MB85RC04PNF-G-JNE1

Memory IC Overview

The MB85RC04PNF-G-JNE1 is a 4 Kbit (512 x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a two-wire I2C serial interface for communication, operating with a maximum clock frequency of 400 kHz. The device functions within an operating supply voltage range of 2.7 V to 3.6 V and supports an ambient temperature range from -40°C to +85°C. It is housed in an 8-pin plastic SOP package with a lead pitch of 1.27 mm.

Memory IC Feature Summary

• Nonvolatile memory architecture retains data without requiring a backup battery or polling sequences after write operations.
• High endurance capability with read/write cycles reaching at least 10^12 per byte.
• Hardware-based write protection via the WP pin allows disabling write operations while maintaining read access.
• Supports multiple slave devices on a single bus through configurable hardware address pins.

Memory IC Applications

• Data logging systems requiring high endurance and fast write speeds
• Industrial control equipment operating in wide temperature environments
• Smart metering applications needing reliable nonvolatile storage

Memory IC Procurement Notes

Verify the specific suffix JNE1 corresponds to tube packaging when sourcing this component. Confirm that the 2.7 V to 3.6 V supply voltage requirement aligns with the target system design, as it differs from 5V variants. Ensure compatibility with standard I2C pull-up resistor configurations for the SDA and SCL lines.

Memory IC Selection Notes

Select this part for designs prioritizing high write endurance over flash or EEPROM technologies. It is suitable for applications where frequent data updates are necessary without degradation. Consider the 8-pin SOP footprint for PCB layout constraints. Verify that the master controller supports the required I2C timing parameters for fast mode operation.

Memory IC Part Context

This component belongs to the MB85RC04 series of FeRAM devices produced by RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited. The series offers nonvolatile memory solutions using ferroelectric process technology. The MB85RC04 variant specifically provides 4 Kbit capacity with I2C connectivity, distinguishing it from SPI-based or higher-capacity models in the lineup.
