MB85RC04PNF-G-AME2

Memory IC Overview

The MB85RC04PNF-G-AME2 is a 4 Kbit (512 words x 8 bits) ferroelectric random access memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes an I2C two-wire serial interface for communication, operating at a maximum frequency of 400 kHz. The device functions within a supply voltage range of 2.7 V to 3.6 V and supports an ambient operating temperature from -40°C to +85°C. It is housed in an 8-pin plastic SOP package with a 150mil width.

Memory IC Feature Summary

• Nonvolatile data retention without requiring a backup battery
• High write endurance exceeding 10^12 cycles per byte
• Elimination of polling sequences required after write operations
• Hardware-based write protection via dedicated pin

Memory IC Applications

• Data logging systems requiring frequent updates
• Industrial control devices needing reliable nonvolatile storage
• Smart metering applications with low standby current requirements
• Embedded systems utilizing I2C bus architecture

Memory IC Procurement Notes

Verify the specific ordering suffix AME2 corresponds to the tray packaging format when sourcing this component. Confirm that the procurement channel provides valid RoHS compliance documentation. Ensure the supplier source matches the manufacturer's authorized distribution network to guarantee product authenticity and traceability.

Memory IC Selection Notes

Select this component for designs requiring high-speed writes without programming wait times. It is suitable for applications where battery-backed SRAM is undesirable due to size or maintenance constraints. Verify that the system power supply remains strictly within the 2.7 V to 3.6 V range to ensure proper operation and data integrity.

Memory IC Part Context

This part belongs to the MB85RC04 series of FeRAM devices produced by RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited. The series maintains original part numbering conventions while transitioning manufacturing support. The technology replaces traditional EEPROMs and Flash memories in applications demanding superior endurance and faster write speeds.

Memory IC Replacement Considerations

Direct substitutes include MB85RC04PNF-G-JNE1 and MB85RC04PNF-G-AMERE2. These alternatives share identical electrical specifications and pinouts but differ in shipping formats such as tubes or embossed carrier tape.
