MB85RC128PNF-G-JNERE1

Memory IC Overview

The MB85RC128PNF-G-JNERE1 is a 128 Kbit (16 K × 8) ferroelectric random access memory (FRAM) manufactured by RAMXEED. It utilizes a two-wire I2C serial interface compliant with version 2.1, supporting standard and fast modes up to 400 kHz. The device operates within a supply voltage range of 2.7 V to 3.6 V and functions across an ambient temperature range of -40 °C to +85 °C. It features non-volatile data retention for at least 10 years at 75 °C and endurance exceeding 10^10 write cycles. The component is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

Non-volatile ferroelectric memory architecture eliminates the need for polling sequences after writing operations.
I2C bus interface allows connection of up to eight devices on the same bus using hardware address pins.
Hardware write protect pin enables complete memory array protection against overwriting.
High read/write endurance significantly outperforms traditional flash and EEPROM technologies.

Memory IC Applications

Data logging systems requiring frequent write cycles
Industrial control equipment operating in wide temperature ranges
Embedded systems needing battery-free data retention

Memory IC Procurement Notes

Verify the specific ordering suffix JNERE1 corresponds to the embossed carrier tape packaging format. Confirm that the manufacturer designation aligns with current RAMXEED product lines following corporate transitions. Ensure compatibility with existing I2C bus pull-up resistor configurations before finalizing procurement orders.

Memory IC Selection Notes

Select this component when high write endurance and low power consumption are critical requirements. The I2C interface simplifies PCB routing compared to parallel memories. Verify that the system voltage remains within the 2.7 V to 3.6 V operational window. Consider the 8-pin SOP footprint constraints during mechanical design integration.

Memory IC Part Context

This part belongs to the MB85RC series of I2C FRAM devices produced by RAMXEED. The series leverages ferroelectric process technology combined with silicon gate CMOS processes. These components are designed as standalone non-volatile memory solutions replacing traditional SRAM or EEPROM in applications demanding rapid write speeds and long-term data stability.
