MB85RS1MTPNF-G-JNERE1

Memory IC Overview

The MB85RS1MTPNF-G-JNERE1 is a 1 Mbit (128 K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a Serial Peripheral Interface (SPI) for communication and operates within a supply voltage range of 1.8 V to 3.6 V. The device supports clock frequencies up to 25 MHz at lower voltages, 30 MHz at higher voltages, and up to 40 MHz when using the Fast Read command. It features high endurance of 10^13 read/write operations per byte and data retention exceeding 10 years at +85°C. The component is housed in an 8-pin plastic SOP package with a lead pitch of 1.27 mm.

Memory IC Feature Summary

• Non-volatile memory architecture utilizing ferroelectric process technology that retains data without backup power.
• High write endurance capability supporting 10^13 read/write cycles per byte, significantly exceeding Flash and EEPROM limits.
• Integrated SPI interface compatible with Mode 0 and Mode 3, allowing connection to multiple devices via microcontrollers.
• Low power consumption profile featuring standby current of 120 µA maximum and sleep mode functionality.

Memory IC Applications

• Data logging systems requiring frequent write cycles and long-term data retention.
• Industrial control applications operating within wide temperature ranges.
• Embedded systems needing battery-free volatile-like memory performance.
• Smart metering and utility infrastructure monitoring equipment.

Memory IC Procurement Notes

Verify the specific ordering suffix JNERE1 corresponds to the embossed carrier tape shipping form with a minimum quantity of 1500 units. Confirm compatibility with standard SOP-8 footprint dimensions during PCB layout. Ensure design accounts for Moisture Sensitivity Level 3 requirements regarding floor life and reflow soldering profiles. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Memory IC Selection Notes

Select this component when high endurance and fast write speeds are critical compared to traditional Flash memory. Choose the SOP-8 package variant if surface mount assembly is required over through-hole options. Consider the 1.8 V to 3.6 V operating range for low-power embedded designs. Evaluate the need for block protection features provided by the status register for security-sensitive applications.
