MB85RC64VPNF-G-AMERE2

Memory IC Overview

The MB85RC64VPNF-G-AMERE2 is a 64 Kbit (8 K × 8 bit) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes an I2C two-wire serial interface for communication, supporting standard mode up to 100 kHz, fast mode up to 400 kHz, and fast mode plus up to 1 MHz. The device operates within a supply voltage range of 3.0 V to 5.5 V and functions across an ambient temperature range of -40°C to +85°C. It features high write endurance of at least 10^12 cycles per byte and data retention exceeding 200 years at +35°C. The component is housed in an 8-pin plastic SOP package with a 150mil footprint.

Memory IC Feature Summary

• Nonvolatile memory architecture utilizing ferroelectric process technology that retains data without backup batteries.
• I2C bus interface allowing connection of up to eight devices on the same bus using hardware address pins.
• High-speed write operations that eliminate the need for acknowledge polling sequences typically required by Flash or EEPROM.
• Hardware write protection capability via the WP pin to secure the entire memory array against unintended overwriting.

Memory IC Applications

• Data logging systems requiring frequent updates with high endurance.
• Industrial control units needing reliable nonvolatile storage in varying temperatures.
• Smart metering applications for storing consumption data securely.
• Embedded systems utilizing I2C buses for configuration parameter storage.

Memory IC Procurement Notes

Verify the specific ordering suffix AMERE2 corresponds to the embossed carrier tape packaging format when sourcing components. Confirm that the supplier provides documentation verifying RoHS compliance and REACH status as specified in the manufacturer datasheet. Ensure moisture sensitivity level 3 handling procedures are followed during assembly to prevent damage during reflow soldering processes.

Memory IC Selection Notes

Select this component when an I2C interface is preferred over SPI for system integration. Choose this FeRAM variant for applications demanding significantly higher write endurance compared to traditional EEPROM technologies. Consider the 3.0 V to 5.5 V operating voltage range for compatibility with various logic levels. Evaluate the 8-pin SOP package constraints against available PCB real estate requirements.

Memory IC Part Context

This part belongs to the MB85RC64V family of 64 Kbit FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited. The series maintains original part numbering conventions while transitioning manufacturing support. The MB85RC64V line specifically targets applications requiring robust nonvolatile memory with fast write speeds and low power consumption in a compact surface-mount package.

Memory IC Replacement Considerations

Direct substitutes include MB85RC64TAPNF-G-BDE1. Other compatible variants within the same family include MB85RC64PNF-G-JNE1 and MB85RC64VPNF-G-JNERE1, which share identical electrical specifications but differ in shipping form factors such as tubes versus tape and reel configurations.
