS128B family of FeRAM chips manufactured by RAMXEED. It replaces legacy Fujitsu semiconductor memory solutions while maintaining identical part numbering. The technology leverages ferroelectric processes to provide fast, low-power, and durable non-volatile memory storage for embedded applications.
