MB85RS256APNF-G-JNE1

Memory IC Overview

The MB85RS256APNF-G-JNE1 is a 256 Kbit (32K x 8) Ferroelectric Random Access Memory (FRAM) integrated circuit manufactured by RAMXEED. It utilizes the Serial Peripheral Interface (SPI) for communication and operates within a supply voltage range of 3.0 V to 3.6 V. The device supports a maximum clock frequency of 25 MHz and functions reliably across an operating temperature range of -40°C to +85°C. It is housed in an 8-pin plastic Small Outline Package (SOP).

Memory IC Feature Summary

Non-volatile memory architecture utilizing ferroelectric process technology.
High endurance capability supporting up to 10 billion read/write operations.
Supports SPI Mode 0 and Mode 3 with dedicated hold and write protect pins.

Memory IC Applications

Data logging systems requiring frequent write cycles.
Industrial control applications needing reliable non-volatile storage.
Embedded systems utilizing microcontrollers equipped with SPI ports.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and check for Product Change Notices (PCN) regarding package or resin modifications. Ensure the specific ordering suffix matches the required tube packaging configuration for your assembly line.

Memory IC Selection Notes

Select this component when high write endurance and fast access times are critical compared to Flash or EEPROM alternatives. Verify that the system power supply strictly adheres to the 3.0 V to 3.6 V operating range. Ensure the PCB layout accommodates the 8-pin SOP footprint and provides adequate thermal management for the specified temperature range.

Memory IC Part Context

This part belongs to the MB85RS256A FRAM family, originally developed by Fujitsu Semiconductor and now produced by RAMXEED. It serves as a drop-in replacement for legacy SRAM designs where data retention without backup batteries is required. The device integrates a status register for block protection and write enable latching.
